Renewable energy developer Ampyr Australia is seeking an investor for a 400MW/1,000MWh battery energy storage system (BESS) in New South Wales, Australia.
According to Australian Financial Review (AFR) reports, the organisation has tasked advisory firm Azure Capital to introduce potential equity partners in the Wellington BESS.

The Wellington BESS is located 3km northeast of the town whose name it derives from. Wellington is located in the Central Western Slopes, at the junction between Wambuul Macquarie and Bell Rivers. It is around 362km northwest of the state capital, Sydney.
Earlier this year, Energy-Storage.news reported that Ampyr Australia had secured Shell Energy Australia’s remaining 50% stake in the BESS project. This was for the project’s first stage, comprising 300MW/600MWh BESS, whilst the second stage, already owned by Ampyr, will increase this by 100MW/400MWh.
The two companies launched a joint venture in 2022 to develop the 1GWh Wellington BESS, which will connect to an existing substation of high-voltage transmission system operator and manager Transgrid at Wellington and be adjacent to Central-West Orana Renewable Energy Zone (REZ).
This REZ is set to be the first in Australia to enter construction later this year, with the state-owned Energy Corporation of New South Wales (EnergyCo) having granted access rights for 7.15GW of projects earlier this month.
The AFR report added that the exact deal structure and bidding timetable are yet to be set.
Ampyr Australia is targeting an operational portfolio of 3GW of energy storage in the country by 2030. Its Singapore-headquartered parent company, Ampyr Energy, is developing around 12GW of projects globally.
Copenhagen Infrastructure Partners seeks buyer for 960MWh BESS
Elsewhere, a separate report from the AFR has said that Danish institutional investor Copenhagen Infrastructure Partners (CIP) is seeking a buyer for its 240MW/960MWh Summerfield BESS in South Australia.
Like Ampyr, CIP has contracted Azure Capital to find a buyer for the BESS, which entered construction at the start of 2025 and is expected to be fully operational by the end of this year.
According to the AFR, CIP is seeking bids for up to 100% of the asset. The BESS is located in Summerfield, in South Australia’s Murrayfields region, and close to existing transmission infrastructure in the Australian state.
CIP inked a 10-year offtake agreement for Summerfield with ASX-listed Australian utility company Origin Energy, and a final investment decision (FID) was made on the project in September last year.
The system will charge with surplus renewable energy during off-peak times and inject power into the grid when demand peaks, supporting the electricity networks in South Australia and neighbouring Victoria.
CIP also said the project will support South Australia’s policy goal of achieving 100% net renewable energy by 2027, the year Summerfield will go into commercial operation.
Energy-Storage.news has reached out to Copenhagen Infrastructure Partners and Ampyr for confirmation of the Australian Financial Review reports and will update this story on receipt of responses.
