(NSE) OVEN MOUNTAIN PUMPED HYDRO

The Oven Mountain Pumped Hydro Storage Project is an off-river development in New South Wales, Australia. The project is owned and will be developed by Alinta Energy.

With an estimated base cost of approximately A$1.97bn ($1.29bn), the construction of the project will commence at the end of 2024 creating 600 jobs during construction.

The targeted year for the commencement of commercial operations is 2029. Oven Mountain will have an operational life of over 100 years.

Once operational, the off-river development will produce up to 900MW of renewable electricity and between eight to 12 hours of dispatchable energy for storage and distribution to the National Electricity Market.

Oven Mountain Location Details

The Oven Mountain Pumped Hydro Storage Project will be located approximately 60km southeast of Armidale and 70km northwest of Kempsey through the Kempsey-Armidale Road on private land.

The project will be situated at the southeastern corner of the Armidale Regional Local Government Area (LGA) close to the Kempsey Shire LGA within the New England Regional Economic Zone (REZ). The project will be developed within Australia’s Thunggutti Aboriginal Community area. The Macleay River borders the project from the west and the Carrai Tablelands surround the project from the east.

Oven Mountain Key Infrastructure

The Oven Mountain Pumped Hydro Storage Project will consist of an underground power station, dams and reservoirs, water intake structures, spillways, a Macleay River pump facility, tunnels, and a power waterway.

The project will have two concrete-faced rockfill dams with an upper and a lower reservoir. The upper dam and reservoir will be approximately 780m long and 70m high. The upper reservoir will cover approximately 20 hectares (ha) area with an inundation extent of approximately 16.7ha.

At the Full Supply Level (FSL), the upper reservoir will have a storage capacity of around 5.1 gigalitres (GL) and a height of approximately 881mAHD. More of this article (NS Energy) - link - more like this (hydro) - link - more like this (Australia) - link
