Plus Power and the Tennessee Valley Authority (TVA) announced on Tuesday a 20-year energy storage agreement to add 200 megawatt / 800 megawatt-hour utility-scale battery energy storage in Jackson County.
TVA, the largest public energy provider in the United States, selected the project through a request for proposal issued in early 2025 to supply new capacity resources needed across the region. The standalone system, developed by Plus Power's Crawfish Creek Energy Storage project in Jackson County, was chosen to help TVA meet its system needs and strengthen U.S. energy security.
Under the agreement, TVA will charge and dispatch energy from the battery system based on system needs, while Crawfish Creek Energy Storage retains ownership of the facility.
"Battery storage is essential to protecting the reliable, affordable electricity our region depends on to power next generation technologies," said Monika Beckner, TVA Vice President of power supply and fuels. "Projects like Crawfish Creek strengthen the Valley's energy security, improve our ability to manage extreme conditions, and help unleash American energy—reinforcing reliability, affordability, and America's energy dominance."
Construction on Crawfish Creek Energy Storage is expected to begin in 2028, with commercial operation anticipated in summer 2029. The project is expected to create 50 to 100 construction jobs in Jackson County and support four full-time operations roles once complete.
The system provides TVA with flexible capacity by storing lower-cost energy during off-peak periods and delivering it during peak demand. It will also provide grid-forming capabilities—fast frequency response, regulation, and operating reserves—to support growth in advanced manufacturing, data centers, and industrial investment across the Valley.
Crawfish Creek supports TVA's broader effort to develop 6,200 megawatts of new generation to meet increasing electricity needs across north Alabama and the Tennessee Valley.
"Plus Power is proud to support energy resilience in Jackson County and the Tennessee Valley, a key region for America's military, aerospace, and nuclear innovation," said Brian Duncan, chief commercial officer at Plus Power. "Battery energy storage systems are flexible and millisecond fast, making Crawfish Creek uniquely suited to meet the region's evolving needs. We are excited to partner with TVA to deliver a resource that supports economic expansion while strengthening American energy dominance and security."
With Crawfish Creek Energy Storage, Plus Power is entering its seventh state market and expanding into the Southeast. The company owns and operates nine facilities that provide enhanced power reliability to Arizona, Hawaii, Maine, Massachusetts, and Texas, totaling 1,650 megawatts / 4,150 megawatt hours.
