The Transforming Neighborhoods Initiative (TNI) focuses on uplifting neighborhoods in Prince George's County that face significant economic, health, public safety, and educational challenges. Via the initiative, the County is working to improve the quality of life in those neighborhoods, while identifying ways to improve service delivery throughoutEnergy new map the county for all residents. 

The TNI Clean Energy Grant builds on the Transforming Neighborhoods Initiative, and seeks to help alleviate efficiency challenges faced by County residents. Taking the link between energy efficiency and social inequality to heart, and helping to break the cycle of energy inefficiency and energy poverty, the TNI energy grants are to assist TNI residents with adopting energy efficiency and water efficiency measures, and for subsequent access to rooftop solar photovoltaics upon the successful implementation of efficiency measures. 


Funds can be used to offset the costs of various energy efficiency, water efficiency, and retrofitting measures, and for professional services needed to address the barriers to efficiency and/or solar energy for the respective property. 

Participants in the TNI Clean Energy Grant Program, are required to apply to the applicable EmPOWER Maryland incentive program: for market rate applicants, Pepco's Home performance with ENERGY STAR Program, or for income-qualified applicants, the Maryland Department of Housing and Community Development's (DHCD) Low Income Energy Efficiency Program (LIEEP).

Grants will be available to offset the costs of measures as recommended by a home energy assessment, to facilitate implementation of efficiency measures - funds may also be used to address challenges that would prevent the adoption of recommended efficiency measures. Upon completion of energy efficiency upgrades, residents in TNI designated communities may apply for rooftop solar grants. 


Grants up to $5,000, after incentives from the respective EmPOWER Maryland programs, to offset: 

a)  Grants to offset up to $100 of the cost, post EmPOWER Maryland incentive, of the home energy audit. 

b) The participant's cost to address deficiencies which prevent adoption of recommended efficiency measures (i.e. health and safety measures).

c) The participant's cost to effect efficiency measures.


Applicants to the program must: 

Subject to the availability of funds, grants will be dispersed on a first-come, first-served basis.

See TNI Clean Energy Program solar grant application for more details on eligibility.

Please visit OCS Sustainable Energy Program Implementation Plan including grant applicability information to learn more as well.


This option is available to residents in the TNI designated communities and in the Pepco service area. Grantees must successfully implement efficiency measures in order to qualify for funding for solar PV. The minimum system size to qualify for a grant is 2kW and have three different program routes:

i.  For income-qualified applicants (total household gross incomes that are less than 60% of the median income for Prince George's County as specified by Maryland Department Housing and Community Development), the maximum grant for homeowner owned systems is 100% of cost up to $10,000.

ii. Grants for leased systems or power purchase agreements are up to $2,000.

iii. For market rate applicants, the maximum grant for homeowner owned systems is $5,000.

Eligible costs are front costs for the solar energy system including any parts, component, or accessory equipment necessary to operate the device, and reasonable costs associated with installing the device. A maximum of 15% of the grant can be spent on reasonable measures to facilitate the installation of the system on a rooftop. SEP staff should be contacted to ensure the measure qualifies. 

Subject to the availability of funds, grants will be dispersed on a first-come, first-served basis.


Residents canchoose their own solar contractor to install their rooftop solar system. Inorder for a solar company to become a participating contractor as a part of theTNI Clean Energy Rooftop Solar Grant, they must be registered as a vendor ofPrince George’s County with the Contract Administration and Procurementdivision. 

➢ To begin, companies are to complete thevendor registration form which can be found by visiting

If you havefurther questions about vendor registration, please contact the Supplier Registration Coordinatorin the Contract Administration and Procurement division at 301-883-6400.
