Apex Clean Energy and Powin LLC are working on a pair of new battery storage projects in Texas: Angelo Storage, co-located with the 195 MW Angelo Solar Project, and Great Kiskadee Storage.
Apex developed and builds, owns and operates the projects, each delivering 100 MW/200 MWh of capacity to the Texas grid with two hours of battery life. Powin offers the Centipede platform and StackOS battery management system.
StackOS provides energy arbitrage and peripheral grid services to the ERCOT market, which are critical to maintaining grid reliability. Storage systems absorb excess solar or wind production when demand is low and discharge when energy use is high, ensuring adequate power supply and allowing the grid to operate more efficiently and flexibly.
“As Texas experiences more extreme weather in both the summer and winter months, the need for cleaner, more reliable energy increases,” said Geoff Brown, CEO of Powin. “With visibility and control down to the battery cell level, our platform can respond to changing grid conditions in real-time. When these new storage projects go live, ERCOT customers in the region will be assured of a climate-resilient power grid that supports Powin’s technology.
“Texas already leads the country in terms of wind and solar power capacity; adding battery storage will support ERCOT with grid reliability, encouraging further renewable energy development in the Lone Star State,” adds Mark Goodwin, CEO of Apex. “Battery storage is a key part of our country’s energy transition, and Apex is investing accordingly, and our development portfolio is 11.6 GW of storage space.
Together, the projects will generate more than $24.4 million in tax revenue and approximately 100 jobs during construction.
