Koolunga Battery Energy Storage System

Equis is developing a 200MW battery near Koolunga to help provide South Australia with reliable energy
Koolunga, South Australia

About the project

The proposed Koolunga Battery Energy Storage System (BESS) is located approximately 1.1km northeast of the Brinkworth Substation on Power Station Road. The BESS has a battery energy storage capacity up to 200MW and discharge capacity up to 800MWh, which is enough power to supply electricity for up to 380,000 homes for four hours.

The BESS site will be connected to South Australia’s electricity grid via a transmission line that connects to the 275kV Brinkworth Substation. The project will help to secure South Australia’s future electricity demands.

The BESS will provide significant local benefits during construction and operation with investment in the local economy. The BESS will create approximately 110 full times jobs during construction and 5 during operations as well as funding community programs.

Planning and Environment Approvals

Equis has engaged specialist consultants to assess potential environmental impacts and engage with the local community.

Equis has now submitted the development application for the Project to the State Planning Commission for consideration. The State Planning Commission is the relevant authority for the assessment of this application as the proposed development involves an electricity generating plant with a generating capacity of 5 MW or above connected to the State’s power system.

The Project has been granted development approval on the 10th August 2023.

Update: Community Drop-in Session

Equis completed its first community drop-in session on the 29th of March at Brinkworth Recreation Ground Club Rooms between 3pm and 7pm. For further information please click the link below.
