CalSEED — California Sustainable Energy Entrepreneur Development Initiative
California Energy Commission (administered by New Energy Nexus)
$150K Concept, up to ~$650K total
CA clean-energy seed grant
CalSEED is California's flagship early-stage clean energy grant program, funded by the California Energy Commission's Electric Program Investment Charge (EPIC) and administered by the nonprofit New Energy Nexus. It provides non-dilutive grant funding plus structured mentoring, technical consulting, and business-development support to help California clean energy innovators move from concept to prototype. The program awards a Concept Award of $150,000 to roughly 20–25 projects each annual cycle; Concept awardees who win the subsequent Business Plan Competition can advance to a Prototype Award of an additional $450,000. CalSEED has deployed roughly $23M to ~137 awardees since 2017 as part of a $48M program, with Cohort 7 prototype awards announced in April 2026 and the next Concept Award cycle deadline targeted for March 31, 2026.
