Armidale BESS
150MW/300MWh utility-scale battery energy storage system project.

Scheduled for completion in 2023, Armidale BESS is a utility-scale battery located approximately 5km East of Armidale, NSW.

Our commitment to a brighter future.

The battery system will store approximately 300MWh of electricity, which will power more than 20,000 homes.

Armidale BESS will involve the development of a utility-scale battery energy storage system 5km E of Armidale in New South Wales; the Armidale BESS will have a capacity of 150MW which will connect into the Armidale 330kV transmission substation. The project will be completed in one stage.

The Armidale BESS would provide the following benefits, specific to Australia’s commitments

Reduction in greenhouse gas emissions required to meet our clean energy transition

Additionally, the proposal would allow for the:

  • Provision of embedded electricity generation, to supply into the Australian grid closer to the main consumption centres
  • Provision of social and economic benefits, through the provision of direct and indirect employment opportunities during construction and operation of the project

The Armidale BESS site is located around 360km from both Brisbane and Sydney load centres. The project location is within the Armidale Regional Council Local Government Area (LGA). The site is located off Waterfall Way, on Eathorpe Road and is situated directly adjacent to the Armidale 330kV transmission substation.


The Armidale BESS site consists of private freehold land on which approximately 2.1 hectares of land will be used for the BESS units and an additional 0.5 hectare will be used to house operational and maintenance equipment.

The preliminary layout provides for a 150MW/300MWh BESS; the capacity of the project is based on the available capacity at the Armidale 330kV transmission substation that the project will connect to. The project is a standalone BESS which will charge and discharge from the National Electricity Market and will NOT have a generation component like a solar or wind farm.


Given the capital cost of the project, its development application will be assessed by the NSW Department of Planning, Industry & Environment (DPIE).

In this context, a Scoping Report for the Armidale BESS has been lodged with DPIE in June 2021.

Once the Scoping Report is assessed, DPIE will issue SEARs which will outline the requirements for an Environmental Impact Assessment.

Studies undertaken will include:

  • Heritage (including Aboriginal heritage);
  • Visual amenity;
  • Noise assessment;
  • Hazard assessment;
  • Soils and water;
  • Traffic assessment;
