The milestone follows a development timeline that Ark Energy completed in four years.
New South Wales planning approval was granted in October 2025, federal environmental clearance under the EPBC Act followed in December 2025, and grid connection approval from AEMO and transmission network provider Transgrid was secured in June 2026.
Richmond Valley was also highlighted at the time as among the first hybrid solar-plus-storage projects in the National Electricity Market (NEM) to operate through a single point of connection using grid-forming inverter technology.
The full approved configuration extends to 435MW of solar and a 475MW/3,148MWh BESS.
The project holds a Long-Term Energy Service Agreement (LTESA) under the NSW Electricity Infrastructure Roadmap and is listed on the Australian government’s National Renewable Energy Priority List.
