The Oven Mountain Pumped Hydro Energy Storage project is a proposed 600 megawatt 'off river' facility located on private land near the Macleay River between Armidale and Kempsey in the New England region of NSW.
The project is being overseen by Oven Mountain Pumped Storage (OMPS) who have partnered with Alinta Energy to co-develop the project. It is located within the New England Renewable Energy Zone.
The facility is expected to provide up to 12 hours of storage capacity. The project will include the construction of two reservoirs, tunnels and a new underground power station. As part of the project, upgrades to up to 60 kilometres of existing roads between Armidale and Kempsey will be required to allow for safe construction and operation access.
