Under Procurement
Capricornia Energy Hub Pumped Hydro

The Capricornia Energy Hub Pumped Hydroelectric System is a proposed 750-megawatt (MW) pump and generation facility. The project would have the capacity to dispatch this power over 16 hours, giving the facility a total storage capacity of 12 gigawatt hours (GWh) and a water transfer volume of 18.1 gigalitres (GL).

The project site is to be located approximately 80 km west of Mackay in North Queensland, approximately 10 km west of Eungella and near the existing Eungella Dam.

The project is owned by Cophenhagen Infrastructure Partners, and the project team have signed a Memorandum of Understanding with the Queensland Government-owned CS Energy.

The scope of works includes: 

  • two reservoirs: the upper being a valley fill reservoir and the lower being an in-stream reservoir in the Broken River
  • a powerhouse
  • tunnels or pipes linking the reservoirs and the powerhouse, and
  • a transmission line and substation.
