Big-T Pumped Hydropower Energy Storage project - draft terms of reference for an environmental impact statement

Closed 22 Feb 2023

Opened 21 Jan 2023


Queensland's Coordinator-General invites you to have your say on the draft terms of reference (TOR) for an environmental impact statement (EIS) for the Big-T Pumped Hydropower Energy Storage project. 

The draft TOR sets out the matters to be studied within the EIS. You are invited to comment on whether the draft TOR adequately covers all the matters the proponent BE Power Projects Pty Ltd must address when preparing the EIS.

About the project

The proponent, BE Power Projects Pty Ltd as Trustee for Big-T Unit Trust, proposes to develop the $1.3 billion Big-T Pumped Hydropower Energy Storage project. The project involves development of a pumped hydropower energy storage project in the Southern Queensland renewable energy zone with the capacity to generate up to 400 megawatts (MW) of continuous electricity for 10 hours per day, and a battery energy storage system with a capacity of 200 megawatt hours (MWh). The proposed project is located approximately 45 kilometres (km) north-east of Toowoomba, Queensland, in the Toowoomba Regional Council and Somerset Regional Council local government areas.

The Coordinator-General declared the project a ‘coordinated project’, under section 26(1)(a) of the State Development and Public Works Organisation Act 1971 (SDPWO Act) (Qld), triggering the requirement for an EIS.

On 22 March 2022, the delegate for the former Minister for the Environment determined the project to be a ‘controlled action’ under section 75 of the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) (EPBC 2021/9140), as the project has the potential to impact on matters of national environmental significance (MNES). The controlling provision is listed threatened species and communities (sections 18 and 18A). The project will be assessed under a bilateral agreement between the Australian and Queensland governments (section 45 of the EPBC Act). The Coordinator-General’s EIS evaluation report will be provided to the Minister.
