Tribal Solar Gap Funding Grant Program

GRID Alternatives

Deadline Passed. Most Recent Deadline July 14, 2023. The Tribal Solar Gap Funding Grant supports solar projects of any type that require a tribal cost-share (ex. Federal or State grant programs) or are leveraging funding from other grant opportunities or initiatives. Applicants may apply for gap funding up to $250,000. These projects should be positioned to deploy solar energy with an existing funding gap (cost share) which is preventing the project from being completed. With this round of gap funding TSAF aims to enhance and strengthen tribal solar energy development and infrastructure inclusive of other impactful renewable energy technologies (battery storage, clean mobility/charging stations etc.) and to provide funding toward larger scale solar projects that benefit a significant number of tribal community members.

Funding Amount
Up to $250,000
Matching Funds
•Federal and state-recognized tribal governments in the lower 48 states and Alaska (tribal government programs, such as tribal housing authority, cultural departments, economic development entities, etc.)
