EnergyAustralia is currently investigating the feasibility of a pumped hydro energy storage project on land and waterways it owns near Lithgow, in NSW, with technical and environmental studies underway.
If the project progresses, we expect roughly 2 years for its design and development and then 3 to 4 years for its construction, meaning 2029 would be the earliest we could see the Lake Lyell Pumped Hydro Project facility in full operation.
In July 2024, the NSW Government declared the Lake Lyell Pumped Hydro project as Critical State Significant Infrastructure (CSSI). This highlights its importance as essential, high-priority infrastructure for the state. More information on this planning approval pathway can be found on the NSW Department of Planning, Housing, and Infrastructure’s website.
Despite its CSSI status, the project will still undergo extensive investigative work and technical studies. We will continue to release more information as we complete the project’s Environmental Impact Statement (EIS). We’re also committed to working closely with the Lithgow community, including Traditional Owners, to ensure the project’s successful development and to maximise its benefits for Lithgow.
Below is the current outline of the project’s potential timings, which are subject to movement.
Over the coming 18 months, we look to create many opportunities for the local community, Traditional Owners, and any interested stakeholders to engage with us about the project, so we can hear your views, and receive your feedback.
Technical and environmental studies have begun for the proposed Lake Lyell Pumped Hydro Project.
These studies will form the project’s Environmental Impact Statement (EIS) and follow the release in August 2023 of the NSW Government’s Secretary’s Environmental Assessment Requirements (SEARs). SEARs details the things that must be included in the EIS.
Over the next 12 months, experts will look at the potential impacts of the project along with mitigation measures. They will analyse biodiversity, aquatic ecology, Aboriginal heritage, social impact, water and climate effects, and more.
Community engagement will continue to be an essential part of the project and EnergyAustralia will share the EIS, which is expected to be ready in mid-2024, and seek community input.
After completion, the Lake Lyell Pumped Hydro Project would operate for up to 80 years, generating 335 MW of clean energy for 8 hours at a time – offering reliable and affordable energy to support homes and business in the Central West region and across the state, whilst playing a vital and integral part in Australia’s clean energy transformation.
Through the project’s development and design, EnergyAustralia is committed to maintaining regular consultation with the local community to creating a range of new community benefits, and ensuring Lake Lyell can be maintained as an area for recreation.
