OX2 has received EPBC approval, Australia’s central piece of environmental legislation, to build the 135 MW Muswellbrook solar and storage project by an old coal mine in New South Wales.

The project site is adjacent to the Muswellbrook Coal Mine, which ceased operations in 2022, on land primarily owned by mine operator Idemitsu Australia. The project forms part of a broader vision to redevelop the former mining site into a hub for industrial and energy innovation. The project is developed together with Idemitsu and already holds development approval.

“This is a leading example of the transition of the Upper Hunter Valley from coal mining to innovative post-mining land uses. The Muswellbrook solar project is an early mover in the re-purposing of a coal mine into an energy generation site and serves as an important test case for the broader region,” says Catherine Way, Director of Development, OX2 Australia.

Muswellbrook is the second OX2 project in Australia to receive EPBC approval. The 90 MW Summerville solar and storage project, also in New South Wales, received its EPBC approval in July.

“I’m proud to see the continued progress of our projects in Australia. These approvals reflect the strength and professionalism of our team, as well as the growing momentum behind renewable energy across the country,” says Stephen Symons, Country Manager, OX2 Australia.

OX2’s portfolio in Australia currently includes 3.7 GW of solar, wind, and storage projects under development and construction. OX2 also provides management services for renewable energy assets, with 390 MW currently under management in Australia.
