Apex Clean Energy is to build two 100MW energy storage projects in Texas, using technology from Powin.
The Angelo and Great Kiskadee storage projects are expected to begin commercial operations in late 2023 and 2024.
Apex, which developed the projects, will construct, own and operate them, incorporating Powin’s technology, including its battery management system.
The Angelo storage project, co-located with the 195MW Angelo solar farm, and the Great Kiskadee storage project will each have a two-hour battery duration.
The battery systems will use Powin’s StackOS platform to provide energy arbitrage and ancillary grid services to the ERCOT market, to maintain grid reliability.
The storage systems will absorb excess solar or wind generation when demand is low and discharge when energy usage is high, ensuring adequate power supply while allowing the grid to operate more efficiently and flexibly.
“As Texas experiences more extreme weather conditions in both summer and winter months, there’s a growing need for cleaner and more reliable energy,” 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. As these new storage projects are deployed, ERCOT customers in the region will have the assurance of a climate-resilient grid backed by Powin’s technology.”
Apex CEO Mark Goodwin added: “Texas already leads the nation in operating wind and solar capacity; adding battery storage will support ERCOT with grid reliability, encouraging additional renewable development in the Lone Star State.
“Battery storage is a crucial component of our nation’s energy transition, and Apex is investing accordingly, with 11.6GW of utility-scale storage in our development portfolio – gigawatts of clean energy potential that is only realised alongside experienced partners like Powin.”
Together, the projects will generate more than $24.4 million in tax revenue and approximately 100 jobs during construction.
