Swedish independent power producer (IPP) OX2 has confirmed it has started construction activities at the 100MW/300MWh Muswellbrook solar-plus-storage site in New South Wales (NSW), Australia.
The project, which combines 300MWh of battery energy storage systems (BESS) with a 135MW solar PV power plant, will cover 482 hectares in the Hunter Central Coast Renewable Energy Zone of New South Wales on land “formerly associated with coal mining operations,” according to the company.
Building work will involve the construction of 2.4km of new overhead wires to connect to the state’s electricity grid and the National Electricity Market (NEM) via a connection to a 132kV transmission line owned by electricity distribution company Ausgrid. OX2 expects to complete construction in 2028.
