BESS – Reliable Energy Supply.
This Battery Energy Storage System is designed to deliver 693 MW / 1,386 MWh of fast, flexible energy storage to support grid resilience, renewable integration, and large-load development in Central Texas.
A Grid-Scale Energy Asset Built for Flexibility.
This Central Texas BESS installation will be utility-scale 693 MW / 1,386 MWh battery energy-storage facility designed around Tesla Megapack technology.
The project is expected to connect through a 34.5 kV collection system and collector substation to a 345 kV transmission system—creating a major dispatchable-energy resource for reliability, renewable integration, and future large-load growth.
Built for a More Resilient Grid.
GRID RESILIENCE
Provide fast, controllable stored energy to help stabilize grid performance and improve operational reliability.
FLEXIBLE DISPATCH
Store energy during low-demand or high-renewable periods and discharge it during peak demand or system constraints.
LARGE-LOAD READY
Support future data-center and other high-load development with a responsive, utility-scale energy asset.
RENEWABLE INTEGRATION
Help make variable renewable generation more useful by shifting energy to when the grid needs it most.
