Fluence Chosen for Ampyr’s 300 MW BESS in Australia

Fluence Energy, a global intelligent energy storage services and asset optimization software provider, was selected by AMPYR Australia (AMPYR) to supply a 300 MW / 600 MWh Wellington Stage 1 Battery Energy Storage System (BESS) in Wellington, New South Wales, Australia. AMPYR has contracted Fluence for the construction of this project and a 20-year service and maintenance contract. Fluence currently has four battery energy storage systems (BESS) in operation, another two entering operation in the next few months, and several BESS projects under construction.

The project will also be powered by Fluence’s Mosaic bidding software and Nispera asset performance management software. The Wellington Stage 1 BESS is AMPYR’s first grid-scale battery energy storage system to reach financial close in Australia. This project is scheduled to be commissioned in 2026, thereby supporting Australia’s renewable energy capacity and grid stability. Wellington Stage 1 will use Fluence’s Gridstack™ grid-scale energy storage product, underpinned by Fluence’s technology.

The system will be optimized by Mosaic, Fluence’s intelligent, AI-powered bidding software, to enhance the efficiency and profitability of BESS in the National Electricity Market (NEM) and Nispera. Fluence’s asset performance management software Mosaic, will be used to manage AMPYR’s virtual tolling contract, which will allow AMPYR to nominate when the battery should charge or discharge, to maximize performance.

Leadership View

Jan Teichmann, SVP & President, APAC, said, “We believe the full suite of Fluence’s innovative storage products and operational services will allow AMPYR to extract the most value out of the Wellington BESS once operational.”

“Our partnership with Fluence will enable the delivery of competitively priced, reliable renewable energy to major Australian electricity users. This project is a crucial first step in our commitment to delivering 6,000 MWh of operational BESS by 2030, directly addressing the growing need for grid-scale batteries and accelerating Australia’s transition to a reliable, affordable, and renewable energy future,” said AMPYR Australia CEO Alex Wonhas.
