AMPYR Australia has secured funding above A$340m ($221m) for its 300MW/600 megawatt hours (MWh) Wellington Stage 1 battery energy storage system (BESS) project in regional New South Wales (NSW), Australia.
Scheduled to be operational by 2026, the project will boost the supply of dependable renewable energy across Australia while reducing electricity costs for emerging industries.
The financing package is supported by banking institutions the Bank of China, the Commonwealth Bank of Australia, HSBC, Rabobank, Société Générale and the United Overseas Bank.
AMPYR is also engaging with local Aboriginal communities around Wellington, offering investment opportunities in parallel with their ventures into sustainable projects.
AMPYR aims to deliver more than 6 gigawatt hours (GWh) of energy storage projects by the end of 2030. This goal includes both stages of the Wellington project, with stage 2 adding a further 100MW/400MWh to reach a combined 1GWh capacity in the region by 2027.
Supporting this development is a ten-year virtual power purchase agreement (PPA) between AMPYR and ZEN Energy Retail for 150MW of the projects’ output.
