U.S. grid-scale storage leaps 63%, residential storage 132%
The utility-scale energy storage sector added 4.9 GW in Q2, representing 63% year-on-year growth, while residential storage increased by 608 MW, said a report from American Clean Power Association and Wood Mackenzie. The United States had a record quarter for battery energy storage deployment in Q2 2025, adding 5.6 GW of installations, said a report […]
Deploy grid-forming batteries now to avoid costly infrastructure later, says ESIG
Large-scale batteries with grid-forming software can sustain grid reliability as renewables replace synchronous fossil generators, says an ESIG report. The report focuses on test procedures to validate grid-forming capabilities. In most large power systems, transmission grid operators are “still able to maintain grid reliability using synchronous generators present in their systems at this time,” notes a […]
Arbitrage remains leading use case for U.S. grid-scale batteries
Arbitrage has remained the dominant use case for utility-scale batteries in the U.S. through 2024. However, the share of the cumulative fleet reporting it as their primary application has stayed roughly the same percentage-wise. The latest data from the U.S. Energy Information Administration (EIA) confirms that arbitrage – the practice of buying electricity when prices […]
Telemetry could impact ERCOT’s rollout of real-time co-optimization with batteries
Projects that fail to upgrade their data infrastructure risk underperformance, delays, and lost trust with the network operator. From ESS News ERCOT is set to roll out its real-time co-optimization with batteries program (RTC+B), which could open up new value streams for batteries. But the rollout hinges on something deceptively simple: telemetry. “The real risk […]
