AI generated summary

The American Clean Power Association reported that the U.S. achieved a record addition of 1,602 MW of battery storage capacity in the first quarter of 2025, which is comparable to the energy generation capacity of a large coal-fired power plant. By the end of March 2025, the total battery storage capacity in the country surpassed 30 GW, marking a significant 65% increase from the previous year.

Indiana notably quadrupled its energy storage capacity within just one quarter, moving from 18th to a stronger position in the national rankings for installed battery storage capacity since 2018. Johanna Neumann, Senior Director at Environment America Research & Policy Center, emphasized that battery energy storage plays a crucial role in enhancing the use of renewable energy and maintaining power supply during extreme weather and grid stress situations.
