What’s the project’s current status?

The Oven Mountain Pumped Hydro Project is currently in the advanced development stage.

It will bring much-needed, long-duration storage and reliability to the National Electricity Market, generating up to 900 MW of electricity and storing enough water for up to eight hours of dispatchable energy at full generation for 100+ years.  At 900 MW for 8 hours, the project would generate up to 7.2 GWh which is enough to power over 600,000 homes.

Pumping and releasing water between two reservoirs on private land (away from the Macleay River) means there’s no need to dam the Macleay River for the project, and it won’t have a net impact on local water use.

It will also result in many market and environmental benefits, including an annual reduction of approximately 400,000 tonnes of CO2-e in generation emissions.

It will take approximately five years to construct and we’re aiming for it to commence operating in the early 2030s.

Community and benefit sharing

This project is expected to inject more than $40 million into the regional economy, employ up to 800 people during construction, and generate up to 95 direct and indirect jobs once operational. It’ll also deliver improvements to local roads and provide an emergency water supply for bushfire fighting. And we’ll establish a regional benefit sharing scheme for the project, which will be designed with the community. 

 

Project elements

Construction or upgrades needed, if the project is approved:

  • upper and lower reservoirs
  • an underground hydroelectric power station
  • spillways
  • power waterway
  • access tunnels
  • telecommunication services and local and regional roads
  • a transmission line upgrade back to Armidale
  • a new 15km transmission line to connect to the electricity grid
