The Iberdrola Group has progressed its storage strategy in New South Wales after securing a long-term contract for the 100MW Kingswood battery and opening the 65MW Smithfield facility.
Penelope Sharpe, the state’s energy minister, attended the Smithfield inauguration.
The company said both projects will strengthen renewable integration, increase grid flexibility and improve the availability and efficiency of supply.
Kingswood will reach 1080MWh of storage, allowing at least eight hours of discharge and the ability to supply around 65,000 homes at peak times.
The New South Wales Department of Planning, Housing and Infrastructure recommended approval in December 2025 and the project remains under assessment by the Independent Planning Commission.
The battery has been selected for a long-term energy service agreement under the sixth round of state auctions within the government’s electric infrastructure roadmap.
Iberdrola Australia has also opened the Smithfield battery, which has 130MWh of storage and was completed ahead of schedule.
The project has its own long-term energy service agreement awarded in round two of the same programme and can supply 20,000 homes.
Australia is a strategic market for the Iberdrola Group, which plans to invest more than €1bn in the country between 2025 and 2028.
Iberdrola Australia operates over 2000MW of generation capacity in operation or construction, supplying clean energy to about 400 commercial and industrial customers.
