Australia’s Largest Solar-Battery Hybrid Project Gets Grid Connection Approval
Ark Energy, an Australian company specialising in renewable energy development and operations, has announced that it has attained grid connection approval for its Richmond Valley solar farm and battery project. This venture is poised to become the largest of its type in the country.
The approval consists of 5.3.4.A/B letters that confirm the project adheres to the Generator Performance Standards. It has received the go-ahead from the Australian Energy Market Operator (AEMO) and the transmission network service provider Transgrid, enabling it to connect to the local 330 kV network through a planned switching station.
Project Features and Phased Development
The Richmond Valley development is being implemented in stages, ultimately targeting a capacity of 500 megawatts (MW) of solar energy along with up to 475 MW battery power capability, featuring eight hours of energy storage, equating to 3,800 megawatt-hours (MWh).
The inaugural phase will encompass a 200 MW solar farm and a 275 MW battery energy storage system (BESS) with a capacity of 2,200 MWh, with construction slated to commence later this year. The technology used for the battery will incorporate lithium-iron phosphate (LFP) chemistry.
Approval Process and Future Impact
The successful approval for the grid connection application followed a thorough testing process. This included design modifications, extensive power system modelling, numerous simulations, and detailed network studies and workshops.
Expressing enthusiasm about the achievement, Ark Energy’s CEO, Michael Choi, stated, “We are thrilled to secure grid connection for the Richmond Valley Solar Farm & BESS. This milestone brings us closer to achieving financial closure on the project and progressing to construction in the upcoming months.”
Choi further described the project as pivotal for Ark Energy, emphasising that its operation will substantially enhance electricity supply and contribute to grid stability in New South Wales and the National Electricity Market (NEM).
