Calala Battery Energy Storage System

Equis is developing a 300MW battery near Tamworth to help provide New South Wales with reliable energy
Calala, New South Wales

About the project

The proposed Calala Battery Energy Storage System (BESS) is located approximately 5.8km southeast of the Tamworth CBD within the Tamworth regional municipality. The BESS has a battery energy storage capacity of up to 300MW and discharge capacity up to 1,200MWh, which is enough power to supply electricity for up to 570,000 homes for four hours.

The BESS site will be connected to NSW’s electricity grid via a transmission line that connects to the 330kV Tamworth Substation. The project will help meet NSW’s future electricity demands.

The BESS will provide significant local benefits during construction and operation including investment in the local economy. The BESS will create approximately 170 full times jobs during construction and 7 during operations as well as funding community programs.
