Cision PR Newswire | TVA and Plus Power’s Crawfish Creek Energy Storage Sign on 200 MW Battery Project to Strengthen Power Affordability and American Energy Dominance
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 to the Tennessee Valley. 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, Alabama, was chosen to help TVA meet its system needs and strengthen U.S. energy security.

Arizona Republic | SRP deploys state’s largest battery system to handle peak energy demand spikes
Salt River Project is deploying two new industrial-scale battery storage systems, including the state’s largest so far, to absorb excess energy when it’s not needed for release at later periods when demand spikes. The 250 MW Sierra Estrella facility, on nine acres in Avondale, became the largest standalone battery system in Arizona when it went online earlier this month, SRP said. It will store enough energy to power more than 56,000 residences for four hours. The 90 MG Superstition Energy facility in Gilbert will store enough power for 20,000 homes for four hours.

USA Today | “This state is quickly becoming America’s clean energy paradise. Here’s how it’s happening.”
Hawaii pledged to be “Coal free by ’23,” and state law mandates 100% clean energy in just 21 years. Attaining that goal came closer last month when Plus Power’s Kapolei Energy Storage, an enormous 185-megawatt battery near Honolulu, hummed into full operation.

The Texas Tribune | “As brutal heat tests Texas’ power grid, batteries play a small but growing role in keeping the lights on”
Battery supporters credit the technology for helping during tight times when every megawatt counts to keep the power on for Texas’ growing population. This summer, batteries have mostly sold their power to meet high demand around 7 p.m. or 8 p.m. when solar production winds down as the sun sets but temperatures are still high. Energy consultant and battery advocate Doug Lewin calls that the “white knuckle part of the evening” for ERCOT, when batteries’ relatively small contribution to the grid can still be “determinative” to meeting what has been record-high demand during Texas’ second-hottest summer ever.
