Firma Power wants clean energy to be the default for data centers

San Francisco and Princeton-based startup Firma Power has raised about $1.4 million in seed funding and built FirmaOS, software that assembles portfolios of wind, solar and battery projects for a specific data center in minutes. The company says the approach can power data centers faster and cheaper than building new gas plants, and it is already working on roughly a dozen projects with hyperscalers and AI cloud firms.

• The U.S. is set to add a record 86 GW of wind, solar and storage in 2026
• A single AI data center can now need 500 MW to 1 GW of power
• FirmaOS builds a clean energy portfolio in minutes instead of months
• The startup raised around $1.4 million in a February 2026 seed round
