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 approximately 80km west of Mackay.

The project team is prioritising progressing the PHES and is currently undertaking field, environmental and technical studies on the proposed PHES which is expected to commence construction in 2026 and be operational in 2031.

The site is located on two large rural landholdings in the Mackay Hinterland on Widi Country, downstream of Sunwater’s existing Eungella Dam. It is a proposed 1.4GW energy hub that, when fully operational, will deliver dispatchable green energy into the grid to power an estimated 900,000 Queensland homes.
