Energy Vault Holdings has commenced construction of a 200-megawatt/2-hour battery energy storage system for ACEN Australia’s New England Solar project.

The system is the first of two deployments planned for the 720-MW solar project in New South Wales (NSW), the grid-scale energy storage company said in a news release Feb. 24. The move is expected to help stabilize the grid while reducing reliance on coal-fired power generation.

“New England Solar will serve as a critical source of renewable energy for the NSW region, and Energy Vault’s involvement is reflective of the company’s truly global approach to meeting the growing demand for reliable and cost-effective energy storage solutions.”

For the project, Energy Vault said it will use a special inverter which enables advanced grid support functionalities such as voltage and frequency ride-through, grid support during disturbances and reactive power control.

ACEN’s New England Solar is being built in stages near Uralla in NSW.
