Construction starts on Waratah Super Battery

Project updates

Construction of the Waratah Super Battery - one of the most powerful batteries in the world at 850 MW/1680 MWh - commenced today on the site of the former coal-fired Munmorah Power Station.

Akaysha Energy, as System Integrity Protection Scheme (SIPS) Service Provider, is responsible for the construction and operation of the Battery Energy Storage System (BESS), which is expected to be completed before the earliest possible closure of the Eraring coal generator in August 2025.

The Waratah Super Battery Project is the first Priority Transmission Infrastructure Project (PTIP) to reach this milestone through processes established under the Electricity Infrastructure Investment Act 2020, with EnergyCo acting as the appointed Infrastructure Planner.

The Waratah Super Battery Project is designed to act as a 'shock absorber' in the event of any sudden power surges, including from bush fires or lightning strikes.

EnergyCo has played a crucial role in successfully attaining planning approval and shepherding the BESS from concept stage to the start of construction.

By choosing the site of the former Munmorah Power Station for the BESS, the NSW Government was able to repurpose a brownfield site and utilise existing connection infrastructure to accelerate the energy transition.
