Xcel Energy, Form Energy team to deploy iron-air battery systems

Form Energy announced that it has entered into definitive agreements with Xcel Energy to deploy its iron-air battery systems at two of Xcel Energy’s retiring coal plant sites. The storage technology will allow Xcel Energy to integrate more low-cost, renewable energy into its system and maintain reliability as it retires the coal plants in the coming years and transitions to a highly renewable future. Xcel Energy-Minnesota will deploy a 10 MW / 1,000 MWh multi-day storage system at the Sherburne County Generating Station in Becker, Minnesota. Xcel Energy-Colorado will deploy a 10 MW / 1,000 MWh multi-day storage system at the Comanche Generating Station in Pueblo, Colorado. Both projects are expected to come online as early as 2025 and are subject to regulatory approvals in their respective states.
