Battery storage is proving its value when the grid needs it most.
According to new data from SEIA, battery energy storage supplied more electricity to the U.S. grid during the first eight months of 2026 than it did during all of 2025. During periods of extreme heat across states like Texas and California, batteries helped deliver power when demand was highest, supporting reliability and helping protect customers from price spikes.
As electricity demand continues to rise and heat waves put additional stress on the grid, energy storage is becoming an increasingly important part of the solution. Batteries can store energy when it is abundant and deliver it back to the grid during critical peak-demand periods, helping keep the lights on when communities need power most.
We've seen that value firsthand at Wallum Solar. During grid events in the past, the site's battery energy storage system has responded when called upon, delivering electricity to the grid during periods of high demand and helping support local reliability.
As extreme weather events become more common, projects that combine solar and storage are showing how clean energy can do more than generate electricity. They can help strengthen the grid when it matters most.
