State of Delaware Energy Efficiency Programs & Incentives

Energy Efficiency Investment Fund 

The Energy Efficiency Investment Fund (EEIF) was created to help Delaware businesses make strategic investments in capital equipment and facility upgrades that will help decrease operating costs, reduce energy consumption, and improve environmental performance. The program offers funding for technical assistance, as well as competitively awarded grants and loans for implementation of energy efficiency projects. 

Weatherization Assistance Program 

The U.S. Department of Energy (DOE) Weatherization Assistance Program reduces energy costs for low-income households by increasing the energy efficiency of their homes. 

Delaware Clean Transportation Incentive Program 

The Delaware Clean Transportation Incentive Program provide incentives for Delawareans to purchase new, leased or retrofitted alternatively-fueled vehicles, electric vehicle charging equipment for electric vehicles and install alternative fueling infrastructure. CTIP programs are currently funded at $2.7 million, with funding through Delaware’s participation in the Regional Greenhouse Gas Initiative (RGGI). 

Delaware Energy Efficiency Advisory Council

The Delaware Energy Efficiency Advisory Council (EEAC) consists of 13 representatives from a wide range of stakeholders including DEMEC who assist with the development and deployment of energy efficiency programs and financing mechanisms.

Sustainable Energy Utility (SEU) Incentives

Home Performance with ENERGY STAR  

Home Performance with ENERGY STAR takes a whole-house approach to maximize residential energy savings. A comprehensive home energy audit is performed first to identify energy saving improvements that are right for your existing home. Then, customers can take advantage of potential rebates for completing those improvements.  

Low-Interest Commercial Loan Program  

The Low-Interest Commercial Loan Program encourages the adoption and installation of energy efficiency measures and customer-sited renewable generation systems by providing financing to credit worthy businesses and non-profits located in existing facilities in Delaware.  

Commercial and Industrial Energy Assessments  

Commercial and Industrial Energy Assessments are available to all existing non-residential buildings. Properties that are eligible for an energy assessment incentive include businesses, non-profit organizations, and the public sector. For non-profit/Governments: the SEU covers 90% of audit cost; this can range from $400 to $1600 depending on energy usage. For profit companies will have their fee determined after a consultation with the SEU.

Federal Energy Tax Credits


The Federal tax credit is applicable to certain ENERGY STAR and renewable energy products.  Not all ENERGY STAR or renewable energy systems qualify for a tax credit.
