grid-scale storage
Global battery industry grows 83% in last five years, boosting deployment to over 300 GW
According to a new report from Intertek CEA, over 70% of the global energy storage market share is held by just five players. From ESS News Over 300 GWh of battery energy storage systems were shipped globally last year, according to Intertek CEA’s Q3 2025 reports on energy storage supply, technology, policy and pricing, and the industry’s […]
Startup unveils zinc-polyiodide redox flow battery with energy density of 320 Wh/L
BESSt announced that its new redox flow battery technology delivers 20 times the energy density of conventional vanadium flow storage systems. The battery is based on a zinc–polyiodide redox flow chemistry developed by the Pacific Northwest National Laboratory. From ESS News US-based startup BESSt has launched a new redox flow battery technology that reportedly achieves 20 […]
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 […]
Flatiron Energy secures $540 million for largest battery project in Massachusetts
The company is expected to bring a 200 MW / 800 MWh battery to commercial operations by late 2026. Flatiron Energy secured approximately $540 million in financing commitments for the Taft battery project in Uxbridge, Mass. The standalone battery project will be the largest in Massachusetts planned to be 200 MW, 800 MWh. Site preparations […]
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 […]
