APEX & POWIN CASE STUDY

TEXAS GRID BOLSTERED BY
500MWH ENERGY STORAGE ADVANCEMENT

The Texas grid is an outlier in many ways. Not only is the state one of the leaders in wind-powered electricity generation, but its grid remains disconnected from neighboring states. This means Texas has to be self-sufficient and cannot rely on energy from nearby grids.

This is why in the face of extreme weather events, grid resilience and reliability have become top priorities for Texas. And that’s where a new collaboration between Powin and Apex Clean Energy comes in. When completed, these energy storage projects will add much-needed capacity to the already strained Texas grid.

WHEN IT’S NEEDED MOST

The Angelo Storage and Great Kiskadee, as the projects are known, will be located in Tom Green County and in Hidalgo County, respectively. Each of these projects is expected to deliver 100MW/200 MWh of capacity to the Texas grid with a 2-hour battery duration. The projects are expected to be operational in 2024.

MEETING ENERGY NEEDS
IN REAL-TIME, TOGETHER

As part of this collaboration, Apex will be responsible for developing, constructing, operating, and maintaining the projects. Powin will supply the Stack750 Integrated Platform and StackOSTM battery management system.

In addition to supplying energy arbitrage and ancillary grid services to the Texas grid, Powin’s StackOS platform is designed to provide visibility and control down to the battery cell level. This makes it easy to respond to changing grid conditions in real-time.

These energy storage projects will add both flexibility and resilience to the grid. The storage systems are designed to absorb excess solar or wind energy when demand is low and discharge when energy usage is high. This will ensure the grid can meet growing demand without failing, even during extreme weather events.
