Alinta Energy has received approval for the construction of a second battery storage facility in Wagerup, Western Australia.

The project, located in the Shire of Waroona, will have a capacity of 300 megawatts (MW) and is designed to support the integration of more renewable energy sources into the state’s electricity network.

The approval grants Alinta Energy permission to develop the 300 MW battery energy storage system along with associated infrastructure, including transformers, high-voltage cabling, a switch room, control room, internal access roads, and other necessary equipment.

This new battery project will complement Alinta’s existing 100 MW two-hour battery currently under construction in the same area.

Alinta said the project aims to enhance system security and stability as Western Australia continues to increase its reliance on intermittent renewable energy sources, particularly solar power.

By providing quickly dispatchable energy, the battery will help manage fluctuations in the electricity market and maintain grid reliability.

Alinta Energy views this project as aligned with its sustainability goals, focusing on delivering lower-emission energy that is both reliable and affordable.

“We’re thrilled that this project – our second battery in the Peel region – has been approved,” Russell Slaughter, Head of Project Development said.

“With the continued increase of intermittent energy sources into the state’s main electricity network, the need for dispatchable energy sources that can react quickly to changes in the electricity market is increasing.”

“Our second battery will support the introduction of more solar and other intermittent renewable energy sources into the existing network by maintaining system security and stability.”

The 300MW Wagerup battery project is expected to be completed by October 2027.
