The Iberdrola Group has taken a further step in expanding its battery storage portfolio in New South Wales after securing a long-term contract for the 100MW Kingswood battery energy storage system (BESS) and officially opening the 65MW Smithfield facility.
New South Wales energy minister Penelope Sharpe attended the inauguration of the Smithfield project.
Iberdrola said the two developments will strengthen renewable energy integration, boost grid flexibility and improve the availability and efficiency of electricity supply across the state.
The Kingswood project will deliver 1080MWh of storage capacity, enabling at least eight hours of discharge and the ability to supply electricity to around 65,000 homes during peak demand periods. The scheme was recommended for approval by the New South Wales Department of Planning, Housing and Infrastructure in December 2025 and remains under assessment by the Independent Planning Commission.
Kingswood has also been selected for a long-term energy service agreement under the sixth round of state auctions held as part of the government’s Electricity Infrastructure Roadmap.
Meanwhile, Iberdrola Australia has completed and opened the Smithfield battery, which provides 65MW/130MWh of storage and was delivered ahead of schedule. The facility has its own long-term energy service agreement awarded in round two of the same programme and is capable of supplying around 20,000 homes.
Australia remains a strategic growth market for the Iberdrola Group, which plans to invest more than €1bn in the country between 2025 and 2028.
Iberdrola Australia currently operates more than 2GW of generation capacity either in operation or under construction, supplying clean electricity to approximately 400 commercial and industrial customers.
