$147 Million Grant for Maine Energy Storage Project

The former paper mill site in Lincoln, Maine, is set to become the location for the world's largest multi-day energy storage facility, supported by a $147 million federal grant from the U.S. Department of Energy. Governor Janet Mills and Maine's congressional delegation announced that the project, developed by Form Energy, will utilize innovative iron-air battery technology capable of discharging energy for up to 100 hours. This facility aims to enhance grid resilience, optimize renewable energy delivery, and help Maine achieve its goal of 400 MW of energy storage by 2030. The initiative is part of a larger $389 million regional effort under the Bipartisan Infrastructure Law, aimed at strengthening the electric grid across New England. Officials believe the project will alleviate pressure on the transmission system and reduce reliance on gas-fired power plants, providing significant benefits during extreme weather events. The Lincoln facility represents a major advancement in clean energy technology and storage capacity in the region.
