About the Capricornia Energy Hub

The Capricornia Energy Hub is a proposed pumped hydroelectric energy storage facility (PHES), proposed wind farm and proposed solar farm.

Located on two large rural landholdings in the Mackay Hinterland on Widi Country, downstream of Sunwater’s existing Eungella Dam, it is a 1.4GW energy hub that, when fully operational, will deliver dispatchable green energy into the grid to power 1.5 million Queensland homes.

Ideally located in North Queensland Renewable Energy Zone, the project will also include two water reservoirs, connecting waterways, one underground powerhouse and 18 km of new transmission lines. The Capricornia PHES will connect to the existing high voltage transmission line from Strathmore to Nebo via a substation and 18km of new transmission line. 

The Hub is expected to be operating by 2031 and will bring sustainable industry and employment to the region.

Capricornia PHES will create opportunities for local businesses and contractors – approximately 600 jobs during peak construction, and 65 local jobs during operation. Capricornia PHES will play an important role in Queensland’s future energy mix and help contribute to secure, reliable, and affordable energy.
