[1/5] Arlo Brownlee, an engineer, checks battery banks at GlidePath's Byrd Ranch energy storage facility in Sweeny, Texas, U.S., May 23, 2023. The battery rush also puts the Republican-controlled state at the forefront of President Joe Biden's push to expand renewable energy use. Reuters drew on previously unreported data and interviewed more than a dozen executives from private equity firms, utility companies and energy storage providers involved in some of the biggest battery storage deals for this report. But the legislation also contains provisions that industry groups said could encourage investment in battery storage. Miller said he expects ancillary market prices to "collapse" as more battery storage comes online.
