Project Description

The proposed Borumba Pumped Hydro Project is a 2,000 MW pumped hydro energy storage system at Lake Borumba, located near Imbil, west of the Sunshine Coast.

Pumped hydro allows for renewable energy to be stored and dispatched at times when the sun isn’t shining and the wind isn’t blowing.

Early exploratory works at the project site involve drilling of a D-shaped shaft along one of the proposed access tunnels and excavating soil and rock. Exploratory works will also include surface based geotechnical drilling, including near the existing Borumba Dam wall.

The existing Lake Borumba lower reservoir will be expanded with a new dam wall downstream from the current Borumba Dam, with a second reservoir will be constructed at a higher altitude. An underground powerhouse will link the two reservoirs together. When electricity is required, water will be released from the upper reservoir through underground turbines via tunnels to the lower reservoir.
