Please refer to the program guidelines for more details for the specific pathway requirements and full list of eligible measures. What is the Energy Efficiency Investment Fund?
The Energy Efficiency Investment Fund (EEIF) is a rebate program that provides financial assistance to Delaware non-residential entities (e.g. commercial, industrial, non-profits, etc.) seeking to replace aging, inefficient equipment with energy efficient alternatives.
The primary purpose of EEIF is to improve the energy efficiency of businesses by reducing energy consumption, maximizing energy savings, and improving environmental performance. Additionally, EEIF encourages businesses to decrease energy use in order to not only curb greenhouse gas emissions, but also ensure that the program remains aligned with the sustainability and energy conservation goals outlined in Delaware’s Climate Action Plan.
Who can participate in the EEIF program? The EEIF Program is available to all non-residential, commercial, and industrial entities throughout the State of Delaware who pay the public utility tax (PUT) on their monthly electric/natural gas utility bills. Applicants that do not pay the PUT may be able to receive funds through the Regional Greenhouse Gas Initiative (RGGI) as they become available, though not a guarantee.
What types of projects can receive funding through EEIF? The EEIF Program offers four primary rebate pathways to Delaware non-residential entities with both existing building and new construction projects. Prescriptive pathway rebates are for common energy-efficient improvements, such as lighting and lighting control measures, HVAC and water heating equipment, and appliances and food service equipment.
Custom pathway rebates are designed for more complex, non-standard measures that go beyond the equipment funded by Prescriptive rebates. These include, but are not limited to: steam system, building envelope, and chiller and boiler improvements.
Energy Assessment pathway rebates are designed to support both single-purpose and comprehensive energy audits that aid facilities in need of technical evaluations for appropriate, cost-effective energy efficiency improvements, specific to each building’s needs. Combined Heat and Power (CHP) pathway rebates are ideal for large facilities with high annual hours of operation and high thermal loads.
The CHP rebate pathway provides incentives for five CHP systems, including microturbines, reciprocating engines, gas turbines, steam turbines, and fuel cells. For more information on specific pathway requirements and eligible measures, please refer to the EEIF Program Guidelines and Operational Procedures . Is there a cap on the amount of funding EEIF can provide for a single project?
Yes. With the exception of energy assessments, the EEIF 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.
For energy assessment rebates, EEIF may award the applicant up to the lesser of (1) 50% of the cost of the energy audit or (2) the maximum award cap of $5,000 for a single-purpose audit or $10,000 for a comprehensive energy audit. How do I apply for an EEIF grant?
Prior to applying, it is recommended to first review the Program Guidelines and Operational Procedures for your specific rebate pathway’s eligibility and documentation requirements. If you have any questions about the application process or need help completing the application, please email DCCE. EnergyRebates@NV5.
com or call 802-484-5645. To start a new application, visit the Energy Efficiency Application Portal and register as either an applicant or contractor/installer. Once registered, choose the rebate pathway that best suits your proposed project and begin to answer all required application questions and submit all required documents for pre-approval prior to construction.
It is important to note that Prescriptive and Energy Assessment project applicants may choose to forego pre-approval and apply for rebate funds within 30 days of the invoice date. Is there a deadline for submitting applications? Applications are accepted on a year-round, rolling basis.
All rebate awards are subject to funding availability. How are rebates selected? All rebates are provided on a first-come, first-serve basis for qualified applicants and projects.
Estimated rebate awards can be determined using the energy calculators found in each rebate pathway in the online Energy Efficiency Application Portal . Does my project have to be pre-approved? With the exception of Prescriptive and Energy Assessment projects, all other projects must be pre-approved before equipment is purchased or any work has started.
Since there is a limited amount of rebate funds available, funding for your project will be reserved once your application has been pre-approved. Applicants who do not secure pre-approval for their Prescriptive or Energy Assessment projects assume full risk of project ineligibility or lack of funds. What documentation is required for pre-approval?
Each EEIF rebate pathway has specific required documents listed in the application portal. In general, all projects require: Specification (cut) sheets and model numbers for all equipment Itemized quotes and estimates for all equipment Electric and/or natural gas utility bills Completed EEIF online application and energy savings calculator What documentation is required for final approval?

On June 11, 2026, U.S. District Judge Richard Gergel ruled that the EPA's February 2025 termination of the $2.8 billion Environmental and Climate Justice Block Grant Program — created by Section 60201 of the Inflation Reduction Act — was arbitrary, capricious, and unlawful. The ruling voids the termination but does not order the EPA to resume the program, leaving the September 30, 2026 statutory deadline as the binding constraint. For the 116 grantees and the coalition of nonprofits, cities, and tribal partners that were already in award negotiations, the next 105 days will determine whether the program survives in any operational form or migrates entirely to the Court of Federal Claims as a damages action.
