Queensland Hydro is a publicly owned entity established by the Queensland Government to design, deliver, operate, and maintain long duration pumped hydro energy storage assets that will be the cornerstone for the transformation of the state’s energy system. This transformed energy system will predominantly rely on wind and solar energy generation, complimented by dispatchable energy sources such as batteries and pumped hydropower energy storage (PHES). Long duration PHES will be a critical component of this future energy mix.

The objective of this Expression of Interest (EOI) is to shortlist suitable underground tunneling and drilling works Contractors to participate in the Request for Proposal (RFP) for the Underground Tunneling and Drilling Works for the Borumba PHES Exploratory Works.

For detailed information on the specific services sought, please refer to the Scope of Works document within Volume 3 of this EOI.
