NextVolt has offloaded a 1 GWh battery energy storage system (BESS) to Exus Renewables which will take on ownership long-term. Menawhile, the developers of a 1.2 GWh BESS in Arizona have partnered with Fluence for its GridStack Pro system.
Longer-duration storage, safety-driven procurement and FEOC compliance are starting to push alternative chemistries closer to scale.
The industry faces rising demand, tighter economics and higher expectations for performance and reliability.
GridStor, Sunrun, and NRG Energy are hoping their efforts in the Texas battery energy storage (BESS) market will provide flexibility for the strained Texas ERCOT grid by catering to energy demand.
Over 5.3 GW of energy storage was deployed in Q3 2025, said a report from Wood Mackenzie and the American Clean Power Association.
CPS Energy, which acts as sole provider of electricity in San Antonio, Texas, plans to have 1,000 MW of operational or contracted storage capacity following the completion of its latest request for proposal for an additional 500 MW of additional storage capacity.
Under the real-time co-optimization structure, batteries will be recognized as both generators and loads.
Battery pack prices for stationary storage fell to $70/kWh in 2025, a 45% drop from 2024, making it the cheapest lithium-ion category for the first time, according to BloombergNEF (BNEF).
While the long-term impacts of the elimination of the United States’ federal electric vehicle tax credit remain unknown, it’s clear that battery manufacturers in the country are starting to shift their approach toward grid-scale storage rather than EV batteries.
Tariffs continue to reshape the U.S. storage market. Rising costs for overseas systems have created new incentives to integrate equipment domestically, and many developers are turning to US firms to assemble battery systems. Integration capacity can scale faster than battery cell manufacturing, but not without risk. Unlike cell plants, where automated processes keep variations in check, battery assembly and integration depends on people, as Jeff Zwijack from Intertek CEA explains.
