250 MW battery storage system planned for Australia
Project called second largest network-wide BESS project in the country
Wärtsilä will supply a battery energy storage system (BESS) to AGL Energy, one of Australia’s leading integrated energy companies.
The 250 MW / 250 MWh system will be installed on Torrens Island in South Australia. This will be the first BESS project across the AGL network and the second in Australia. Once installed, the system will support a broad portfolio of generating assets, both thermal and renewable, and help Australia decarbonise and move to a 100% renewable energy future.
AGL is an integrated provider of essential services with a power generation capacity of over 11,000 MW, which represents approximately 20% of the total generation capacity within the Australian National Electricity Market (NEM).
The order of more than 100 MEUR is the first placed under a framework agreement signed between Wärtsilä and AGL in 2020 for the supply of energy storage projects. AGL provides up to 1 GW of grid-wide energy storage across Australia, a country of unparalleled renewable energy resources. The flexible capacity provided by Wärtsilä’s advanced BESS provides an efficient way to balance energy supply from renewable sources, thus maintaining grid stability and reliability. Energy storage technology will play a key role in the Australian energy sector’s transition from conventional fossil fuels to cleaner renewable energy.
“This is a historic project and we are proud to have been selected as an ESS supplier. Renewable power generation is developing rapidly in South Australia, and the flexibility of our technology and the in-house experience we bring, can help maintain a reliable and affordable electricity supply for South Australian consumers – households and consumers. companies – for years to come, ”said Sushil Purohit, President of Wärtsilä Energy.
The Torrens Island system will be delivered by Wärtsilä on a full Engineering, Procurement and Construction (EPC) basis, and designed to provide network support capabilities to AGL’s portfolio of assets. It should be operational in early 2023.
The Wärtsilä system will initially operate in network monitoring mode before subsequently switching to network formation mode (virtual synchronous generation – VSG), making it the largest energy storage solution capable of operating in this mode. This will allow very fast response times and ensure the sustainability of the Torrens Island installation. The complex solution is supported by the advanced power plant controller GEMS and energy management software from Wärtsilä.
Wärtsilä has already supplied a 211 MW power plant for AGL, the Barker Inlet Power Plant, also located on Torrens Island. The plant operates with 12 Wärtsilä 50DF multi-fuel engines running on natural gas. The hybrid combination of gas combustion engines and energy storage will play an increasingly important role in Australia’s energy future.
