Arizona is proving to be a national leader in utility-scale energy storage capacity, with the second-highest amount installed so far this year and one of the highest amounts in total.
A report released earlier this month from the Solar Energy Industries Association, or SEIA, along with Benchmark Mineral Intelligence found that 940 megawatt-hours of energy storage was installed in the Grand Canyon State during the first quarter, an amount surpassed only by the 2,696 megawatt-hours added in Texas and slightly ahead of the 936 megawatt-hours added in California.
That Q1 addition brings Arizona to a milestone total of more than 20 gigawatt-hours of utility-scale energy storage installed — 20.2 to be exact.
That is the third-highest amount in the U.S., behind California (60.6) and Texas (29.2). Arizona also ranked third after 2025, when it led the nation for its rate of growth in energy storage.
