Newsom vetoes another bill to curb California’s rising energy demand
Gov. Newsom said the virtual power plant bill would not have improved electric grid reliability planning because it did “not align with the California Public Utility Commission’s Resource Adequacy framework.” Gov. Gavin Newsom vetoed AB 740, a bipartisan bill that would have required California to adopt a virtual power plant (VPP) deployment plan. Newsom said […]
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 […]
Zombie apocalypse-ready solar + storage kit
JDEnergy introduced its eBlock 100C, eStation MV-6880, combined control systems, and the milestone deployment of its 20,000th energy storage block. Exhibiting at its booth at the RE+ trade show, battery integrator JDEnergy focused on the gear: specifically, how its products integrate, how they’re installed, and how control systems can be streamlined by removing unnecessary components. […]
Solar-plus-storage project decarbonizes industrial processes in Texas
A BASF industrial facility that produces raw materials for diapers, fertilizers, food packaging carpets and more is now powered by a 72 MW solar project with onsite energy storage. X-Elio launched operations at its Liberty Energy project in Dayton, Texas. The 72 MW solar and 60 MW, 120 MWh battery energy storage system is the […]
California allows flexible interconnection for distributed solar, storage to avoid grid upgrades
California is the first state to enable distributed solar or storage projects to use flexible interconnection, but the hardware required to flexibly control output may not yet be available. A flexible interconnection option for distributed solar or storage in California that was long in the works has now taken effect. The option will enable projects […]
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 […]
California hybrid hydrogen fuel cell and battery storage facility is now online
The Calistoga Resiliency Center offers long-duration emergency microgrid services during service interruption from wildfires and severe weather events with a combination of hydrogen fuel and lithium-ion batteries. A 293 MWh hybrid hydrogen fuel cell and battery-based energy storage system (BESS) facility has become operational north of San Francisco, Calif. The Calistoga Resiliency Center, a joint […]

Newsom strikes down bill to help reduce electric demand despite unanimous approval
Gov. Newsom said the bill would not have improved electric grid reliability planning because it did “not align with the California Public Utility Commission’s Resource Adequacy framework.” Gov. Gavin Newsom vetoed a bill to provide demand-side electricity savings after it sailed through the state’s Assembly and Senate, with all 119 voting lawmakers unanimously approving the […]
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 […]
