Lower Wonga Battery Energy Storage System

Equis is developing a 200MW battery near Lower Wonga (Woolooga) to help provide Queensland with reliable energy.
Lower Wonga (Woolooga), Queensland

About the project

The proposed Lower Wonga (Woolooga) Battery Energy Storage System (BESS) is located approximately 0.8km southwest of the Woolooga Substation on Gympie Woolooga 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 Queensland’s electricity grid via a transmission line that is connects to the 275kV Woolooga Substation. The project will help to secure Queensland’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 110 full times jobs during construction and 5 during operations as well as funding community programs.
