Headline Story: Form’s $1B Google Deal
Iron-air leader Form Energy has signed a major $1 billion deal to support a cleantech-powered Google data center in Pine Island, Minnesota.
- Through the arrangement, electric utility Xcel Energy will install a 300 megawatt / 30 GWh Form battery array to dispatch energy for up to 100 hours straight, 24/7/365.
- The selection followed a rigorous process in which Form demonstrated its capabilities with internal installations that Xcel could examine.
- The data center will run core Google services including Workspace, Search, YouTube and Maps.

👉 Octet’s Take: “This deployment suggests that LDES is moving from pilot stage to system-critical infrastructure — especially where load growth is concentrated and reliability expectations are non-negotiable” writes Octet’s Emily Dickens on LinkedIn. “Instead of asking, ‘How do we fuel this demand spike?’, we should be asking, ‘How do we scale long-duration storage fast enough to meet it?’”
