Grants and concessional finance for renewable energy

227 matching capital sources on the AESFIP database · Last checked October 2026

Renewable energy projects rarely fail for lack of commercial lenders. They fail earlier — at feasibility, permitting, grid studies and first-loss capital — where only grant and concessional money works. Getting the concessional layer right is what makes the commercial layer available at all.

These funders provide grants, concessional debt, project preparation funding and catalytic first-loss capital to solar, wind, hydro, mini-grid, off-grid and energy efficiency projects. Most expect the concessional tranche to unlock a larger commercial tranche, so come with the full capital stack, not just the ask.
