TARONG BATTERY ENERGY STORAGE SYSTEM

ICON BATTERY REVERSED

Overview

The Tarong Battery Energy Storage System (BESS) will provide essential firming capacity to support the renewable projects we have planned in Southern Queensland. It will have a storage capacity of 300MW over two hours duration. The Tarong BESS will be the first battery energy storage in Stanwell's portfolio.

Batteries can be charged when energy generation is high, and discharge energy back into the grid when generation is low or demand is high, or to maintain grid stability. This system can charge and discharge electricity several times a day and can respond within fractions of a second to electricity demand.

Construction of the BESS onsite at the Tarong power station is the first step in the transition of this site into a clean energy hub and is being built in two stages. A total of $514 million is being invested in this first battery project.
