Akaysha Energy has signed a long-term service agreement for its Ulinda Park battery energy storage system in Queensland that will help the big battery to meet its market and regulatory obligations, including the requirements of the federal government’s Capacity Investment Scheme.
Hitachi Energy announced on Wednesday that it has signed a 20-year service agreement with Akaysha for the 155 megawatt (MW), 298 megawatt-hour (MWh) Ulinda Park battery energy storage system (BESS), the first phase of which was brought online in December 2025.
Located adjacent to the Western Downs Substation near Hopeland, the battery aims to facilitate the rapid expansion of wind and solar capacity across the region, including through a second stage that will take it to 350 MW and 1,078 MWh.
In mid-2023, Akayasha announced that it had underpinned the first stage of the Ulinda project with a “first of its kind,” 10-year revenue swap and risk hedging deal that will allow it to keep operational flexibility to optimise its bidding across energy and frequency control markets.
For the second stage of Ulinda Park, which will expand the battery’s capacity by a further 195 MW and 780MWh, Akaysha has been awarded a contract through federal Labor’s Capacity Investment Scheme.
