Technology group Wärtsilä has a signed a deal to supply a 350MW/1,474MWh lithium-ion energy storage system (ESS) to Australian power supplier EnergyAustralia.
The ESS will provide grid-stability services, such as frequency balancing during peak demand, and support the integration of renewable energy onto the grid.
The system will use the Finnish-based company’s Quantum High Energy ESS technology and its GEMS Digital Energy Platform software.
Building work on the system is due to begin this year and end in 2027. It will be built next to EnergyAustralia’s gas-powered Jeeralang Power Station.
This is the first time Wärtsilä has supplied a system for use in the state of Victoria. Once finished, it will bring Wärtsilä’s footprint in Australia to 4.8GWh across seven projects.
The deal was signed in Q4 last year, and includes engineering design, supply, commissioning, and a 15-year service agreement. EnergyAustralia’s managing director, Mark Collette, said the project was the largest single project investment made by the company.
When completed, the system will deliver power to EnergyAustralia’s Wooreen Energy Storage System (WESS). The system is designed to deliver 350MW for four hours (enough for around 230,00 homes) and is due to be commissioned before the end of 2026.
