Apex’s Great Kiskadee Storage Launches Commercial Operations

100 MW Battery Storage Facility Enhancing Grid Reliability in ERCOT Market

CHARLOTTESVILLE, Va.--(BUSINESS WIRE)--Apex Clean Energy today announced that Great Kiskadee Storage, a 100 MW/200 MWh utility-scale battery facility with a two-hour duration, has reached commercial operations. The project represents the first operational asset of SA Grid Solutions, a joint venture between Apex and SK Gas and SK eternix established in early 2024.

“Great Kiskadee Storage marks a significant milestone in our partnership with SK Gas and SK eternix, demonstrating the strength of our collaboration and shared commitment to advancing energy storage solutions,” said Ken Young, CEO of Apex Clean Energy. “This facility will play a crucial role in enhancing grid reliability in Texas, absorbing excess electricity during periods of high generation and providing power back to the grid when demand increases.”

Great Kiskadee, located in Hidalgo County, Texas, marks the first of multiple Apex storage assets planned for the joint venture as the partners work to accelerate the deployment of utility-scale battery storage. The next project slated for purchase by the JV is of similar size and duration. Apex will manage the development, construction, operations, and optimization of current and future facilities.

The facility, constructed by Saber Power Services, will help stabilize the Texas grid while creating significant local economic benefits, including more than $12.6 million in tax revenue over its lifetime. Additionally, the project has committed grant funding to support the restoration of 200 acres of wetland within the Laguna Atascosa National Wildlife Refuge, enhancing habitat for migratory waterfowl, bats, and other species.
