It will work like a big battery, storing energy by pumping water more than 600 metres uphill from one reservoir to another.
Oven Mountain Pumped Hydro, a critical project for the NSW energy transition
The 900 MW 8-hour pumped hydro project will help NSW replace coal-fired power and support the addition of more renewables to our energy system.
It’ll be a big water-powered battery with big benefits, including a $40 million economic boost for the region, and will support the creation of hundreds of jobs.
When required, water will be quickly released and run through the turbines to produce electricity.
At full capacity (900 MW for 8 hours), it would provide reliable energy to over 600,000 homes.
Advanced stage of development
The project is at an advanced stage of development and we aim to commence construction around mid-2025, pending final planning approval from state and Commonwealth governments.
