Overview

The Stanwell Battery Energy Storage System (BESS) will provide essential firming capacity to support the renewable projects we have planned in Central Queensland. At 300MW capacity and four hours storage duration, it is the largest committed battery project in Queensland.

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 Stanwell Power Station is the first step in the transition of this site into a clean energy hub. A total of $747 million will be invested in this project, $448.2 million from the Queensland Renewable Energy and Hydrogen Jobs Fund.
