Transgrid and EnergyCo sign contracts for Waratah Super Battery

The NSW Minister for Energy last week issued a formal direction to Transgrid as Network Operator to carry out the Waratah Super Battery Priority Transmission Infrastructure Project.

Energy Corporation of NSW Chief Executive James Hay and Transgrid Executive General Manager of Legal Governance and Risk Brian Salter signed the contracts in Sydney.

Transgrid CEO Brett Redman welcomed the contracts signing and EnergyCo’s confidence in the company to help deliver this critical infrastructure.

“I am delighted to commit in writing to playing our crucial role in delivering the Waratah Super Battery which includes connecting it to the grid via our existing Munmorah substation,” Mr Redman said.

“We are pleased to have been asked to work with EnergyCo to deliver the project as the first Priority Transmission Infrastructure Project under the Electricity Infrastructure Investment Act.

“The super battery will be critical to secure energy supply after Eraring’s closure and before completion of major transmission upgrades to enable energy produced in new renewable energy zones to be utilised across the grid.

“Transgrid will deliver $150 million in upgrades to our existing transmission lines and substations and a $30 million System Integrity Protection Scheme (SIPS) to control the super battery’s activation as required.

“We are pleased to partner with EnergyCo, the battery service provider and existing and future generation facilities to carry out this important project for the security of energy supply in NSW.

“Transgrid is fully committed to working with the NSW Government to ensure a more reliable, affordable and sustainable network and accelerate our transition to a clean energy future.”

The super battery, SIPS control and network upgrades are expected to be completed by mid-2025 in advance of Eraring’s earliest closure date.
