Fluence to power AMPYR Australia’s 300 MW Wellington BESS with 20-year service deal
Fluence Energy, Inc. (NASDAQ: FLNC), a global leader in smart energy storage systems, has been selected by AMPYR Australia to deliver the 300 MW / 600 MWh Wellington Stage 1 Battery Energy Storage System (BESS) in Wellington, NSW, with construction and long-term operations already confirmed.
This grid-scale battery marks AMPYR’s first energy storage project to reach financial close in Australia and is expected to be energised in 2026. It represents a pivotal investment toward advancing renewable energy reliability and grid stability across the National Electricity Market (NEM).
AI-driven software to optimize battery performance
The project will be powered by Fluence’s Gridstack™ solution, designed for utility-scale energy storage. To optimize system performance, Fluence will integrate Mosaic, its AI-powered bidding software that intelligently manages energy dispatch for maximum market participation. This includes AMPYR’s virtual tolling contract, allowing them to nominate charge and discharge schedules.
In addition, Nispera, Fluence’s asset performance management platform, will monitor system health, increase uptime, and deliver key insights to maximize returns over the 20-year operational period covered in the service agreement.
“We are thrilled to be partnering with AMPYR on the Wellington Stage 1 BESS project, marking another step forward in strengthening Australia’s transition to a more sustainable energy future,” said Jan Teichmann, SVP & President, APAC at Fluence.
AMPYR aims for long-term impact with national energy goals
According to AMPYR Australia CEO Alex Wonhas, the Wellington Stage 1 project is just the beginning. With a broader target of 6,000 MWh of operational BESS by 2030, AMPYR intends to play a major role in meeting Australia’s energy storage and decarbonization goals.
“This is the first milestone in our mission to deliver large-scale energy storage to meet growing grid demands. Wellington BESS brings us closer to delivering reliable and affordable clean energy to Australians,” said Wonhas.
Fluence continues to strengthen its BESS portfolio in the country, with four battery systems currently in operation, two more coming online soon, and several additional projects under development. The Wellington Stage 1 BESS will significantly enhance New South Wales’ ability to integrate renewables and manage grid fluctuations.
