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 an approval to store up to 300MW, which is enough power to supply electricity for up to 20,000 homes for two 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 and will provide significant local benefits during construction and operation including investment in the local economy. The BESS will create approximately 170 full time jobs during construction and 7 during operations as well as funding community programs.
We welcome and invite local and regional partnering opportunities. You can register your interest on the provider/supplier registration form in the forms and surveys section below.

Construction and Traffic Updates
Variation to Construction Hours
Equis is consulting nearby residents on a proposed variation to the construction hours for the Calala Battery Energy Storage System (BESS). The variation is required to support more efficient sequencing of construction activities and help minimise the overall construction timeline.
Proposed Work Hours (Monday–Sunday):
- 6:30am – 7:00am: Low‑noise activities
- 7:00am – 5:00pm: General construction works
- 5:00pm – 5:30pm: Low‑noise activities
