Form’s 100-hour iron-air battery system to expand access

Read Time: 2 mins

Form Energy, Inc., an American technology company developing and commercializing a new class of cost-effective, multi-day energy storage systems, announced today 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.

Bob Frenzel, Chairman, President and CEO of Xcel Energy, said: “We’re on track to reduce our electric system carbon emissions 80 percent by 2030 and to deliver carbon-free electricity by 2050. As we build more renewable energy into our systems, our partnership with Form Energy opens the door to significantly improve how we deliver carbon-free energy so that we can continue to provide reliable and affordable electric service to our customers well into the future.”

Form Energy and Xcel Energy collaborated on extensive modeling with Formware™, Form Energy’s next-generation investment and operational modeling tool for power grids. This modeling helped Xcel Energy validate how Form’s multi-day storage will enhance Xcel Energy’s ability to reliably and cost-effectively integrate large amounts of wind energy and other renewable resources on its system. Additionally, this analysis demonstrated that Form Energy’s 100-hour iron-air battery technology will strengthen the grid against normal day-to-day, week-to-week, and season-to-season weather variability, in addition to extreme weather events including severe winter storms and polar vortex events.

Mateo Jaramillo, CEO and Co-founder of Form Energy, added, “Xcel Energy operates across some of the richest wind-resource areas in North America. We’re very pleased to work with the Xcel Energy team to maximize use of its renewable generation by providing a technology solution that will ensure their customers benefit from reliable and cost-effective service year-round. This partnership highlights Xcel Energy’s commitment to ensuring grid resiliency and reliability, energy security, and access to low-cost clean energy when and where it is needed – every day of the year.”
