Find Your Delaware Rebates
Seven bodies run the Delaware programmes we track: the state’s own DNREC Division of
Climate, Coastal and Energy; Energize Delaware, which is the Delaware Sustainable Energy
Utility; Delmarva Power; Chesapeake Utilities on the gas side; Delaware Electric Cooperative
for its members; Efficiency Smart, which delivers energy-efficiency programmes for the nine
municipal electric utilities in the DEMEC consortium; and the City of Newark Electric
Department, through DEMEC.
What follows from that is easy to get wrong, in both directions. Thirty-four of the
sixty-nine programmes are administered at state level by DNREC or Energize Delaware; the other
thirty-five are run by, or on behalf of, the utility or co-operative that serves the address. So
a large part of this list does not turn on who sends your bill — but state-level administration
does not by itself mean a programme is open to every Delaware customer. Nine of those
thirty-four are DNREC Green Energy Program and Solar + Storage Pilot grants, and every one of
the nine is published for Delmarva Power customers only, so a municipal or co-operative
household cannot use that route. On the commercial side the dividing line is different again.
DNREC publishes the Energy Efficiency Investment Fund as open to non-residential, commercial,
industrial, local government, governmental and non-profit entities in Delaware that pay the
Public Utility Tax, and states that it verifies payment from the utility bills filed with the
application; Energize Delaware publishes its parallel Fund for Non-Profits as open to Delaware
schools, local governments and non-profits that do not pay that tax. The charge is not always
labelled “Public Utility Tax” on a bill — DNREC notes that some municipal electric companies
code it differently — and DNREC asks applicants who are unsure to contact its programme team
before applying. Ask the administrator which half applies to you before you commission work.
If a municipal electric utility serves your address — there are nine of them — you reach
those rebates through DEMEC and Efficiency Smart. A Delaware Electric Cooperative member has a
different set again, and a Delmarva Power customer a third. The boundaries do not follow
mailing addresses: for much of Delaware more than one utility serves the same ZIP code, and a
Dover or Milford postal address can be municipal, co-operative or Delmarva, while a Newark one
can be either the city’s own electric department or Delmarva. Your bill names which.
The list below is every Delaware programme we hold — 69 of them. Twenty-seven are for
households, 29 are for businesses and other non-residential customers, and 13 are open to
both, so most of the list is not a household programme; the group headings say which is which.
Each card carries the benefit as the administrator publishes it, the timing as published, a
link to the official programme page, and the date we last checked it. Confirm current amounts
and eligibility with the administrator before you spend money or sign anything: the figures
move, and the administrator’s own page is the only current record. We are a publisher, not an
administrator — we do not decide eligibility, process applications or pay rebates, and listing
a programme here is not a recommendation of it.
Frequently Asked Questions
Which Delaware utility serves my address?
Delaware’s territory is split between Delmarva Power, Delaware Electric Cooperative, and
nine municipal electric utilities — Clayton, Dover, Lewes, Middletown, Milford, New Castle,
Newark, Seaford and Smyrna. On the gas side, the programmes we track run through Chesapeake Utilities and Delmarva. More
than one utility serves the same ZIP code across much of the state, so a postal address does
not settle it. Your bill names the utility. Once you know it, the administrator named on each
card below tells you whose programme it is.
What is Efficiency Smart, and why does it appear on so many cards?
Efficiency Smart is a programme administrator rather than a utility. It delivers
energy-efficiency programmes for the nine municipal electric utilities that make up the
Delaware Municipal Electric Corporation, so if one of those nine bills you, your rebate is
generally administered by Efficiency Smart even though your bill comes from the town. Dover
was the last to join, in July 2025. Check with your town’s electric department, or with
Efficiency Smart, before you buy equipment.
Is Energize Delaware the same as DNREC?
No. Energize Delaware is the Delaware Sustainable Energy Utility, a separate non-profit body
from the state’s DNREC Division of Climate, Coastal and Energy, and the two run different
programmes. Both appear in the list below, named on each card, so you can see which one to
contact.
Do these programmes have deadlines?
Each card states the timing as the administrator publishes it. Many Delaware programmes
are limited by funding as well as, or instead of, by a date, which means they can close when
the money is committed regardless of what the calendar says. Where that is what the
administrator states, the card says so. Because that can change without notice, confirm the
programme is still open and still funded with the administrator before you order equipment or
sign a contract.
Are commercial and non-residential programmes included?
Yes — most of the list is. Of the 69 programmes, 29 are for businesses and other
non-residential customers and a further 13 are open to both households and businesses. They
are listed in their own groups below, under “Programs for businesses” and “Programs for homes
& businesses”.
How current is this?
Every card shows the date we last checked that programme against its administrator’s own
page, and links to that page. Treat what you read here as a starting point and confirm it with
whoever runs the programme. Some programmes also interact with federal or state tax
provisions; we do not give tax advice, and you should speak to a qualified tax professional
about your own situation.

Programs for homes
Efficiency Smart, for DEMEC member municipal electric utilities 13 programs
Heat Pump Water Heater Rebate
Estimated benefit: $300. $300 on an ENERGY STAR certified heat pump water heater. Limit one rebate per year. Rebates are available to individual homeowners and renters only; developers and landlords must apply through Large Business Solutions. Offers are valid while funds are available and may change without prior notice.
Timing: No general closing date; rebates are good while funds are available and may change without notice. The window air conditioner uplift ends 30 September 2026.
“"Heat Pump Water Heater Rebate — $300 … Limit one heat pump water heater rebate per year." — Efficiency Smart, Home Energy Rebates (Newark, Delaware and Milford, Delaware), retrieved 2026-09-24.”
Our energy expert: Three hundred dollars back on an ENERGY STAR heat pump water heater, one a year. This is the largest single-appliance rebate on the municipal schedule and the one with the best arithmetic behind it — a heat pump water heater costs about half as much to run as a conventional electric tank, so the rebate is a discount on a change that keeps paying.
Cold Climate Air Source Heat Pump Rebate
Estimated benefit: $350 (under two tons) or $750 (two tons or more). $350 for a system under two tons, $750 for two tons or more. Cold climate air source heat pumps are designed for cooler climates and extract heat from air well below 0°F. Limit two rebates per year. Rebates are available to individual homeowners and renters only; developers and landlords must apply through Large Business Solutions. Offers are valid while funds are available and may change without prior notice.
Timing: No general closing date; rebates are good while funds are available and may change without notice. The window air conditioner uplift ends 30 September 2026.
“"Cold Climate Air Source Heat Pump Rebate — $350 (less than two tons) or $750 (two or more tons) … Limit two cold climate air source heat pump rebates per year." — Efficiency Smart, Home Energy Rebates (Newark, Delaware and Milford, Delaware), retrieved 2026-09-24.”
Our energy expert: Note the gap between this and the ordinary heat pump rebate — $750 against $100 for a system of two tons or more. A cold climate unit is specified to keep producing heat well below freezing rather than falling back on resistance strips, which is exactly what decides whether a heat pump actually saves money through a Delaware January. The rebate is structured to push you toward the right equipment; take the hint.
Smart Thermostat Rebate
Estimated benefit: $100. $100 on an ENERGY STAR certified smart thermostat. Limit two rebates per year. Rebates are available to individual homeowners and renters only; developers and landlords must apply through Large Business Solutions. Offers are valid while funds are available and may change without prior notice.
Timing: No general closing date; rebates are good while funds are available and may change without notice. The window air conditioner uplift ends 30 September 2026.
“"Smart Thermostat Rebate — $100 … Limit two smart thermostat rebates per year." — Efficiency Smart, Home Energy Rebates (Newark, Delaware and Milford, Delaware), retrieved 2026-09-24.”
Our energy expert: A hundred dollars covers most of the cost of an ENERGY STAR smart thermostat, and you can claim two in a year — which matters in a house with two zones. The saving comes from the schedule and the remote control, not the brand.
Central Air Conditioner Rebate
Estimated benefit: $100. $100 on a qualifying central air conditioner. Split systems must meet SEER2 of 15.2 or better and EER2 of 12.0 or better; single-package systems SEER2 15.2 and EER2 11.5. Limit two rebates per year. Rebates are available to individual homeowners and renters only; developers and landlords must apply through Large Business Solutions. Offers are valid while funds are available and may change without prior notice.
Timing: No general closing date; rebates are good while funds are available and may change without notice. The window air conditioner uplift ends 30 September 2026.
“"Central Air Conditioner Rebate — $100 … To qualify, models must meet the following requirements: Split system: SEER2 >= 15.2, EER2 >=12.0; Single package: SEER2>= 15.2, EER2 >=11.5." — Efficiency Smart, Home Energy Rebates (Newark, Delaware and Milford, Delaware), retrieved 2026-09-24.”
Our energy expert: A hundred dollars on a qualifying central air conditioner, with a real efficiency floor attached: SEER2 of at least 15.2 and EER2 of at least 12.0 on a split system. Check the EER2 as well as the SEER2 — EER2 is the hot-day number, and a unit can clear the SEER2 bar and miss the other.
Air Source Heat Pump Rebate
Estimated benefit: $100. $100 on an ENERGY STAR certified air source heat pump. Limit two rebates per year. Rebates are available to individual homeowners and renters only; developers and landlords must apply through Large Business Solutions. Offers are valid while funds are available and may change without prior notice.
Timing: No general closing date; rebates are good while funds are available and may change without notice. The window air conditioner uplift ends 30 September 2026.
“"Air Source Heat Pump Rebate — $100 … Limit two air source heat pump rebates per year." — Efficiency Smart, Home Energy Rebates (Newark, Delaware and Milford, Delaware), retrieved 2026-09-24.”
Our energy expert: A hundred dollars on a standard ENERGY STAR air source heat pump. Before you take it, price the cold climate version — the rebate on that is $750 for two tons or more, and the difference in equipment cost is often smaller than the difference in rebate.
Pool Pump Rebate
Estimated benefit: $250 (above ground) or $500 (in-ground). $250 for an above-ground pool pump, $500 for an in-ground pool pump. Rebates are available to individual homeowners and renters only; developers and landlords must apply through Large Business Solutions. Offers are valid while funds are available and may change without prior notice.
Timing: No general closing date; rebates are good while funds are available and may change without notice. The window air conditioner uplift ends 30 September 2026.
“"Pool Pump Rebate — $250 (above ground) or $500 (in-ground)" — Efficiency Smart, Home Energy Rebates (Newark, Delaware and Milford, Delaware), retrieved 2026-09-24.”
Our energy expert: Five hundred dollars on an in-ground pool pump, $250 above ground. Pool pumps are one of the largest single loads in a house that has one — often more than the fridge and the water heater together — so a variable-speed replacement is unusually good value even before the rebate.
Window Air Conditioner Rebate
Estimated benefit: $50 standard. Currently $150 per unit, up to four per year, through 31 October 2026.
Timing: No general closing date; rebates are good while funds are available and may change without notice. The $150 window air conditioner uplift runs through 31 October 2026.
“"Window Air Conditioner Rebate — $50 Now $150 Through September 30! … Limit four window air conditioner rebates per year." — Efficiency Smart, Home Energy Rebates (Newark, Delaware and Milford, Delaware), retrieved 2026-09-24.”
Our energy expert: Fifty dollars normally, and currently $150 per unit through 31 October 2026, up to four units a year. The uplift applies at all nine DEMEC municipal utilities. Confirm the current amount with Efficiency Smart before buying.
Refrigerator Rebate
Estimated benefit: $50. $50 on an ENERGY STAR certified refrigerator. Qualifying models must be 10 to 30 cubic feet. Limit two rebates per year. Rebates are available to individual homeowners and renters only; developers and landlords must apply through Large Business Solutions. Offers are valid while funds are available and may change without prior notice.
Timing: No general closing date; rebates are good while funds are available and may change without notice. The window air conditioner uplift ends 30 September 2026.
“"Refrigerator Rebate — $50 … Qualifying models must be 10 to 30 cubic feet. Limit two refrigerator rebates per year." — Efficiency Smart, Home Energy Rebates (Newark, Delaware and Milford, Delaware), retrieved 2026-09-24.”
Our energy expert: Fifty dollars on an ENERGY STAR refrigerator between 10 and 30 cubic feet. Worth pairing with the appliance recycling reward if the old one is going to end up running in the garage — a second fridge from the 1990s will cost you more each year than this rebate is worth.
Clothes Washer Rebate
Estimated benefit: $50. $50 on an ENERGY STAR certified clothes washer. Limit one rebate per year. Can be combined with the $50 electric clothes dryer rebate for $100 off an ENERGY STAR certified all-in-one washer/dryer combination unit. Rebates are available to individual homeowners and renters only; developers and landlords must apply through Large Business Solutions. Offers are valid while funds are available and may change without prior notice.
Timing: No general closing date; rebates are good while funds are available and may change without notice. The window air conditioner uplift ends 30 September 2026.
“"Clothes Washer Rebate — $50 … You can combine our $50 clothes washer rebate and our $50 electric clothes dryer rebate for $100 off an ENERGY STAR-certified combination all-in-one washer/dryer." — Efficiency Smart, Home Energy Rebates (Newark, Delaware and Milford, Delaware), retrieved 2026-09-24.”
Our energy expert: Fifty dollars on an ENERGY STAR washer. If you are looking at an all-in-one washer/dryer combination, the washer and dryer rebates stack to $100 on the single machine — complete either the washer or the dryer fields on the form, not both.
Electric Clothes Dryer Rebate
Estimated benefit: $50. $50 on an ENERGY STAR certified electric clothes dryer. Limit one rebate per year. Combines with the clothes washer rebate for $100 on an all-in-one combination unit. Rebates are available to individual homeowners and renters only; developers and landlords must apply through Large Business Solutions. Offers are valid while funds are available and may change without prior notice.
Timing: No general closing date; rebates are good while funds are available and may change without notice. The window air conditioner uplift ends 30 September 2026.
“"Electric Clothes Dryer Rebate — $50 … Featuring sensor drying technology, they automatically turn off when clothes are dry." — Efficiency Smart, Home Energy Rebates (Newark, Delaware and Milford, Delaware), retrieved 2026-09-24.”
Our energy expert: Fifty dollars on an ENERGY STAR electric dryer. The saving is in the sensor: it stops when the clothes are dry instead of running out a timer, which is where most of the wasted energy in a dryer goes.
Dehumidifier Rebate
Estimated benefit: $30. $30 on an ENERGY STAR certified dehumidifier. Limit five rebates per year. Rebates are available to individual homeowners and renters only; developers and landlords must apply through Large Business Solutions. Offers are valid while funds are available and may change without prior notice.
Timing: No general closing date; rebates are good while funds are available and may change without notice. The window air conditioner uplift ends 30 September 2026.
“"Dehumidifier Rebate — $30 … Limit five dehumidifier rebates per year." — Efficiency Smart, Home Energy Rebates (Newark, Delaware and Milford, Delaware), retrieved 2026-09-24.”
Our energy expert: Thirty dollars, and you can claim five in a year — which is aimed at whole-house and crawlspace situations rather than a single bedroom. A dehumidifier runs for months at a time in a Delaware summer, so the efficiency difference is real.
Air Purifier Rebate
Estimated benefit: $20. $20 on an ENERGY STAR certified air purifier. Models must have a PM2.5 CADR rating of 30 or higher. Limit five rebates per year. Rebates are available to individual homeowners and renters only; developers and landlords must apply through Large Business Solutions. Offers are valid while funds are available and may change without prior notice.
Timing: No general closing date; rebates are good while funds are available and may change without notice. The window air conditioner uplift ends 30 September 2026.
“"Air Purifier Rebate — $20 … To qualify, models must have a PM2.5 CADR rating of 30 or higher. Limit five air purifier rebates per year." — Efficiency Smart, Home Energy Rebates (Newark, Delaware and Milford, Delaware), retrieved 2026-09-24.”
Our energy expert: Twenty dollars, up to five a year, on an ENERGY STAR air purifier rated PM2.5 CADR 30 or higher. Small money, but air purifiers run continuously, so the efficient ones are worth finding.
Appliance Recycling Rewards
Estimated benefit: Free pickup and a $75 reward for responsibly recycling an eligible refrigerator, freezer, window air conditioner or dehumidifier. This promotion ran through 30 September 2026 and has concluded.
Timing: The $75 promotion ran through 30 September 2026 and has concluded.
“"Get $75 For Recycling An Eligible Appliance Through September 30 — For a limited time, Efficiency Smart is offering a free pickup and a $75 reward for responsibly recycling an eligible refrigerator, freezer, window air conditioner, or dehumidifier." — Efficiency Smart, Newark, DE and Milford, DE community offers, retrieved 2026-09-24.”
Our energy expert: Seventy-five dollars and a free collection for an old fridge, freezer, window air conditioner or dehumidifier. That promotion ran through 30 September 2026 and has concluded; Efficiency Smart says to check back in 2027. The second fridge in the garage is the classic case, so it is worth asking what the program offers when it returns.
DNREC Division of Climate, Coastal and Energy 8 programs
Green Energy Program — Photovoltaic Grant (residential)
Estimated benefit: $0.80 per watt up to 50,000 watts, to a maximum grant of $10,000. A residential system under a power purchase agreement or lease receives NO incentive. Notes printed on the same sheet: incentives apply to Delmarva Power and Light customers only; applications submitted more than 12 months after installation completion are ineligible; no grant may exceed 50% of total project cost; total project cost must be $6.00 per watt or less; a Solar Shade Analysis showing a Total Solar Resource Fraction of 70% or greater is required. Applicants must sign their Solar Renewable Energy Credits over to the Delaware Sustainable Energy Utility and register as an eSupplier with Delaware's Division of Accounting before payment.
Timing: No closing date. Applications submitted more than 12 months after installation completion are ineligible. Rates effective 1 July 2026; checked 2026-09-24.
“"Photovoltaic grants ($/Watt) — Residential: Up To 50,000 Watts $0.80, Maximum Grant $10,000. Residential PPA/Lease: No Incentive." — Green Energy Program Incentives, DNREC, effective July 1, 2026, p. 1.”
Our energy expert: DNREC's Green Energy Program publishes a residential solar rate of $0.80 per watt, up to 50,000 watts, to a maximum grant of $10,000. Two conditions decide whether you receive anything: the program covers Delmarva Power and Light customers only, and a leased system or a power purchase agreement receives no incentive — the grant is for systems you own. No grant may exceed 50% of total project cost, the installed price must be $6.00 per watt or less, and a Solar Shade Analysis showing a Total Solar Resource Fraction of 70% or greater is required. Apply within 12 months of installation completion; you also sign your Solar Renewable Energy Credits over to the Delaware Sustainable Energy Utility. Confirm the current schedule with DNREC before contracting.
Green Energy Program — Geothermal Heat Pump Grant (residential)
Estimated benefit: $900 per ton, to a maximum grant of $10,000. Geothermal systems must meet a minimum EER rating above 18 and a COP above 3.6 at partial load. Notes printed on the same sheet: incentives apply to Delmarva Power and Light customers only; applications submitted more than 12 months after installation completion are ineligible; no grant may exceed 50% of total project cost; total project cost must be $6.00 per watt or less; a Solar Shade Analysis showing a Total Solar Resource Fraction of 70% or greater is required. Applicants must sign their Solar Renewable Energy Credits over to the Delaware Sustainable Energy Utility and register as an eSupplier with Delaware's Division of Accounting before payment.
Timing: No closing date. Applications more than 12 months after installation completion are ineligible.
“"Geothermal Heat Pump Grants ($/Ton) — Residential: Per Ton $900, Maximum Grant $10,000." and "Geothermal systems must meet minimum EER rating of >18 and COP >3.6 at partial load." — Green Energy Program Incentives, DNREC, effective July 1, 2026, p. 1.”
Our energy expert: Nine hundred dollars a ton toward a home geothermal system, up to $10,000 — which covers a system of about eleven tons, so in practice the cap will not bind on a house. The efficiency floor is what to watch: EER above 18 and COP above 3.6 at partial load, and 'at partial load' is the phrase that catches people, because it is not the headline rating on the datasheet. The grant is for Delmarva Power customers, and no grant can exceed half the total project cost.
Green Energy Program — Solar Water Heating Grant (residential)
Estimated benefit: $1.00 per kWh saved, for a water-heater-only system or one with integrated heating, to a maximum grant of $5,000. Grants are calculated on the $/kWh saved OG-300 rating issued by the Solar Rating Certification Corporation; a system with an SRCC OG-300 certification must have the energy savings calculation completed and stamped by a Delaware licensed professional engineer. Notes printed on the same sheet: incentives apply to Delmarva Power and Light customers only; applications submitted more than 12 months after installation completion are ineligible; no grant may exceed 50% of total project cost; total project cost must be $6.00 per watt or less; a Solar Shade Analysis showing a Total Solar Resource Fraction of 70% or greater is required. Applicants must sign their Solar Renewable Energy Credits over to the Delaware Sustainable Energy Utility and register as an eSupplier with Delaware's Division of Accounting before payment.
Timing: No closing date. Applications more than 12 months after installation completion are ineligible.
“"Solar Water heating Grants ($/kWh Saved) — Residential: SWH Water Heater Only $1.00, SWH With Integrated Heating $1.00, Maximum Grant $5,000." — Green Energy Program Incentives, DNREC, effective July 1, 2026, p. 1.”
Our energy expert: A dollar for every kilowatt-hour a year the system is certified to save, up to $5,000. Because the grant is paid on the SRCC OG-300 rating rather than on what you spend, the certification number is the figure that decides your cheque — get it from the installer before you sign anything. Note the extra step Delaware adds: the savings calculation has to be completed and stamped by a Delaware licensed professional engineer, which is a cost and a lead time to budget for.
Green Energy Program — Wind Turbine Grant (residential)
Estimated benefit: $0.85 per watt for the first 5,000 watts and $0.25 per watt from 5,001 to 50,000 watts, to a maximum grant of $15,000. Photovoltaic and wind turbine grants are no longer limited to systems of 500 kW and under, and applications are evaluated by site address rather than by electric meter. Notes printed on the same sheet: incentives apply to Delmarva Power and Light customers only; applications submitted more than 12 months after installation completion are ineligible; no grant may exceed 50% of total project cost; total project cost must be $6.00 per watt or less; a Solar Shade Analysis showing a Total Solar Resource Fraction of 70% or greater is required. Applicants must sign their Solar Renewable Energy Credits over to the Delaware Sustainable Energy Utility and register as an eSupplier with Delaware's Division of Accounting before payment.
Timing: No closing date. Applications more than 12 months after installation completion are ineligible.
“"Wind Turbine Grants ($/Watt) — Residential: 0 - 5,000 Watts $0.85, 5,001 - 50,000 Watts $0.25, Maximum Grant $15,000." — Green Energy Program Incentives, DNREC, effective July 1, 2026, p. 1.”
Our energy expert: Eighty-five cents a watt on the first five kilowatts, then twenty-five cents a watt up to fifty kilowatts, capped at $15,000. The step down at 5 kW is steep — a ten-kilowatt turbine earns $4,250 for the first half and $1,250 for the second — so the economics favor a modest machine well sited over a large one. Delmarva Power customers only, and no grant exceeds half the project cost.
Solar + Storage Pilot Program — residential battery grant
Estimated benefit: $250 per kWh of battery storage, to a maximum grant of $6,000, with no hardware size cap. No grant may exceed 50% of the total eligible storage cost. The applicant must be a Delmarva Power electric customer; the battery must be permanently installed behind the meter at the installation address, purchased and owned by the applicant, and must have received final interconnection approval from Delmarva Power no more than one year before the application. The battery must carry at least a 10-year manufacturer warranty, must be capable of islanding from the grid during outages, and once available must be enrolled with Delmarva Power in an active dispatch program for 10 years. Households that already have solar may add a battery and still receive the grant if the solar received interconnection approval within the last 12 months and was approved for the Green Energy Program's solar rebate.
Timing: Effective 11 August 2026. A pilot, so treat the closing date as unpublished rather than open-ended. Interconnection approval must be no more than one year old at application.
“"Battery Storage Grants ($/kWh) — Residential: Incentive Rates $250 per kWh, Maximum Grant $6,000, Hardware Size Cap None. Note: No grant may exceed 50% of the total eligible storage cost." — Solar + Storage Pilot Program Guidelines and Incentives, DNREC, effective August 11, 2026, p. 1.”
Our energy expert: Effective 11 August 2026, DNREC's Solar + Storage pilot publishes a residential rate of $250 per kWh of battery storage, to a maximum grant of $6,000 and never more than 50% of eligible storage cost. Three conditions matter more than the rate. The battery must be purchased and owned by you and installed behind the meter at the installation address — not a unit a solar company owns on your roof. Final Delmarva Power interconnection approval must be less than twelve months old when you apply, so a battery added to a three-year-old array does not qualify. And the battery is committed to Delmarva's dispatch program for ten years once that program exists, on a unit carrying at least a 10-year manufacturer warranty and able to island during outages. It is a pilot, so confirm with DNREC that applications are still open before you contract.
Low- to Moderate-Income Solar Pilot Program — low-income pathway
Estimated benefit: A cost-free solar installation of up to 4.0 kW. Applicants must meet the Weatherization Assistance Program income eligibility guidelines — see the Income Limits tab. Total income is verified through a tax return, and each adult household member (census definition of household) completes a form 4506-C. Applications and approvals are obtained through the Weatherization Assistance Program by calling the Energy Coordinating Agency on 302-504-6111.
Timing: Access is through the Weatherization Assistance Program, which operates a waiting list.
“"Low-income qualified homes will receive a cost-free solar installation of up to 4.0 kW." and "The LMI program will be used to develop a statewide solar program that will provide services for low- to moderate-income homes regardless of their electric utility service territory." — DNREC, Low- to Moderate-Income Solar Pilot Program, retrieved 2026-09-24.”
Our energy expert: This is the one Delaware solar program that does not care who your electric utility is. DNREC publishes a cost-free solar installation of up to four kilowatts for households within the Weatherization Assistance Program income limits — $66,000 for a family of four. You apply through Weatherization, not through the solar program: ring the Energy Coordinating Agency on 302-504-6111. Expect a waiting list, expect to produce tax returns for every adult in the house, and apply again each year if you are not served within twelve months.
Low- to Moderate-Income Solar Pilot Program — moderate-income pathway
Estimated benefit: A solar installation with 70% of the cost paid by the LMI Solar Program and 30% by the homeowner, for a system size up to 6.0 kW. Moderate income is defined by the state area median income and verified through a tax return, with each adult household member completing a form 4506-C. Applications are submitted through a contractor the household selects from DNREC's approved list: CMI Solar & Electric or KW Solar Solutions in New Castle and Kent counties, Clean Energy USA in Sussex County.
Timing: Checked 2026-09-24.
“"Qualified moderate-income households will receive a solar installation that has 70% paid for by the LMI Solar Program and 30% by the homeowner for a system size up to 6.0 kW." — DNREC, Low- to Moderate-Income Solar Pilot Program, retrieved 2026-09-24.”
Our energy expert: If your income is above the limit for the low-income pathway but moderate against Delaware's area median, this is the route. The published split is 70% of the cost paid by the LMI Solar Program and 30% by the homeowner, on a system up to 6.0 kW, where the program's conditions are met. Income is verified from a tax return, with each adult household member completing a form 4506-C. You apply through a contractor you select from DNREC's approved list — CMI Solar & Electric or KW Solar Solutions in New Castle and Kent counties, Clean Energy USA in Sussex. Get estimates from each one available to you, because the quote is the variable, not the published split.
Weatherization Assistance Program
Estimated benefit: A free home energy audit followed by weatherization measures installed at no charge: air sealing, caulking, glazing, weather-stripping and crack patching; replacement of broken glass; attic, wall and floor insulation and ventilation; sealing of heating and cooling ducts; insulation for water heaters and hot and cold water pipes; and other items the auditor recommends. DNREC states that many households have cut their energy bill by 30 to 50 percent. Eligibility is by household size and income — see the Income Limits tab. Once eligible, applicants join a waiting list prioritized by need, the age and special needs of residents, and annual funding. Not all applicants are served in a program year; those not served within 12 months must reapply annually to verify income eligibility.
Timing: Operates year-round with no application window, but runs a waiting list. Applicants not served within 12 months must reapply every year.
“"Professionals from the Weatherization Assistance Program can help low-income households fix these problems by assessing the home and providing weatherstripping, insulation, energy efficient light bulbs and other energy-saving measures – all free of charge. Thousands of Delawareans have benefited from this program; many have cut their energy bill by 30 to 50 percent." — DNREC, Weatherization Assistance Program, retrieved 2026-09-24.”
Our energy expert: Free, not subsidised. If your household is within the income limits, a trained auditor goes through the house and a contractor installs whatever the audit calls for — insulation, air sealing, duct sealing, pipe and water-heater insulation — at no cost to you. DNREC says many households cut their bills by 30 to 50 percent. Ring the Energy Coordinating Agency on 302-504-6111. Two practical points: there is a waiting list prioritized by need and by the age and health of the people in the house, and if you are not served within twelve months you must reapply to re-verify your income. DNREC publishes its LMI Solar Pilot as being applied for through this program; that pilot sets its own income verification and its own limits, and is listed separately here. Ask the Energy Coordinating Agency which programs an application covers before relying on either.
Energize Delaware (Delaware Sustainable Energy Utility) 4 programs
Home Performance with ENERGY STAR®
Estimated benefit: Rebates per measure, e.g. air sealing $900 (20%) / $1,300 (30%) / $1,800 (40%); attic insulation $900 (R-19) or $1,100 (R-30); wall insulation $1,800; crawlspace encapsulation $1,000; heat pump $800 (Tier 1) or $1,600 (Tier 2); heat pump water heater $1,100; ENERGY STAR smart thermostat $150; hybrid heat pump + furnace $1,450 (Tier 1) or $2,250 (Tier 2). Customer pays $50 for the assessment. Weatherization/HVAC/water-heating rebates are capped at the stated amount or 50% of installed cost, whichever is lower; air sealing and duct sealing at 75% of installed cost. Assessment incentive capped at $400. Mini-split rebates capped at $4,000 per customer.
Timing: Sheet carries 'Effective Date: 11/01/2024'; checked 2026-09-24.
“"Air Sealing 20% Improvement $900 … Heat Pumps Tier 1 (≥ 16 SEER2 and ≥ 11.5 EER2 and ≥ 7.8 HSPF2, Multi-stage Capacity) $800 … Heat Pump Water Heater $1,100 … Customer Cost for Assessment $50" — Home Performance with ENERGY STAR, Energy Checkups and Funding, doc 048-1167-10-072025, effective 11/01/2024, p. 1.”
Our energy expert: If you own a home in Delaware, the Home Performance with ENERGY STAR assessment is the gate to the rest of the schedule, and you pay $50 for it. Once a program contractor has been through the house, Energize Delaware's published schedule sets amounts per measure: $900 at 20%, $1,300 at 30% and $1,800 at 40% improvement, $900 at R-19 or $1,100 at R-30 for attic insulation, $1,800 for wall insulation, $800 or $1,600 for a heat pump by tier, and $1,100 for a heat pump water heater. Each is capped at the stated amount or 50% of installed cost, whichever is lower — 75% of installed cost for air and duct sealing — so the published figure is a ceiling, not a cheque. Mini-splits cap at $4,000 per customer. Bundle air sealing with a heat pump within three months and there is another $300.
Assisted Home Performance with ENERGY STAR®
Estimated benefit: Higher rebates for the same measures, e.g. air sealing $1,100 / $1,500 / $2,000; attic insulation $1,100 (R-19) or $1,400 (R-30); wall insulation $2,400; heat pump $1,200 (Tier 1) or $2,200 (Tier 2); heat pump water heater $1,350; smart thermostat $200; hybrid heat pump + furnace $2,300 or $3,300. Customer pays $25 for the assessment. Weatherization, HVAC and water-heating rebates capped at 75% of installed cost. Assessment incentive capped at $425. Mini-split rebates capped at $5,500 per customer.
Timing: Checked 2026-09-24.
“"Assisted Home Performance with ENERGY STAR … Customer Cost for Assessment $25 … Air Sealing 40% Improvement $2,000 … Wall Insulation (min 50% of walls) $2,400 … Heat Pump Water Heater $1,350" — Home Performance with ENERGY STAR, doc 048-1167-10-072025, effective 11/01/2024, p. 1.”
Our energy expert: If your household income is at or below the Energize Delaware limits, the same program pays more and asks less. The assessment costs $25 instead of $50, and every rebate steps up — $2,000 for the deepest air sealing tier against $1,800, $2,400 for wall insulation against $1,800, $1,350 for a heat pump water heater against $1,100. The cost cap is also gentler: 75% of installed cost across the board rather than 50%. The income table is on the Income Limits tab of this workbook; it is the same table the EV charger rebate uses.
Home Energy Check-Up and Counseling (HEC2)
Estimated benefit: Free in-home energy check-up with energy counselling and direct-install measures. Value of the installed package not yet confirmed from an Energize Delaware document — see Internal note on the QA tab.
Timing: Checked 2026-09-24.
“"The HEC2 Program is designed to empower Delaware residents by providing access to high-quality energy-efficiency education, products and services." — Delmarva Power, Ways to Save → For Your Home → Delaware, retrieved 2026-09-24. Corroborating figure from a different administrator: "the contractor or energy advisor will provide and install up to $250 worth of energy-saving measures in your home at no additional cost" — Delaware Electric Cooperative, Home Energy Audits, retrieved 2026-09-24.”
Our energy expert: The Home Energy Check-Up and Counseling visit is free and is the easiest first move if you are not ready to pay for the full assessment. An advisor walks the house with you, installs a package of small measures on the spot, and explains where your bill is actually going. Book it before you spend money on anything larger — it will tell you whether the house needs air sealing or equipment first.
Residential Electric Vehicle Supply Equipment (EVSE) Rebate
Estimated benefit: Up to 50% of equipment and installation cost for market-rate customers; up to 90% for income-eligible customers. Where the installation needs an electrical panel upgrade, the program covers 50% of the panel-upgrade portion, not to exceed $2,500. Level 2 (208/240 V) hardwired or plug-in chargers only; mobile and portable connectors are not eligible; self-installation is not eligible. One rebate per household account. A Home Performance audit is required, and income-eligible applicants also need a Weatherization Assistance Program audit.
Timing: Program year 1 July 2026 – 30 June 2027, as printed on p. 1. Applications must be submitted within 60 days of the installation date.
“"This program runs from July 1, 2026 through June 30, 2027. … MARKET RATE CUSTOMERS A rebate will be provided for up to 50% of the equipment and installation costs. INCOME ELIGIBLE CUSTOMERS … up to 90% of the equipment and installation costs." (p. 1) and "NOTE: If your installation requires an electrical panel upgrade, we will cover 50% of the panel upgrade portion of the installation costs, not to exceed $2,500." (p. 2) — Electric Vehicle Supply Equipment Rebate Form, June 2026 V12.”
Our energy expert: Energize Delaware's published residential EVSE schedule covers up to 50% of equipment and installation cost for a market-rate customer and up to 90% for an income-eligible household, where the program's conditions are met. If the electrical panel has to be upgraded to carry the circuit, 50% of the panel-upgrade portion counts, not to exceed $2,500. Four conditions catch applicants: the charger must be a fixed Level 2 unit at 208/240 V, so a mobile or portable connector does not qualify; self-installation is not eligible; a Home Performance audit is required, and an income-eligible applicant also needs a Weatherization Assistance Program audit; and the application must be submitted within 60 days of the installation date. One rebate per household account, and this program year runs to 30 June 2027.
Delaware Electric Cooperative 1 program
Home Energy Assessment (delivered through Home Performance with ENERGY STAR®)
Estimated benefit: A home energy audit for $50, with the contractor or energy advisor providing and installing up to $250 worth of energy-saving measures at no additional cost — energy-efficient light bulbs including dimmable, candelabra and globe types; faucet aerators; efficient-flow fixed showerheads; and water-heater pipe insulation on hot and cold pipes for four feet from the water heater, as accessible. Measures identified by the audit then qualify for Energize Delaware's Home Performance rebate schedule.
Timing: Checked 2026-09-24.
“"Did You Know? Delaware Electric Cooperative members can now receive a home energy audit for just $50!" and "During your home's energy assessment, the contractor or energy advisor will provide and install up to $250 worth of energy-saving measures in your home at no additional cost." — Delaware Electric Cooperative, Home Energy Audits, retrieved 2026-09-24.”
Our energy expert: Fifty dollars buys a co-op member a full Home Performance with ENERGY STAR assessment, and the published scope includes up to $250 worth of measures provided and installed at no additional cost during the visit — energy-efficient lamps including dimmable, candelabra and globe types, faucet aerators, an efficient-flow fixed showerhead, and insulation on the hot and cold water-heater pipes for four feet, as accessible. The assessment also feeds the next stage: measures it identifies then qualify for Energize Delaware's Home Performance rebate schedule. Confirm with Energize Delaware which measures and which rebates this audit covers before you commit to the work.
Delmarva Power & Light Company (Delaware) 1 program
ENERGY STAR® New Homes Program — for home buyers
Estimated benefit: No rebate is paid to the home buyer. The benefit is a home certified to the EPA's ENERGY STAR specification, verified by an independent third-party rater, using on average 10 to 20% less energy than a standard new home built to code. The cash rebates in this program are paid to the builder — see the builder row on the commercial tab.
Timing: Checked 2026-09-24.
“"ENERGY STAR certified homes use an average of 10 to 20% less energy than standard new homes built to code." — Delmarva Power, ENERGY STAR® New Homes Program, retrieved 2026-09-24.”
Our energy expert: If you are buying new in Delmarva Power's Delaware territory, ask whether the builder is in Delmarva's ENERGY STAR New Homes program. There is no cheque for you — the rebate goes to the builder — but the certification is worth having, because it is verified by an independent rater rather than claimed on a brochure, and the EPA puts the saving at 10 to 20% against a code-built house. Delmarva publishes a list of participating builders.
Programs for businesses
DNREC Division of Climate, Coastal and Energy 12 programs
Energy Efficiency Investment Fund — Prescriptive Improvement Grants
Estimated benefit: A grant paid per unit installed at the rate set out in the corresponding prescriptive application, up to 60% of energy-efficiency-related costs, whichever is less. Grant awards will not exceed $250,000 per individual address per calendar year. Eligible categories are lighting and lighting controls (Appendix A, pp. 20–21), HVAC and water heating (Appendix B, pp. 22–28) and appliances and food-service equipment (Appendix C, pp. 29–30). Lighting products must be listed on the ENERGY STAR Certified Light Fixtures list or the DesignLights Consortium qualified products list; HVAC and water-heating equipment must exceed 2018 IECC and ASHRAE 90.1-2016 code requirements. DNREC will not pay a prescriptive rate above the final unit price on the itemised invoice.
Timing: Rolling. Funds are limited. Guidelines Version 8.1 effective February 2026; checked 2026-09-24.
“"The grant for a prescriptive project will be paid per unit installed at a rate detailed in the corresponding prescriptive grant pathway application, up to 60% of the energy efficiency related costs, whichever is less." (§5.1.1, p. 8) and "The Fund will not pay more than 60% of the energy efficiency related project cost for any proposed project as detailed on itemized invoices … Grant awards will not exceed $250,000 per individual address per calendar year." (§4.1.4, p. 5) — Energy Efficiency Investment Fund Program Guidelines and Operational Procedures, Version 8.1, effective February 2026.”
Our energy expert: DNREC publishes this fund as open to non-residential, commercial, industrial, local government, governmental and non-profit entities in Delaware that pay the Public Utility Tax, and says it verifies that payment from the utility bills filed with the application — so a manufacturer, a school or a non-profit that pays the tax belongs here, and Energize Delaware runs the parallel fund for Delaware schools, local governments and non-profits that do not. Do not try to settle that from the bill on your own: DNREC notes that some municipal electric companies code the charge under another name, such as 'Commercial Tax' or 'Utility Tax'. The prescriptive path pays a set amount per unit for lighting, HVAC, water heating and commercial kitchen equipment, so the paperwork is an equipment schedule rather than an engineering study. Two ceilings apply — 60% of the efficiency-related cost, and $250,000 per address per calendar year — and DNREC will not pay a prescriptive rate above the final unit price on the itemised invoice, so a deeply discounted fixture earns the discounted price rather than the published rate. Ask DNREC's Division of Climate, Coastal and Energy to confirm you are on its side of the fund before you commission work.
Energy Efficiency Investment Fund — Custom Improvement Grants
Estimated benefit: Electric: $0.20 per kWh at Single Tier, $0.25 per kWh at Multi-Tier, $0.30 per kWh at Comprehensive Tier. Gas: $10 per MMBTU, $20 per MMBTU and $27 per MMBTU on the same tiers. Fuel switch bonus, where a measure replaces a fossil-fuel-fired appliance with an electric alternative: +$2, +$5 and +$8 per MMBTU respectively. Paid up to 60% of energy-efficiency-related costs, whichever is less, and capped at $250,000 per address per calendar year. Tier is set by comprehensiveness: one end use is Single Tier; a building energy management system or two end uses reaches Multi-Tier; three or more end uses reaches Comprehensive Tier. Multi-tier and Comprehensive-tier measures must all be complete and finally approved to be paid at the tier rate. Projects delivering savings solely from retrofit lighting or solely from retro-commissioning are not eligible. Project funds are reserved for 12 months on a first-come, first-served basis, with one 60-day extension available on request.
Timing: Pre-approval required before purchase and installation. Funds reserved for 12 months with one 60-day extension.
“"The grant for a custom application will be paid at the following rates for each tier, up to 60% of energy efficiency related costs, whichever is less. … Electric Incentive: Single Tier $0.20 / kWh, Multi-Tier $0.25 / kWh, Comprehensive Tier $0.30 / kWh. Gas Incentive: $10 / MMBTU, $20 / MMBTU, $27 / MMBTU. *Fuel Switch Bonus: … Single Tier: $2 / MMBTU, Multi-Tier: $5 / MMBTU, Comprehensive Tier: $8 / MMBTU." — EEIF Program Guidelines and Operational Procedures, Version 8.1, February 2026, p. 12.”
Our energy expert: The custom path pays on savings, and the rate rises with how much of the building you touch in one project: $0.20 a kilowatt-hour for a single end use, $0.25 if you add a building energy management system or a second end use, $0.30 for three or more. Gas follows the same ladder at $10, $20 and $27 per MMBTU, with a further $2 to $8 per MMBTU where you replace a fossil-fuel appliance with an electric one. That structure is telling you something worth hearing: three measures done together earn half as much again per unit of savings as the same three done in three separate years. Lighting alone does not qualify for this path, nor does retro-commissioning alone. Get pre-approval before you buy anything — that rule is absolute here.
Energy Efficiency Investment Fund — Energy Assessment Grants
Estimated benefit: The lesser of 50% of the cost of the energy audit, or a cap of $5,000 for a targeted energy audit or $10,000 for a comprehensive energy audit. An additional amount — up to $5,000 for a targeted audit and up to $10,000 for a comprehensive audit — may be available to applicants who then implement measures identified by the assessment AND complete a Prescriptive, Custom or CHP EEIF project; to qualify, the implemented measure grant award must exceed the total energy assessment grant. The assessment application must be submitted within 30 days of audit completion. DNREC limits each facility address or contiguous structure to one paid assessment every calendar year unless ownership or operational use changes. A comprehensive audit must comply with ASHRAE Level II requirements.
Timing: The assessment application must be submitted within 30 days of audit completion. One paid assessment per address per calendar year.
“"If the application is approved, EEIF may award the customer up to the lesser of (1) 50% of the cost of their energy audit or (2) the audit caps of $5,000 for a targeted energy audit or $10,000 for a comprehensive energy audit … An additional amount, up to $5,000 for targeted audits and up to $10,000 for comprehensive" — EEIF Program Guidelines and Operational Procedures, Version 8.1, February 2026, §5.3.1, pp. 14–15.”
Our energy expert: The Energy Efficiency Investment Fund publishes an assessment grant of the lesser of 50% of the audit cost or $5,000 for a targeted audit and $10,000 for a comprehensive one, which must comply with ASHRAE Level II requirements. A second tranche — up to $5,000 targeted, up to $10,000 comprehensive — can be paid where you implement measures the assessment identifies and complete a Prescriptive, Custom or CHP EEIF project, and where the implemented-measure award exceeds the total assessment grant. Two things catch applicants: the assessment application must be submitted within 30 days of the audit being completed, and the assessment grant does not substitute for the separate pre-approval EEIF requires before anything is installed. The program funds one assessment per facility address or contiguous structure per calendar year unless ownership or operational use changes.
Energy Efficiency Investment Fund — Combined Heat and Power Grants
Estimated benefit: $500 per kW of the installed system, up to 60% of energy-efficiency-related costs, whichever is less, and within the $250,000 per address per calendar year cap. Eligible installed costs are limited to genset equipment, associated equipment such as heat recovery jacket, switchgear and absorption chillers, installation, engineering and project management, and decommissioning of pre-existing equipment. Eligible technologies are reciprocating engines, microturbines, steam turbines, gas turbines and fuel cells; professional engineer signatures are required on the design. Equipment must be new, permanently installed, and meet a minimum 60% annual efficiency requirement, producing 1.0 MMBtu per hour of useful thermal output. Incremental expansion of an existing CHP system is eligible, calculated on the expansion rather than total system size. Third-party vendors and power purchase agreements are eligible, with the signed agreement required before payment. Installations must be designed to avoid flood impacts including future sea-level rise, with a flood risk mitigation plan required inside the floodplain.
Timing: Rolling; funds limited.
“"Grants for CHP projects will be paid at a rate of $500/kW of the installed system, up to 60% of the energy efficiency related costs, whichever is less." — EEIF Program Guidelines and Operational Procedures, Version 8.1, February 2026, §5.4.1, p. 17.”
Our energy expert: Five hundred dollars a kilowatt toward combined heat and power, within the usual 60% and $250,000-per-address limits. CHP only makes sense where you run long hours and have a genuine thermal load to absorb the heat — a hospital, a food plant, a hotel, a wastewater works. Delaware sets the technical bar at 60% annual system efficiency and at least 1.0 MMBtu per hour of useful thermal output, which is a real test rather than a formality, and it requires a professional engineer's signature on the design. Two details worth knowing early: expanding an existing CHP system qualifies, calculated on the expansion alone, and a third-party or power-purchase structure is eligible provided the signed agreement is in before payment. If the site is in the floodplain, budget for a flood risk mitigation plan.
Cool Switch Low-Impact Refrigerant Program
Estimated benefit: Paid at $25 per ton of avoided CO2-equivalent emissions, up to the following limits. Retrofit projects: the lesser of 50% of total project cost or $250,000. New natural refrigerant systems: the lesser of 50% of total project cost or $250,000. New conventional systems: the lesser of 25% of total project cost or $250,000. Open to all Delaware non-residential consumers using at least 50 lbs of refrigerant. Installed refrigerants must have a global warming potential below 1,500 — examples given are R-449A, R-448A, ammonia and carbon dioxide. Avoided emissions are calculated from years of remaining system operation, system charge in pounds, and the global warming potential of the existing and replacement refrigerants. All grants require pre-approval before purchasing any services, equipment or refrigerants.
Timing: Rolling. Pre-approval required before purchasing any services, equipment or refrigerants.
“"Incentives for all pathways will be paid at a rate of $25 per ton of avoided CO2 equivalent emissions up to the limits described below: Retrofit System Incentive Limit — All retrofit projects: Lesser of 50% of total project cost or $250,000. New System Incentive Limits — Natural refrigerant systems: Lesser of 50% of total project cost or $250,000. Conventional systems: Lesser of 25% of total project cost or $250,000." — DNREC, Cool Switch Low-Impact Refrigerant Program, retrieved 2026-09-24.”
Our energy expert: Open to any Delaware non-residential consumer using at least 50 lbs of refrigerant — supermarkets, cold stores, ice rinks, food processors. DNREC publishes a rate of $25 per ton of avoided CO2-equivalent emissions, and the avoided figure is calculated from the system's remaining years of operation, its charge in pounds, and the global warming potential of the existing and replacement refrigerants, so those are the numbers to pin down first. Limits differ by route: a retrofit or a new natural refrigerant system can pay the lesser of 50% of total project cost or $250,000, a new conventional system the lesser of 25% or $250,000. The installed refrigerant must have a global warming potential below 1,500 — R-449A, R-448A, ammonia and carbon dioxide are the examples given. Pre-approval is required before you purchase any services, equipment or refrigerants; nothing bought beforehand counts.
Green Energy Program — Photovoltaic Grant (non-residential and non-profit)
Estimated benefit: $0.75 per watt up to 50,000 watts for non-residential applicants, to a maximum grant of $40,000; $0.85 per watt for a certified diverse business, to a maximum of $45,000; $0.90 per watt for a non-profit, to a maximum of $50,000. Notes printed on the same sheet: incentives apply to Delmarva Power and Light customers only; applications submitted more than 12 months after installation completion are ineligible; no grant may exceed 50% of total project cost; total project cost must be $6.00 per watt or less; a Solar Shade Analysis showing a Total Solar Resource Fraction of 70% or greater is required. Applicants must sign their Solar Renewable Energy Credits over to the Delaware Sustainable Energy Utility and register as an eSupplier with Delaware's Division of Accounting before payment.
Timing: No closing date. Applications more than 12 months after installation completion are ineligible.
“"Photovoltaic grants ($/Watt) — Non-Residential: Up To 50,000 Watts $0.75, Maximum Grant $40,000. Certified Diverse Business: $0.85, Maximum Grant $45,000. Non-Profit: $0.90, Maximum Grant $50,000." — Green Energy Program Incentives, DNREC, effective July 1, 2026, p. 1.”
Our energy expert: The Green Energy Program publishes three non-residential solar rates: $0.75 per watt up to 50,000 watts to a maximum grant of $40,000 for a standard applicant, $0.85 per watt to a maximum of $45,000 for a certified diverse business, and $0.90 per watt to a maximum of $50,000 for a non-profit. If your organization may hold either status, get the certification in place before you apply, because the published rate follows the class. The standard conditions apply: Delmarva Power and Light customers only, no grant above 50% of total project cost, installed price of $6.00 per watt or less, a Solar Shade Analysis showing a Total Solar Resource Fraction of 70% or greater, and your Solar Renewable Energy Credits signed over to the Delaware Sustainable Energy Utility. Apply within 12 months of installation completion.
Green Energy Program — Solar Canopy Grant
Estimated benefit: $1.00 per watt, to a maximum grant of $100,000, for non-residential and non-profit applicants. This rebate cannot be combined with the standard non-residential solar incentive. Eligibility is determined by the existing Green Energy Program guidelines for solar applications. Notes printed on the same sheet: incentives apply to Delmarva Power and Light customers only; applications submitted more than 12 months after installation completion are ineligible; no grant may exceed 50% of total project cost; total project cost must be $6.00 per watt or less; a Solar Shade Analysis showing a Total Solar Resource Fraction of 70% or greater is required. Applicants must sign their Solar Renewable Energy Credits over to the Delaware Sustainable Energy Utility and register as an eSupplier with Delaware's Division of Accounting before payment.
Timing: Launched August 2026.
“"Solar Canopy & Brownfield Grants ($/Watt) — Solar Canopy $1.00, Maximum Grant $100,000." — Green Energy Program Incentives, DNREC, effective July 1, 2026, p. 1. And: "Nonresidential (commercial and nonprofit) entities are eligible for rebates up to $100,000 for the installation of solar canopies. … This rebate cannot be combined with the current incentive for nonresidential solar." — DNREC, Green Energy Program, retrieved 2026-09-24.”
Our energy expert: New since August 2026: the Green Energy Program publishes a solar canopy rate of $1.00 per watt, to a maximum grant of $100,000, for non-residential and non-profit applicants. A canopy costs more to build than a roof array because it carries its own structure, and the higher published rate sits against that. It suits a business with a large car park and a roof that cannot take the load. You cannot combine this with the standard non-residential solar incentive on the same array, so price both routes before you choose. The Green Energy Program's standard conditions apply: Delmarva Power and Light customers only, no grant above 50% of total project cost, installed price of $6.00 per watt or less, a Solar Shade Analysis showing a Total Solar Resource Fraction of 70% or greater, and your Solar Renewable Energy Credits signed over to the Delaware Sustainable Energy Utility.
Green Energy Program — Solar on Brownfields Grant
Estimated benefit: $1.00 per watt, to a maximum grant of $100,000, for non-residential and non-profit applicants. The site must be a certified brownfield and must meet the Green Energy Program's existing guidelines for solar applications. This rebate cannot be combined with the standard non-residential solar incentive. Notes printed on the same sheet: incentives apply to Delmarva Power and Light customers only; applications submitted more than 12 months after installation completion are ineligible; no grant may exceed 50% of total project cost; total project cost must be $6.00 per watt or less; a Solar Shade Analysis showing a Total Solar Resource Fraction of 70% or greater is required. Applicants must sign their Solar Renewable Energy Credits over to the Delaware Sustainable Energy Utility and register as an eSupplier with Delaware's Division of Accounting before payment.
Timing: Launched August 2026.
“"Solar Canopy & Brownfield Grants ($/Watt) — Solar on Brownfields $1.00, Maximum Grant $100,000." — Green Energy Program Incentives, DNREC, effective July 1, 2026, p. 1. And: "To be eligible, the site must be a certified brownfield and meet the Green Energy Program's existing guidelines for solar applications." — DNREC, Green Energy Program, retrieved 2026-09-24.”
Our energy expert: The Green Energy Program publishes a rate of $1.00 per watt, to a maximum grant of $100,000, for solar on a certified brownfield — land that is hard to use for anything else and cheap for that reason. Certification has to be in place first. The site must also meet the Green Energy Program's existing guidelines for solar applications, and you cannot combine this with the standard non-residential solar incentive. The usual conditions hold: Delmarva Power and Light customers only, no grant above 50% of total project cost, installed price of $6.00 per watt or less, a Solar Shade Analysis at a Total Solar Resource Fraction of 70% or greater, and Solar Renewable Energy Credits signed over to the Delaware Sustainable Energy Utility.
Solar + Storage Pilot Program — commercial and non-profit battery grant
Estimated benefit: $200 per kWh for commercial applicants, to a maximum grant of $30,000; $225 per kWh for a certified diverse business, to a maximum of $35,000; $250 per kWh for a non-profit, to a maximum of $40,000. No hardware size cap. No grant may exceed 50% of the total eligible storage cost. Applicant must be a Delmarva Power electric customer; the battery must be behind the meter at the installation address, owned by the applicant, and must have received final interconnection approval from Delmarva Power no more than one year before application. The battery must carry at least a 10-year manufacturer warranty, must be capable of islanding during outages, and must be enrolled with Delmarva Power in an active dispatch program for 10 years once that is available. The equipment supplier must maintain rated power capacity for the 10-year service life to an availability standard above 75%, and decommissioning is the contractor's or third-party owner's responsibility.
Timing: Interconnection approval must be less than 12 months old at application.
“"Battery Storage Grants ($/kWh) — Commercial: Incentive Rates $200 per kWh, Maximum Grant $30,000. Certified Diverse Business: $225 per kWh, Maximum Grant $35,000. Non-Profit: $250 per kWh, Maximum Grant $40,000. Hardware Size Cap: None." — Solar + Storage Pilot Program Guidelines and Incentives, DNREC, effective August 11, 2026, p. 1.”
Our energy expert: The Solar + Storage pilot publishes commercial battery rates of $200 per kWh to a maximum grant of $30,000, $225 per kWh to a maximum of $35,000 for a certified diverse business, and $250 per kWh to a maximum of $40,000 for a non-profit — never more than 50% of eligible storage cost. You must be a Delmarva Power electric customer, own the battery, and site it behind the meter at the installation address. Final interconnection approval must be less than twelve months old at application, so this belongs in the same program of work as the solar rather than a later addition. The battery is then committed to Delmarva's dispatch program for ten years once that exists, with rated power capacity held to an availability standard above 75% and decommissioning the contractor's or third-party owner's responsibility. Read that obligation against how you intend to operate the battery yourself.

Estimated benefit: Standard multi-family: 75% of the charging station cost, 75% of eligible installation costs, or 80% of eligible installation costs where the installation is future-proofed. Priority Area multi-family: 90% of the charging station cost, 85% of eligible installation costs, or 90% where future-proofed. The maximum rebate is $5,000 for single-port chargers and $10,000 for dual-port chargers, with a limit of $75,000 per site including stations and installation. $2 million is available program-wide on a first-come, first-served basis; recipients must fund the work and be reimbursed. Only AC Level 2 stations purchased and installed after 1 May 2026 are eligible. A Priority Area is a census tract identified by the Delaware Department of Transportation as an Equity Focus Area or by the EPA as an Environmental Justice Area of Exceedance. Apartments and condominiums must have four or more residential units.
Timing: Stations must be purchased and installed after 1 May 2026. $2 million available, first come first served.
“"Multi-Family Dwellings: Charging Station Rebate 75%, Installation Reimbursement 75%, Installation Reimbursement with Future Proofing 80%. Priority Area Multi-Family Dwellings: 90%, 85%, 90%." and "The maximum rebate for multi-family projects is $5,000 for single-port chargers and $10,000 for dual-port chargers. The limit is $75,000 maximum per site, including charging station(s) and installation costs." — DNREC, Electric Vehicle Charging Equipment Rebates, retrieved 2026-09-24.”
Our energy expert: For apartments or condominiums of four or more units, DNREC's published multi-family schedule covers 75% of the charging station cost and 75% of eligible installation costs, rising to 80% of installation where the work is future-proofed. In a Priority Area — a census tract DelDOT identifies as an Equity Focus Area or the EPA as an Environmental Justice Area of Exceedance — the published rates are 90% of the station cost and 85% of installation, or 90% where future-proofed. Check which tract the property sits in before you assume. Caps are $5,000 for single-port chargers, $10,000 for dual-port, and $75,000 per site including stations and installation, against $2 million program-wide on a first-come, first-served basis. Only AC Level 2 stations purchased and installed after 1 May 2026 qualify, and this is a reimbursement — you fund the work and claim afterwards.
Electric Vehicle Charging Equipment Rebates — public access, fleet and workplace
Estimated benefit: Commercial purchasers: 75% of the charging station cost and 75% of eligible installation costs. Government and non-profit purchasers: 90% of the charging station cost and 85% of eligible installation costs. Maximum $5,000 per charging station port, with a limit of 10 charging ports (or 5 dual-port stations) per location. Three project categories qualify: Public Access — stations open to the public at retail centers, park and rides, hospitals, schools and universities, downtown areas, parking garages, hotels, parks and attractions; Workplace — stations installed to give employees free or low-cost charging, which need not be open to the public; and Fleet — stations dedicated to workplace fleet vehicles owned by a commercial, non-profit or government entity. Only AC Level 2 stations are eligible; Level 1 and DC fast charging are excluded. Rebates for single-family home charging are not offered under this program.
Timing: Stations must be purchased and installed after 1 May 2026. Pre-approval application required.
“"Rebate Amounts and Limits (Max: $5,000 per port; up to 10 charging ports per location) — Public Access / Workplace / Fleet: Commercial Charging Station Rebate 75% of the cost, Installation Reimbursement 75% of eligible costs; Government and Nonprofit Charging Station Rebate 90% of the cost, Installation Reimbursement 85% of eligible costs. Limit Per Location: 10 charging ports (or 5 dual-port stations) per location." — Public Access, Fleet and Workplace Charging Station Rebate Program Guidelines, DNREC, May 1, 2026 – FR8, Table 1, p. 2.”
Our energy expert: DNREC's public access, workplace and fleet schedule publishes 75% of the charging station cost and 75% of eligible installation costs for a commercial purchaser, and 90% of the station cost with 85% of installation for a government body or a non-profit. The ceiling is $5,000 per charging port, with a limit of 10 charging ports — or 5 dual-port stations — per location. Two points get missed. Workplace charging does not have to be open to the public to qualify, and stations dedicated to a fleet count as well. And only AC Level 2 is eligible: Level 1 and DC fast charging are excluded, so a rapid charger earns nothing here. Single-family home charging falls outside this program. Stations must be purchased and installed after 1 May 2026, and a pre-approval application has to be in before you buy.
Electric Vehicle Charging Equipment Rebates — government and non-profit rate
Estimated benefit: 90% of the charging station cost and 85% of eligible installation costs, against 75% and 75% for a commercial purchaser. Maximum $5,000 per charging station port, up to 10 ports (or 5 dual-port stations) per location. Available across all three project categories — public access, workplace and fleet. Only AC Level 2 stations qualify.
Timing: Stations must be purchased and installed after 1 May 2026.
“"Delaware nonprofit organizations and government-entity purchasers of public-access charging stations are eligible for rebates of up to 90% of charging-station costs and up to 85% of installation costs." — Public Access, Fleet and Workplace Charging Station Rebate Program Guidelines, DNREC, May 1, 2026 – FR8, p. 2.”
Our energy expert: A Delaware town, school district, library or non-profit gets a better deal on EV charging than a business does: 90% of the hardware and 85% of the installation, against 75% and 75%. At $5,000 a port and up to ten ports per site, a municipal car park or a school bus depot can be most of the way to fully funded. Three categories qualify and they are broader than they sound — public access includes schools, universities, hospitals, parks and downtown parking; workplace covers staff-only charging; fleet covers depot charging for vehicles you own. Level 2 only; a DC fast charger earns nothing. Get the pre-approval application in before you order anything.
Energize Delaware (Delaware Sustainable Energy Utility) 8 programs
Rural Energy Advancement Grant (REAG)
Estimated benefit: Covers up to 25% of the business's Energize Delaware Low-Interest Commercial Loan amount, capped at $250,000. Approval of the grant depends on approval of the loan. The grant is paid once the project is complete, all loan draws are taken and the loan is in repayment. Open to rural businesses that have not received or been accepted into the USDA Rural Energy for America Program grant; eligibility for 'rural' is set by USDA's Terms and Eligibility Map.
Timing: Interest form open on the page as at 2026-09-24.
“"For rural businesses that have not received or been accepted into the USDA REAP Grant. Grant for energy efficiency, solar, or combination projects. Covers up to 25% of your total Energize Delaware Low-Interest Commercial Loan amount. Capped at $250,000. Grant approval is contingent on loan approval." — Energize Delaware, Business → Grants & Rebates, retrieved 2026-09-24.”
Our energy expert: If your business is rural by USDA's map and USDA's own REAP grant has not come through, Energize Delaware will put up a grant worth a quarter of the low-interest commercial loan you take for the project, to a ceiling of $250,000. The order matters: the loan has to be approved first, and the grant is not paid until the work is finished, the draws are taken and you are making loan payments. Treat it as a rebate on the cost of borrowing rather than money you can spend during construction.
Affordable Multifamily Housing — Existing Building Initiative
Estimated benefit: Energy assessment, project scoping and incentives toward efficiency and renewable measures in existing affordable multifamily buildings, with Energize Delaware financing available for the balance. Per-measure incentive amounts not yet confirmed from an Energize Delaware document.
Timing: Enrollment form dated March 2026 was live as at 2026-09-24.
“"Helps owners of affordable multifamily properties identify, plan, and implement energy-efficiency and renewable-energy improvements through technical assistance, incentives, and financing." — Energize Delaware, Affordable Housing, retrieved 2026-09-24.”
Our energy expert: Own affordable multifamily property in Delaware and this initiative is the route to the engineering work before you commit capital — an energy assessment, project scoping, then incentives toward efficiency and renewable measures, with Energize Delaware financing available for the balance. We could not confirm per-measure incentive amounts from an Energize Delaware document as at 24 September 2026, so treat them as set project by project and ask for them in writing before you sign a contractor. The enrollment form on the program page was dated March 2026 and live when we checked. Any financing is subject to credit approval and the program rules in force at application; confirm current terms with Energize Delaware before contracting.
Affordable Multifamily Housing — New Construction / Gut Rehab Initiative
Estimated benefit: Support for energy-efficient new construction and gut rehabilitation of affordable multifamily housing. Incentive amounts not yet confirmed from an Energize Delaware document.
Timing: Flyers dated March 2026; checked 2026-09-24.
“"Affordable Multifamily Housing — Helps owners of affordable multifamily properties identify, plan, and implement energy-efficiency and renewable-energy improvements through technical assistance, incentives, and financing." — Energize Delaware, Affordable Housing, retrieved 2026-09-24.”
Our energy expert: If you are building or gut-rehabbing affordable multifamily housing in Delaware, bring Energize Delaware in at design, not at handover. The program is built around getting the envelope and the systems right while the drawings can still change, and it carries incentives and financing for the difference in cost. Ask the program for the current incentive schedule in writing at the first meeting.
Business Technical Assistance Program
Estimated benefit: No-cost technical support for owners of commercial and nonprofit buildings of 10,000–50,000 sq ft and their contractors. Produces an EPIC-generated report estimating annual and lifetime energy savings, greenhouse-gas reduction and the effect on operating income. Qualifying upgrades identified through it may then be eligible for Energize Delaware low-cost long-term commercial loans and cash incentives.
Timing: Checked 2026-09-24.
“"Energize Delaware's Business Technical Assistance Program offers no-cost support to owners of mid-size commercial and nonprofit buildings (10,000–50,000 sq. ft.) and their energy efficiency contractors." — Energize Delaware, Business → Energy Assessments, retrieved 2026-09-24.”
Our energy expert: If you own a commercial or nonprofit building between 10,000 and 50,000 square feet, Energize Delaware publishes this technical support as no-cost to owners in that size range and to their contractors. The team models the upgrade you are weighing — an HVAC replacement, a lighting retrofit, rooftop solar — and returns an EPIC-generated report estimating annual and lifetime energy savings, greenhouse-gas reduction and the effect on operating income. It fits two moments in particular: when the HVAC is near the end of its life and electrification is on the table, and when the roof is being replaced and solar could go on at the same time. Qualifying upgrades identified through it may then be eligible for Energize Delaware's low-cost long-term commercial loans, which are subject to credit approval, and its cash incentives. Confirm eligibility with Energize Delaware before contracting.
Energy Efficiency Investment Fund for Non-Profits — Prescriptive Improvement Grants
Estimated benefit: Set rebates per unit for qualifying lighting, HVAC, natural-gas heating and water heating, and food-service and refrigeration equipment, paid after installation. The fund will not pay more than 60% of total project cost, and grants are capped at $250,000 per individual address per calendar year. Open only to Delaware schools, local governments and non-profits that do not pay the 4.25% Public Utility Tax on their electricity or gas.
Timing: Rolling while funds last.
“"The Fund will not pay more than 60% of the total project cost for any proposed project as detailed on itemized invoices." — EEIF for Non-Profits Application Form, October 2025 V3, p. 2, term 10. And: "The EEIF for Non-Profits program will not pay more than 60% of the energy efficiency related project costs for any proposed project up to $250,000 per individual address per calendar year, whichever is less." — Energize Delaware, Public & Non-Profit → Grants & Rebates, retrieved 2026-09-24.”
Our energy expert: Delaware splits this money by who pays the Public Utility Tax, not by what kind of organization you are: DNREC's fund is open to non-residential, commercial, industrial, local government, governmental and non-profit entities that pay the tax, and this is the parallel fund for Delaware schools, local governments and non-profits that do not. Do not try to settle which side you are on from the bill — DNREC notes that some municipal electric companies code the charge under another name, such as 'Commercial Tax' or 'Utility Tax', so the bill will not reliably tell you. The prescriptive path pays set amounts per unit for lighting, HVAC, water heating and commercial kitchen equipment. Two ceilings apply: 60% of project cost, and $250,000 per address per calendar year. Have Energize Delaware confirm which of the two funds you belong to before you commission work — the wrong call sends your application to the wrong administrator and costs you the time it takes to find out.
Energy Efficiency Investment Fund for Non-Profits — Custom Improvement Grants
Estimated benefit: Paid on calculated savings: Single Tier $0.20/kWh or $10/MMBTU; Multi-Tier $0.25/kWh or $20/MMBTU; Comprehensive Tier $0.30/kWh or $27/MMBTU. A fuel-switch bonus adds $2, $5 or $8 per MMBTU respectively where an electric alternative replaces a fossil-fuel-fired appliance. Tier is set by comprehensiveness: one end use is Single Tier; a building energy management system or two end uses reaches Multi-Tier; three or more end uses reaches Comprehensive Tier. Capped at 60% of energy-efficiency-related cost or $250,000 per address per calendar year, whichever is less. Retrofit-lighting-only projects and retro-commissioning-only projects are not eligible for the custom path.
Timing: Rolling. Custom projects must be approved before purchase and installation.
“"EEIF for Non-Profits Custom Incentive — Electric: Single Tier $0.20/kWh, Multi-Tier $0.25/kWh, Comprehensive Tier $0.30/kWh. Gas: $10/MMBTU, $20/MMBTU, $27/MMBTU. Fuel switch bonus: +$2/MMBTU, +$5/MMBTU, +$8/MMBTU." — Energize Delaware, Public & Non-Profit → Grants & Rebates, custom incentive tier chart, retrieved 2026-09-24.”
Our energy expert: The custom path pays on savings rather than on equipment, and the rate climbs with how much of the building you touch. One end use earns $0.20 per kWh saved; add a building energy management system or a second end use and it is $0.25; three or more end uses and it is $0.30. Gas runs $10, $20 and $27 per MMBTU on the same ladder, with another $2 to $8 per MMBTU where you replace a fossil-fuel appliance with an electric one. That structure rewards doing the building in one pass rather than in three separate years. Custom projects must be approved before anything is bought — approval after the fact is not available on this path.
Solar for School Districts Grant
Estimated benefit: Grant funding toward feasibility studies, installation, array components and the cost of utility upgrades for ground, roof or carport-mounted solar. Grants stay active for 24 months after funding is allocated and the grant is approved. Grant amount not yet confirmed from an Energize Delaware document.
Timing: Grant life 24 months from approval.
“"Schools may use grants for feasibility studies, installation, array components, and the cost of utility upgrades. … Grants will be active for a period of 24 months after the funding has been allocated and the grant has been approved by Energize Delaware." — Energize Delaware, Public & Non-Profit → Grants & Rebates, retrieved 2026-09-24.”
Our energy expert: Delaware public school districts can apply for grant funding toward solar — the feasibility study, the array components, the installation, and the utility upgrades that usually derail the budget — for ground, roof or carport-mounted systems. Ask Energize Delaware two things before you budget: whether the district has to be in its Performance Contracting Program, and whether a feasibility study must accompany the application. Once funding is allocated and the grant approved, it stays active for 24 months, which in school-construction terms means procurement starts in the same year. We could not confirm a published grant amount from an Energize Delaware document as at 24 September 2026, so confirm the amount and the application route with Energize Delaware before a budget is committed.
Solar for Non-Profits and Public Libraries Grant
Estimated benefit: Grant funding toward feasibility studies, installation, array components and the cost of utility upgrades for new ground, roof or carport-mounted solar. For new projects only, not existing ones. Grants stay active for six months after funding is allocated and the grant is approved; extensions need pre-approval. Grant amount not yet confirmed from an Energize Delaware document.
Timing: Application portal not open as at 2026-09-24.
“"This is for NEW projects, not existing ones. Nonprofits may use grants for feasibility studies, installation, array components, and the cost of utility upgrades. … Grants will be active for a period of 6 months after the funding has been allocated and the grant has been approved by Energize Delaware. … Application portal coming soon." — Energize Delaware, Public & Non-Profit → Grants & Rebates, retrieved 2026-09-24.”
Our energy expert: Energize Delaware's program documents describe grant funding for non-profits and public libraries toward a feasibility study, array components, installation and the cost of utility upgrades, for new ground, roof or carport-mounted solar only — not an existing array. The documents also describe a grant that stays active for six months after funding is allocated and the grant approved, with extensions needing pre-approval. When we checked on 24 September 2026 the application portal was not open, and we could not confirm a grant amount from an Energize Delaware document. Confirm with Energize Delaware that the program is running, and on what terms, before your board spends anything on it.
Delmarva Power & Light Company (Delaware) 3 programs
ENERGY STAR® New Homes Program — builder rebates
Estimated benefit: Per certified home: single family $1,200 (ENERGY STAR V3.1), $1,900 (V3.2) or $3,900 (ENERGY STAR NextGen All-Electric); townhouse or duplex $700 / $1,350 / $3,350; two-on-two condo $500 / $550 / $2,550; multifamily $350 / $550 / $2,550. Homes must be certified to V3.2 with 100% LED installation to qualify for the listed amounts. Additive bonuses: heat pump water heater above 3.0 UEF +$1,000; heat pump above 15.2 SEER2 and 8.5 HSPF2 +$450; air conditioner above 15.2 SEER2 +$200; ENERGY STAR smart thermostat +$75, up to four per home. The NextGen All-Electric amount cannot be combined with other additive measures.
Timing: Handout dated 01/2026; checked 2026-09-24.
“"Housing Type / Rebate Amount: Single family — V3.1 $1,200, V3.2 $1,900, ENERGY STAR NextGen All-Electric $3,900. Townhouse/Duplex — $700, $1,350, $3,350. Two-on-two condo — $500, $550, $2,550. Multifamily — $350, $550, $2,550. Optional Upgrades: Heat pump water heater, > 3.0 UEF +$1,000; Heat pump, >15.2 SEER2, >8.5 HSPF2 +$450; Air conditioner, > 15.2 SEER2 +$200; ENERGY STAR smart thermostat (up to four per ENERGY STAR new home) +$75." — ENERGY STAR New Homes Builder Benefits, Delmarva Power & Light Company, 01/2026, p. 1.”
Our energy expert: Build to ENERGY STAR in Delmarva Power's Delaware territory and the rebate follows the certification level, not the square footage. A single-family house is worth $1,200 at Version 3.1, $1,900 at Version 3.2, and $3,900 if it meets ENERGY STAR NextGen All-Electric. Townhouses and duplexes run $700, $1,350 and $3,350 on the same ladder. Equipment adds to it — $1,000 for a heat pump water heater above 3.0 UEF, $450 for a qualifying heat pump, $75 per smart thermostat up to four — but the NextGen amount is exclusive and cannot be stacked with those. Two details decide the money: certification to V3.2 with 100% LED lighting, and getting the rater engaged before framing rather than after.
Business Energy Manager
Estimated benefit: Free access to an online tool for tracking and managing the account's energy use. No cash incentive attaches to it.
Timing: No deadline.
“"Business Energy Manager — Take control of your energy use and help manage costs." And: "Online Energy Management (EPO) is no longer available. Please use signup or log in to Business Energy Manager (EPO) to support your energy usage inquiry and find ways to save." — Delmarva Power, Ways to Save → For Your Business → Delaware, retrieved 2026-09-24.”
Our energy expert: This is a tool, not a cheque. Business Energy Manager gives Delmarva Power business customers a view of their own consumption data, which is the cheapest starting point for any efficiency case — you cannot argue for a capital project without a baseline. It replaces the old Online Energy Management (EPO) tool, so old bookmarks will not work.
Switch to Gas (Business)
Estimated benefit: The business Ways-to-Save tile states rebates are available on the installation of qualified high-efficiency furnaces and boilers. The rebate amount and its conditions were not confirmed from a Delmarva Power document in this pass — see the QA tab for the exact pages walked.
Timing: Checked 2026-09-24.
“"Switch to Gas (Business) — Get rebates on the installation of qualified, high-efficiency furnaces and boilers." — Delmarva Power, Ways to Save → For Your Business → Delaware, retrieved 2026-09-24.”
Our energy expert: Delmarva Power's Delaware business pages point to rebates for converting to high-efficiency gas furnaces and boilers. Call the gas engineering team on 302-429-3290 and ask for the current rebate schedule in writing before you order equipment — the amounts are not on the page the link takes you to.
Chesapeake Utilities — Delaware Division 2 programs
Delaware Multifamily Natural Gas Incentive Program
Estimated benefit: A contribution toward the cost of installing gas piping and venting inside the building, offered at the company's sole discretion where its internal rate-of-return model shows the anticipated revenues warrant an investment greater than the cost of the main extension and service connection. The contribution may not exceed 50% of the net present value of savings from the project, and may not in any event exceed the actual cost of installing gas pipe and venting in the premises. Chesapeake Utilities applies an aggregate cap of $250,000 on all such contributions per calendar year. A project qualifies as multifamily if there are at least four individually metered dwelling units in one premises. The customer bears all responsibility for proper installation and maintenance of pipe beyond the company's meter.
Timing: No application window. The aggregate cap resets each calendar year, so the practical deadline is whenever the $250,000 is committed.
“"the contribution provided by the Company may not exceed 50% of the net present value of savings from a project and, in any event, may not exceed the actual cost for installation of gas pipe and venting in the premise. … The Company has an aggregate cap on all such contributions of $250,000 per calendar year. A project will be determined to be a multi-family project if there are at least four (4) individually metered dwelling units in one premise." — Chesapeake Utilities of Delaware, Inc., P.S.C. Del. No. 5, Original Sheet No. 6.152, Rules and Regulations, issue and effective date 15 October 2025, Order No. 10851 in Docket No. 24-0906, p. 31 of the consolidated Delaware tariff posted August 2026.”
Our energy expert: If you are building or converting a multifamily property of four or more individually metered units in Chesapeake Utilities' Delaware territory, the company can contribute toward the internal gas piping and the appliance venting — the costs that usually make a gas conversion uneconomic mid-project. The contribution is discretionary and capped three ways: at half the net present value of the project's savings, at the actual cost of the pipe and venting, and at $250,000 across all such contributions company-wide in a calendar year. That last cap is the one to plan around, because it is shared: get the conversation started early in the year and early in design. Ask for the rate-of-return analysis in writing, because that model is what decides whether the contribution is offered at all.
Natural Gas Vehicle Incentives and Grants (assistance service)
Estimated benefit: Assistance in determining eligibility for tax credits, grants, incentives or other funding opportunities to help offset the purchase price of new natural gas vehicles. No Chesapeake Utilities incentive amount is offered on this page; the company also operates a compressed natural gas fuelling station in Dover.
Timing: No deadline. Page last stamped 7 February 2023; checked 2026-09-24.
“"When considering commercial natural gas vehicles (NGVs), Chesapeake Utilities can assist you in determining your eligibility for tax credits, grants, incentives or other funding opportunities to help offset the purchase price of new NGVs." — Chesapeake Utilities, Commercial → Natural Gas Vehicles → Natural Gas Vehicle Incentives & Grants, retrieved 2026-09-24. Page timestamp on the same URL reads 2023-02-07.”
Our energy expert: Chesapeake Utilities does not pay for a natural gas vehicle, but it will help you work out who does — tax credits, grants and other funding you might qualify for — and it runs a compressed natural gas fuelling station in Dover. Treat this as a phone call to make while you are pricing a fleet conversion, not as money on the table.
Delaware Electric Cooperative 2 programs
Commercial and Industrial LED Lighting Grant
Estimated benefit: A prescriptive grant with a pre-determined amount per fixture type, capped at $25,000 per member. Available to non-residential General Service and Large Commercial members taking distribution and supply service from the co-op. Equipment must carry a full five-year warranty against component failure, malfunction and premature output degradation, covering parts and — for professionally installed systems — the labor to remove and replace defective components. Grants are not provided for energy use above the member's average annual consumption, calculated from the prior two years. Funding is allocated within the calendar year and is not held over.
Timing: Calendar-year 2026 funding, rolling and first come first served. Applications not awarded in 2026 are not held until the next year.
“"The program incentive is prescriptive and has a pre-determined grant amount per fixture type. The maximum grant per member will be capped at $25,000." — 2026 LED Lighting Grant Program Application, Delaware Electric Cooperative, revised December 2025, p. 1.”
Our energy expert: Up to $25,000 per member toward an LED retrofit, paid at a set rate per fixture type rather than on calculated savings — which means the paperwork is an inventory, not an engineering study. Download the Supplemental Existing Lighting Systems Inventory workbook with the application and fill it in from a walk of the building; that spreadsheet is what the grant is calculated from. Two conditions bite: a full five-year warranty on parts and labor, and a cap tied to your own average consumption over the prior two years, so you cannot claim for lighting a load you do not have.
Irrigation System Conversion Grant
Estimated benefit: 30% of the total non-utility cost of converting an irrigation pump from diesel to electric. Eligible costs are parts and labor for installing the electric motor and starter, removing the existing gear head and components, and electrician services. Systems must have a minimum 40 kW load. Approval under the DEC Irrigation System Grant Program is a prerequisite for the non-utility grant.
Timing: Checked 2026-09-24.
“"Grants are available to Delaware Electric Cooperative members for conversion of the irrigation pumps from diesel to electric. The grant provides 30% of the total non-utility cost of the conversion. … Systems which have a minimum of 40kW load are eligible for program funding." — Irrigation System Conversion Grant Program application, p. 1. And: "The grant covers 30% of the total non-utility cost of the conversion. … Eligibility: Systems with a minimum load of 40 kW qualify for funding." — Energize Delaware, Farm → Grants & Rebates, retrieved 2026-09-24.”
Our energy expert: For a Delaware farm still running irrigation off diesel, the co-op will put up 30% of the non-utility cost of going electric — the motor and starter, pulling the old gear head, and the electrician. Your pump needs to be at least 40 kW. The order is the thing people get wrong: you have to be approved under the co-op's own irrigation grant first, and only then does the non-utility grant application go in. The money behind it is the State of Delaware's Energy Efficiency Investment Fund, delivered through the co-op.
Efficiency Smart, for DEMEC member municipal electric utilities 2 programs
Efficiency Smart Small Business Solutions
Estimated benefit: Financial incentives on qualifying upgrades including lighting and lighting controls, refrigeration, HVAC, compressed air systems and motor controls, plus free customised recommendations from an Efficiency Smart account manager. Eligibility: businesses using less than 250,000 kWh a year, or with less than approximately $25,000 in annual electric costs, across all locations. Pre-approval is required before any equipment is ordered. Per-measure amounts not yet confirmed from an Efficiency Smart document.
Timing: The bonus LED incentive is time-limited.
“"To qualify for financial incentives, pre-approval is required before ordering any equipment. Businesses that use less than 250,000 kWh (or have less than approximately $25,000 in annual electric costs) across all locations are eligible." — Efficiency Smart, Small Business Solutions (Newark, Delaware), retrieved 2026-09-24.”
Our energy expert: If your business is in one of the nine Delaware municipal electric territories and uses under 250,000 kWh a year — roughly $25,000 of electricity across all your sites — Efficiency Smart will put an account manager on your project for nothing and pay incentives on lighting, refrigeration, HVAC, compressed air and motor controls. The rule that costs people money is the first one: pre-approval before you order anything. An invoice dated before the approval is an invoice you pay in full. Ring the account manager named on your community's page before you take a quote to a supplier.
Efficiency Smart Large Business Solutions
Estimated benefit: Advice and incentives to help larger businesses save energy and reduce operating costs. Open to customers using more than 250,000 kWh annually across all locations. Developers and landlords seeking project incentives on multifamily property must apply through this program rather than through the residential rebate schedule. Incentive amounts not yet confirmed from an Efficiency Smart document.
Timing: Checked 2026-09-24.
“"Do you use more than 250,000 kWh annually across all locations? View our Large Business Solutions program instead." — Efficiency Smart, Small Business Solutions (Newark, Delaware), retrieved 2026-09-24. And: "Rebates are only available to individual homeowners and renters. Developers and landlords interested in receiving project incentives must apply through the Large Business Solutions program." — Efficiency Smart, Home Energy Rebates, retrieved 2026-09-24.”
Our energy expert: Above 250,000 kWh a year across your sites, Efficiency Smart moves you out of the small-business track and into custom work — engineering advice and project incentives sized to what the measures actually save. This is also the door for landlords and developers: the appliance rebates on the residential schedule are closed to you, and multifamily project incentives come through here instead. Ask for the incentive structure in writing at the first meeting.
Programs for homes & businesses
Delaware Electric Cooperative 6 programs
Heat Pump Water Heater Rebate
Estimated benefit: $300 rebate on an ENERGY STAR qualified heat pump water heater. Available for new construction or for replacement of an existing water heater. The installed location must be served by Delaware Electric Cooperative. The unit must be installed to the manufacturer's specifications. Rebates are subject to approval and to available funding, and the program may end without notice once allocated funds are committed.
Timing: Must be purchased and installed by 31 December 2026. Application must be received within 60 days of the purchase date.
“"Delaware Electric Cooperative is offering a $300 rebate on ENERGYSTAR® qualified heat pump water heaters, which can be two to three times more efficient than traditional electric water heaters." (p. 1) and "Must be purchased and installed by December 31, 2026. … The rebate application must be received within 60 days of the heat pump water heater purchase date." (p. 2) — Heat Pump Water Heating Rebate Application, Delaware Electric Cooperative, revised December 2025.”
Our energy expert: Delaware Electric Cooperative pays $300 toward an ENERGY STAR heat pump water heater, on a replacement or a new build. Two dates decide whether you get it: the unit has to be bought and installed by 31 December 2026, and the application has to reach the co-op within 60 days of the purchase date — which is the one people miss, because the 60 days runs from purchase, not from installation. Before you commit, check the space: a heat pump water heater needs about 1,000 cubic feet of air around it and drops cool, dry air into the room, so a tight utility closet is the wrong place for one.
High Efficiency Air Source Heat Pump Grant
Estimated benefit: Class A members (average monthly peak demand under 50 kW): $500 per ton up to $1,500 per dwelling at 18.0 SEER2 or better; $750 per ton up to $2,250 at 20.0 SEER2; $1,000 per ton up to $3,000 at 22.0 SEER2. Class B members (50 kW or more): $500 per ton up to $5,000 at 16.0 IEER2; $750 per ton up to $7,500 at 18.0 IEER2; $1,000 per ton up to $10,000 at 20.0 IEER2. Funding is limited and allocated on a rolling first-come basis within the calendar year; applications not funded in 2026 are not held over.
Timing: Calendar-year 2026 funding, first come first served. Applications not awarded in 2026 are not carried into 2027.
“"Class A — Minimum SEER2 of 18.0: $500 per ton not to exceed $1,500 per dwelling … Minimum SEER2 of 20.0: $750 per ton not to exceed $2,250 … Minimum SEER2 of 22.0: $1,000 per ton not to exceed $3,000. Class B — Minimum IEER2 of 16.0: $500 per ton not to exceed $5,000 … Minimum IEER2 of 18.0: $750 per ton not to exceed $7,500 … Minimum IEER2 of 20.0: $1,000 per ton not to exceed $10,000." — 2026 High Efficiency Air Source Heat Pump Grant Program Application, Delaware Electric Cooperative, revised May 2026, p. 1.”
Our energy expert: Delaware Electric Cooperative publishes two schedules here, and which one applies turns on your member class. A Class A member — average monthly peak demand under 50 kW, where a household sits — is on $500 per ton up to $1,500 per dwelling at 18.0 SEER2 or better, $750 per ton up to $2,250 at 20.0 SEER2, and $1,000 per ton up to $3,000 at 22.0 SEER2. A Class B member, at 50 kW average monthly peak demand or more, works from IEER2 instead: $500 per ton up to $5,000 at 16.0 IEER2, $750 per ton up to $7,500 at 18.0 IEER2, and $1,000 per ton up to $10,000 at 20.0 IEER2. The Class B ceilings are not open to a household. Funding is limited and allocated first come, first served within the calendar year, and applications not awarded in 2026 are not carried into 2027; confirm availability with the co-op before you specify equipment.
Geothermal Heat Pump Grant
Estimated benefit: Newly installed systems: $1,500 per ton, not to exceed $7,500 per dwelling or facility, at an Energy Efficiency Ratio of 18.0 and a Coefficient of Performance of 3.6. Replacement systems: $500 per ton, not to exceed $1,500 per dwelling or facility, at the same efficiency. Projects must be installed by a contractor registered with DNREC's Division of Climate, Coastal and Energy. Funding is limited and allocated within the calendar year.
Timing: Calendar-year 2026 funding, first come first served; not carried into 2027.
“"a. Newly Installed Systems — $1,500 per ton for new systems, not to exceed $7,500 per dwelling/facility installed with an Energy Efficiency Ratio (EER) of 18.0 and Coefficient of Performance (COP) of 3.6. b. Replacement Systems — $500 per ton for replacement systems, not to exceed $1,500 per dwelling/facility installed with an Energy Efficiency Ratio (EER) of 18.0 and Coefficient of Performance (COP) of 3.6 or greater." — 2026 Geothermal Heat Pump Grant Program Application, Delaware Electric Cooperative, revised May 2026, p. 1.”
Our energy expert: Delaware Electric Cooperative pays three times as much for a new geothermal system as for a replacement — $1,500 a ton up to $7,500, against $500 a ton up to $1,500. That gap is deliberate: the expensive part of geothermal is the ground loop, and the co-op is paying toward putting one in, not toward swapping the box on the end of it. If you are building, or if the site has never had a loop, this is the moment. Both rates require EER 18.0 and COP 3.6 and a contractor registered with DNREC.
Solar Water Heating Grant
Estimated benefit: Up to 20% of the total installed cost. Grants will not exceed $2,000 for a Class A system (member with average monthly peak demand under 50 kW) or $3,500 for a Class B system (50 kW or more). Where the solar water heating is integrated into a radiant heating application, the grant is up to 20% of the installed cost of the solar portion, not exceeding $2,500 Class A or $3,500 Class B. Class A systems must be certified to SRCC OG-300 with a freeze tolerance limit of minus 21°F without electrical power; Class B systems must use SRCC OG-100 certified collectors and submit a design and predicted performance calculation verified by a professional engineer. Solar pool heating is not eligible.
Timing: Calendar-year 2026 funding, first come first served; not carried into 2027.
“"the Renewable Resource Program offers grants for solar water heating systems installed by qualified contractors and member-owners up to 20% of the total installed cost. Grants will not exceed $2,000 per Class A systems and $3,500 per Class B systems. Solar water heating systems integrated into a radiant heating application are eligible for a grant up to 20% of the installed cost of the solar energy portion of the system. Grants will not exceed $2,500 per Class A systems and $3,500 per Class B systems." — 2026 Solar Water Heating Grant Program Application, Delaware Electric Cooperative, revised December 2025, p. 1.”
Our energy expert: Delaware Electric Cooperative's published schedule is up to 20% of the total installed cost of solar water heating, capped at $2,000 for a Class A member — average monthly peak demand under 50 kW — and $3,500 for a Class B member at 50 kW or more. Where the system is integrated into a radiant heating application, the cap is $2,500 Class A and $3,500 Class B, on the solar portion only. Check certification before you sign anything: a Class A system must be SRCC OG-300 certified with a freeze tolerance limit of minus 21°F without electrical power, and a Class B system needs SRCC OG-100 certified collectors plus a design and predicted performance calculation verified by a professional engineer. Solar pool heating is not eligible, and 2026 funding is first come, first served and is not carried into 2027.
Electric Golf Cart Rebate
Estimated benefit: $750 per electric golf cart, up to $7,500 in total for ten carts purchased. Application, itemised receipt and photographs of the model and serial numbers must be emailed within 60 days of the purchase date. Carts must be purchased by 31 December 2026.
Timing: Must be purchased by 31 December 2026; application within 60 days of purchase.
“"Delaware Electric Cooperative is offering a $750 rebate on electric golf carts, up to a total of $7,500 total for 10 golf carts purchased." (p. 1) and "Must be purchased by December 31, 2026." (p. 2) — Electric Golf Cart Rebate Application, Delaware Electric Cooperative, revised December 2025.”
Our energy expert: An unusual one, and genuinely useful in Sussex County. Delaware Electric Cooperative pays $750 per electric golf cart, up to ten carts and $7,500 — which puts it within reach of a community, a club or a groundskeeping fleet as well as a household. Buy by 31 December 2026 and get the application in within 60 days of the purchase date, with the receipt and photographs of the model and serial plates.
Small Wind Turbine Grant
Estimated benefit: $0.85 per watt, not to exceed $2,500, for a small grid-connected wind turbine installed by a qualified contractor. Turbines must be at least 500 watts. Systems must carry a full five-year warranty against component failure, malfunction and premature output degradation. Grants are not provided for energy above the member's average annual consumption. The co-op may reject applications on the basis of the proposed turbine's location.
Timing: Calendar-year 2026 funding, first come first served; not held over.
“"the DEC Renewable Resource Program offers incentives of $0.85 per watt not to exceed $2,500 for small grid-connected wind turbines installed by a qualified contractor for a qualified member-owner. Small wind turbines shall be at least 500 watts." — 2026 Small Wind Turbine Grant Program Application, Delaware Electric Cooperative, revised December 2025, p. 1.”
Our energy expert: Eighty-five cents a watt toward a small wind turbine, to a ceiling of $2,500 — so the cap is reached at about three kilowatts and anything larger earns no more. The turbine has to be at least 500 watts, grid-connected, professionally installed and warranted for five years. Note that the co-op reserves the right to refuse an application on siting grounds, so talk to them about the location before you commission a mast.
City of Newark Electric Department, through DEMEC 5 programs
Newark Green Energy Fund — Photovoltaic Grant
Estimated benefit: $1.00 per watt for the first 5 kW and $0.50 per watt above 5 kW for residential and non-residential systems, or $1.25 per watt at all sizes for non-profits. Maximum grant $3,500 for residential, non-residential and non-profit alike. Calculated on the smaller of total inverter AC watts or PV system DC watts. A photovoltaic system may not have eligible qualifying costs above $12 per watt. Applications must be submitted BEFORE installation; applying after installation may exclude the project from funding. Funds are limited and subject to availability.
Timing: Funds are limited and subject to availability; contact DEMEC about grant payment timelines and program funding before installing.
“"Photovoltaic Systems - Calculated using the smaller of total Inverter AC Watts or PV System DC watts — Newark: Residential & Non-Residential Cost ($/Watt) 0+ to 5kW $1.00, 5kW+ $0.50; Non-Profit Cost ($/Watt) All KW $1.25; Maximum Grant Residential $3,500, Non-Residential $3,500, Non-Profit $3,500." — Municipal Green Energy Program Regulations, Delaware Municipal Electric Corporation, Exhibit A, 'Newark Green Energy Fund Incentives/Grants', revision dated 20 June 2023, p. 18.”
Our energy expert: City of Newark electric customers have a solar grant of their own, and the state's Green Energy Program is Delmarva-only, so the two do not overlap. Newark's fund pays a dollar a watt on the first five kilowatts and fifty cents a watt above that, with a maximum grant of $3,500. Apply BEFORE installation — applying afterwards may exclude the project — and note that funds are limited. Milford also publishes the Municipal Green Energy Fund; which DEMEC members currently contribute to it is a question for DEMEC.
Newark Green Energy Fund — Geothermal Heat Pump Grant
Estimated benefit: $800 per ton for the first two tons and $700 per ton above two tons, for residential systems, to a maximum grant of $4,400. Systems must meet an Energy Efficiency Ratio of 18 or better and a Coefficient of Performance of 3.6 or better. Non-residential and non-profit applicants are directed to the Delaware Sustainable Energy Utility. Applications must be submitted BEFORE installation; applying after installation may exclude the project from funding. Funds are limited and subject to availability.
Timing: Funds are limited and subject to availability; contact DEMEC about grant payment timelines and program funding before installing.
“"Geothermal Heat Pumps System - Energy Efficiency Ratio (EER) ≥ 18 and Coefficient of Performance (COP) of ≥ 3.6 — Newark: Residential First 2 Tons ($/Ton) $800, Over 2 Tons ($/Ton) $700; Maximum Grant Residential $4,400. Non-Residential & Non-Profit: SEU." — Municipal Green Energy Program Regulations, Delaware Municipal Electric Corporation, Exhibit A, 'Newark Green Energy Fund Incentives/Grants', revision dated 20 June 2023, p. 18.”
Our energy expert: Newark pays $800 a ton for the first two tons of a geothermal system and $700 a ton after that, up to $4,400 — the largest grant in the city's fund. The efficiency floor is firm: EER of 18 and COP of 3.6. Businesses and non-profits are pointed at the Delaware Sustainable Energy Utility instead, so check which door you are at before you commission a loop design.
Newark Green Energy Fund — Solar Water Heating Grant
Estimated benefit: $1.00 per OG-300 kWh saved for residential systems, to a maximum grant of $3,000 for a water-heater-only system, or $5,000 where the solar water heating is integrated into a radiant heating application. Non-residential and non-profit applicants are directed to the Delaware Sustainable Energy Utility. Applications must be submitted BEFORE installation; applying after installation may exclude the project from funding. Funds are limited and subject to availability.
Timing: Funds are limited and subject to availability; contact DEMEC about grant payment timelines and program funding before installing.
“"Solar Water Heater Only — Newark: Residential ($/OG300 - kWhr Saved) $1.00; Maximum Grant Residential $3,000. Solar Water Heating Integrated into a Radiant Heating Application — Newark: Residential $1.00; Maximum Grant Residential $5,000." — Municipal Green Energy Program Regulations, Delaware Municipal Electric Corporation, Exhibit A, 'Newark Green Energy Fund Incentives/Grants', revision dated 20 June 2023, p. 18.”
Our energy expert: A dollar for every kilowatt-hour a year the system is certified to save, up to $3,000 — or up to $5,000 if the solar heat also feeds a radiant heating system. Because the grant is paid on the OG-300 rating rather than on cost, the certification number on the equipment is what determines your cheque; ask for it before you choose a system.
Newark Green Energy Fund — Small Wind Turbine Grant
Estimated benefit: 33.33% of total installed costs, to a maximum grant of $7,500 residential, $15,000 non-residential or $10,000 non-profit. Qualifying wind turbine systems must be at least 500 watts and must not exceed $5.00 per watt installed. Applications must be submitted BEFORE installation; applying after installation may exclude the project from funding. Funds are limited and subject to availability.
Timing: Funds are limited and subject to availability; contact DEMEC about grant payment timelines and program funding before installing.
“"Small Wind Turbines — Not to Exceed % below of total installed costs: Newark Residential 33.33%, Non-Residential 33.33%, Non-Profit 33.33%; Maximum Grant Residential $7,500, Non-Residential $15,000, Non-Profit $10,000." — Municipal Green Energy Program Regulations, Delaware Municipal Electric Corporation, Exhibit A, 'Newark Green Energy Fund Incentives/Grants', revision dated 20 June 2023, p. 18.”
Our energy expert: A third of the installed cost of a small wind turbine, capped at $7,500 for a household and $15,000 for a business. Two limits shape it: the turbine must be at least 500 watts, and the installed cost cannot exceed $5.00 a watt, which rules out over-engineered small installations. Newark's caps are well above the state co-op's $2,500 ceiling for the same measure.
Newark Green Energy Fund — Fuel Cell Grant
Estimated benefit: 33.33% of total installed costs, to a maximum grant of $7,500 residential, $15,000 non-residential or $10,000 non-profit. Applications must be submitted BEFORE installation; applying after installation may exclude the project from funding. Funds are limited and subject to availability.
Timing: Funds are limited and subject to availability; contact DEMEC about grant payment timelines and program funding before installing.
“"Fuel Cells — Not to Exceed % below of total installed costs: Newark Residential 33.33%, Non-Residential 33.33%, Non-Profit 33.33%; Maximum Grant Residential $7,500, Non-Residential $15,000, Non-Profit $10,000." — Municipal Green Energy Program Regulations, Delaware Municipal Electric Corporation, Exhibit A, 'Newark Green Energy Fund Incentives/Grants', revision dated 20 June 2023, p. 18.”
Our energy expert: A third of installed cost toward a fuel cell, capped at $7,500 for a household, $15,000 for a business and $10,000 for a non-profit. Rare enough that most installers in the region will not have quoted one, but it is on the published schedule and it is real money.
DNREC Division of Climate, Coastal and Energy 1 program
Delaware Clean Vehicle Rebate Program
Estimated benefit: New battery electric vehicle with a base MSRP below $40,000: $2,500. New battery electric vehicle with a base MSRP between $40,000 and $50,000: $1,500. New plug-in hybrid with a base MSRP below $50,000: $1,000. Used battery electric vehicle with a fair market purchase price of $40,000 or less: $2,500. Used plug-in hybrid with a fair market purchase price of $40,000 or less: $1,000. New-vehicle amounts are set on base MSRP, used-vehicle amounts on the Kelley Blue Book Fair Purchase Price, both at the time of program approval. This is a cash rebate, not a tax credit. A lease must run at least 36 months.
Timing: The rebate must be applied for within 90 days of the purchase date. Applications for vehicles purchased before 1 May 2026 are no longer accepted.
“"Rebate Amounts as of May 1, 2026 — New Battery Electric Vehicles with a base MSRP below $40,000: $2,500. New Battery Electric Vehicles with a base MSRP between $40,000 and $50,000: $1,500. New Plug-in Hybrid Vehicles with a base MSRP below $50,000: $1,000. Used Battery Electric Vehicle with a fair market purchase price of $40,000 or less: $2,500. Used Plug-in Hybrid Vehicles with a fair market purchase price $40,000 or less: $1,000." — DNREC, The Delaware Clean Vehicle Rebate Program, retrieved 2026-09-24.”
Our energy expert: DNREC publishes a cash rebate schedule for clean vehicles, and it covers used vehicles as well as new. New battery electric under $40,000 base MSRP: $2,500. New battery electric between $40,000 and $50,000: $1,500. New plug-in hybrid under $50,000: $1,000. Used battery electric with a fair market purchase price of $40,000 or less: $2,500, and a used plug-in hybrid on the same price test: $1,000. New-vehicle amounts are set on base MSRP and used-vehicle amounts on the Kelley Blue Book Fair Purchase Price, both at the time of program approval. Three procedural points govern the claim: this is a rebate, not a tax credit; the application must be in within 90 days of the purchase date; and a lease must run at least 36 months. Vehicles purchased before 1 May 2026 are no longer accepted.
Energize Delaware (Delaware Sustainable Energy Utility) 1 program
Delaware SREC Procurement Program
Estimated benefit: Multi-year contracts to sell SRECs, awarded by competitive bid. Bids are ranked lowest price first within tiers set by system size, interconnection date and ownership type, and accepted until the tier is full. Systems built with Delaware labor or Delaware-manufactured parts earn a 10% SREC production bonus per qualification, 20% if both apply; the Delaware Public Service Commission certifies eligibility. The clearing price is not a published figure — it is what the accepted bids settle at.
Timing: At least one solicitation per year; bid window is two weeks.
“"Solar properties built with Delaware labor or Delaware-manufactured parts may receive a 10% SREC bonus for each qualification. Properties meeting both criteria qualify for a 20% bonus. The Delaware Public Service Commission certifies whether a property meets the bonus requirements." — Energize Delaware, Residential → Grants & Rebates, retrieved 2026-09-24.”
Our energy expert: If you own a solar array in Delaware, the electricity is only half of what it earns. Every megawatt-hour also creates a Solar Renewable Energy Credit, and Delmarva Power has to buy a quota of them each year. Energize Delaware runs the auction. You bid the price you are willing to accept, the lowest bids in each tier win, and the winners get a multi-year contract. Build with Delaware labor or Delaware-made parts and your output is credited at a 10% bonus for each — 20% if both. What you will actually be paid depends on where the bidding lands, so treat it as income to be won rather than a fixed rate.
