August 19, 2021: Australian integrated energy company AGL Energy has appointed Wärtsilä to supply a 250MW/250MWh battery storage system, the second largest in the country after Tesla’s Hornsdale Power Reserve, the company announced on August 9.
The Torrens Island installation, located near Adelaide, is the company’s first grid-scale storage project, and on completion will support thermal and renewable generating sources. The firm already operates the Torrens Island Power Station, which is the largest in South Australis. AGL says it is the first project in a planned roll-out of 850MW of batteries nationwide.
“The planning phase is well under way. With the support of the Australian government, we’ve been able to streamline the process, enabling us to bring the battery online sooner,” said chief operating officer Markus Brokhof.
Construction is planned for later this year, with the option to expand the battery by up to three hours (another 750MWh) at a later stage.
In January, AGL chose Wärtsilä as one of two suppliers for its storage plans, which include 200MW in Victoria and 200MW in New South Wales, as well as the Torrens Island project.
Separately, Wärtsilä on August 10 said it would supply a 5.2MW/5.2MWh energy storage system to Kaohsiung city in Taiwan for frequency regulation and spinning reserve services on the national grid.
“Frequency regulation will enable the integration of greater levels of renewables, while the Wärtsilä energy storage solution will support frequency stability and enhance the reliability of the system,” the company says.
Taiwan intends to generate 20% of its electricity from solar and wind power by 2025, with an additional 15GW of offshore wind to be installed by 2035.
