Energy storage provider Fluence Energy Inc. will deliver a 300 megawatt (MW) / 650 MWh battery for Australia-based Origin Energy at the Mortlake Power Station in Victoria’s southwest Renewable Energy Zone, the company announced Jan. 29.

Origin awarded Fluence with a 15-year service agreement for Fluence’s Gridstack energy storage system to capture excess power during periods of high renewable generation and discharge to meet peak demand.

The system will also use Nispera, Fluence's AI-powered asset performance management software, to optimize the battery's operational performance.

Site preparation and civil works of the Mortlake battery will begin following a design and procurement stage for the project. The energy storage system is expected to be commissioned in late 2026.
