The Clean Energy Program, Energy Efficiency grant award provides up to $6,250 in funds for residential energy efficiency measures, in addition to Washington Gas incentives. The maximum grant award amount is $6,250 (for gas incentives), of which $2,500 can be allocated towards natural gas incentives, and up to 60% of total grant award amount ($3,750) can be allocated towards air sealing and insulation (does not include ancillary equipment like baffles/ventilation). 

Note: Please be advised the Clean Energy Program, Energy Efficiency Grant award is no longer funding electric incentives due to funding availability. All electric homes will not qualify for the grant award.

    To be eligible for this grant award, you will need to show proof of being a Pepco and Washington Gas customer, as evidenced by a recent copy (within the last 3 months) of your utility bill to apply for gas incentives. Paper copies of the bills are typically mailed to the customer's address on record. For Pepco customers with internet access, account information is available via Pepco’s account portal here, and Washington Gas customers can access their accounts via the Washington Gas’ account portal here


  3. Live in a single-family, townhouse residence, or condominium* (please see Section II for more details) that is individually metered  (built before March 23, 2016), in one of the following designated Energy Resiliency Communities (ERC): Bladensburg - East Riverdale; Forestville;  Hillcrest Heights - Marlow Heights; Kentland - Palmer Park; Oxon Hill – Glassmanor; Silver Hill; Suitland - Coral Hills; Langley Park; and Woodlawn – West Lanham. 


    To confirm you are in one of the ERC communities, look up your address by using the ERC Address Locator here. Please note the ERC Address Locator is the definitive tool for determining the eligibility of an application. 


  4. The energy audit report must demonstrate, without direct install measures, that the project will achieve 10% energy savings or greater (therms and energy cost) for applications requesting gas incentives. Cost-effectiveness is taken into consideration as well.

If you are subcontracting, you will be required to provide proof of your license to perform natural gas work in the County, as well as an updated and signed contract between the contractor and subcontractor.
