Waratah Super Battery

Waratah Super Battery

To ensure NSW continues to have reliable energy supply following the anticipated closure of the Eraring Power Station, the NSW Government will procure a 700MW standby network battery, 'the Waratah Super Battery', dedicated to support the transmission grid.

The battery will act as a “shock absorber” – absorbing any sudden power surges including those from a bushfire or lightning strike – to help secure the State’s energy future as part of the Electricity Infrastructure Roadmap.

The Waratah Super Battery will be the largest standby network battery in the Southern Hemisphere and together with other minor transmission upgrades, will allow Sydney, Newcastle and Wollongong consumers to access more energy from existing electricity generation.

Competitive procurement process - indicative timeline

EnergyCo has launched a competitive procurement process to identify suitable battery developers and appropriate site(s) for the development of the Waratah Super Battery. See indicative timeline below:

  • Mid 2022 Invitation to Tender (ITT)
  • Late 2022 Enter into Applicable Contract(s)
  • As early as Q4 2024 In-Service Date

Virtual Market Forum

EnergyCo held a virtual Market Forum on 31 March 2022 at 10am to provide interested parties with an overview of the project and the competitive battery developer procurement process. This process is distinct from, and separate to, the various Renewable Energy Zone procurement processes that EnergyCo is currently undertaking.

Expression of Interest (EOI)

The Waratah Super Battery Expression of Interest (EOI) document was issued to qualified registered parties on 4 April 2022. The EOI deadline has now passed and EnergyCo has evaluated those submissions.

Waratah Super Battery - Munmorah

One of the sites being considered for development of the Waratah Super Battery is within the former Munmorah Power Station at 301 Scenic Drive Colongra (the Munmorah Site).

EnergyCo is now preparing a comprehensive Environmental Impact Statement (EIS) for the proposal, which will assess the impacts of the Waratah Super Battery on the environment and surrounding communities.

As part of the preparation of the EIS for development of the Waratah Super Battery at Munmorah, EnergyCo is consulting with a range of stakeholders who may have an interest in the proposed development, including residents in the surrounding community.
