Oven Mountain Pumped Hydro Project: Home

The Oven Mountain Pumped Hydro Project pays its respect to the Traditional Custodians of Country, their Elders—past and present, and acknowledges their ancestral connection to the land, seas, and waterways. The project honours the collective knowledge, experiences, cultures, and traditions of all Aboriginal and Torres Strait Islander peoples who for thousands of years have shared and exchanged knowledge, nurtured, and loved Country for the benefit of all.

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.

It will work like a big battery, storing energy by pumping water more than 600 metres uphill from one reservoir to another.

When required, water will be quickly released and run through the turbines to produce electricity.

At 900 MW for 8 hours, the project would generate up to 7,200 MWh (7.2 GWh) which could power over 600,000 homes.

Advanced stage of development

The project is at an advanced stage of development and we aim to commence construction in 2026, pending final planning approval from state and Commonwealth governments.
