This $70,000,000 Cooperative Agreement was awarded by the U.S. Department of Energy's (DOE) Clean Energy Demonstrations program (CFDA 81.255) to Xcel Energy Services Inc. The funding will support two projects to demonstrate the viability and competitiveness of iron-air battery technology for multi-day energy storage: At a power station site in central Minnesota, construct and operate a 10 MW, 100-hour iron-air battery storage system. At a power station site in southern Colorado, construct and operate a separate 10 MW, 100-hour iron-air battery storage system. The objectives of this project are to: 1) prove the capability of iron-air batteries for long-duration energy storage, 2) quantify the technology's performance, capital costs, and operating revenues/expenses, 3) engage with local communities to identify and deliver benefits, and 4) advance opportunities for historically underrepresented workers and businesses. The award duration is from June 1, 2024 to January 31, 2029.
