EnergyAustralia today released the Concept Design for its proposed Lake Lyell Pumped Hydro Project providing details on key project elements including the upper reservoir design, site access roads, underground powerhouse, the switchyard and water intake location.
This milestone demonstrates EnergyAustralia’s commitment to progressing projects that are vital in the transition of the electricity system away from coal and towards renewables.
Michael de Vink, EnergyAustralia Lake Lyell Pumped Hydro Project Director said: “The Concept Design emphasises our commitment to mitigating environmental, cultural heritage and other important impacts through site-sensitive design. This includes changes made following consultation with the community and initial environmental studies.
“The siting of key elements of the project takes advantage of the natural geography of the site to avoid visual impacts, mitigate environmental impacts and maintain lake recreational access for the community.
“The Concept Design allows us to plan further studies to assess the project’s environmental impact and supports our progress with more detailed engineering design work.
“It will also be a key feature of our ongoing community consultation program and provides additional detail to allow us to continue working with the Lithgow community. This includes opening a new community information centre on Main Street, Lithgow today.”

Mr de Vink added: “Our engagement with the Lithgow community has provided invaluable information and feedback to the project, and the Plan released today provides additional detail to allow us to continue to consult and collaborate with them to optimise Project elements and ensure that adverse impacts are minimised.
“We are continuing to develop a road map for benefit-sharing to identify investments that can return meaningful benefits to the community, delivering on our commitment to build social licence and the future economic prosperity of the region.
“The next step for the project is more detailed assessments and continuing community engagement. For example, environmental studies are currently underway with findings to be included in the Project’s Environmental Impact Assessment which is expected to be on public exhibition towards the end of next year.
“We are using experienced specialists to inform the design and assess the impacts of the project. For example, the University of NSW has been providing advice on measures to conserve populations of platypus.”
Modifications to the Concept Design may be made to address environmental impacts identified during the environmental assessment program and in response to community feedback.
Details of the Concept Design are available on lakelyellpumpedhydro.com.au including a new visualisation of the project based on the Concept Design.
The Lake Lyell Pumped Hydro project is in the feasibility stage with a decision on proceeding likely in the second half of 2025. Construction would take at least four years. The 335MW project would provide energy for 150,000 homes for up to eight hours.
