The local renewable energy arm of South Korean electronics giant Samsung is seeking a green light from the federal government for a new solar-battery hybrid project in southern New South Wales that would offer up to four hours of energy storage.

Plans for the Boro Solar Farm this week joined the queue for environmental assessment under the federal EPBC Act, seeking to install up to 150 megawatt (MW) of solar and a 250 MW, 1,000 megawatt-hour (MWh) battery energy storage system about an hour east of Canberra.

The site for the proposed project is roughly 40 km south of Goulburn and 200 km south-west of Sydney, in the local government areas of Goulburn Mulwaree Council and Queanbeyan-Palerang Regional Council in the South East and Tablelands Region of NSW.

Developer Samsung C&T Renewable Energy Australia says the proposed project area covers around 420 hectares of land that has been extensively cleared and used for farming and agriculture practices, and notes a history of mining activity for gold, silver, copper, lead and zinc in the region.

“The solar Farm would involve the construction, operation and decommissioning of a solar farm and battery energy storage system (BESS) with a generating capacity of 400 megawatts (up to 150 megawatt solar farm and a 250 megawatts/ 1000 megawatt hours storage BESS),” the proposal says.
