The largest US battery storage project is the Darden Clean Energy Project in California, approved in 2025, with a capacity of up to 4.6 GW (4,600 MW). Which is better, PSP or BESS? Pumped Storage Projects (PSP) are currently more cost-effective and preferred for longer-duration grid storage due to lower levelized cost and longer lifespan.
Battery energy storage is rapidly transforming the U.S. power landscape. In 2025, utility-scale battery storage is projected to expand by a record 18.2 GW, following a historic 10.3 GW added in 2024. These systems play a crucial role in balancing supply and demand, enhancing grid stability, and supporting the integration of renewable energy.
Today, technology advances and dramatic cost decreases combine to set up battery energy storage as the savior for both renewables and the overarching electric grid as power demand soars and Congress rapidly phases out tax credits for wind and solar energy.
It was billed as Europe's largest battery storage project when it became operational at the end of 2014 and was revolutionary thanks to its technology providing a range of benefits to the wider electricity system, including absorbing energy then releasing it to meet demand. 6.
