## Utility-Scale BESS for Frequency Regulation

The procurement covers 1000 MW of power capacity with 4 hours of storage duration connecting directly to 380 kV transmission substations.

The systems will provide rapid frequency response, dynamic voltage support, and energy arbitrage to smooth daily solar fluctuations.

## Grid-Forming Inverter Capabilities

Developers must incorporate grid-forming inverter controls capable of responding within 20 milliseconds to sudden frequency dips.

This synthetic inertia deployment ensures transmission network stability as conventional thermal generation is displaced by renewables.
