Karangi

Avenis Energy is proposing to construct and operate a Battery Energy Storage System (BESS) in Karangi, NSW.

Avenis Energy is proposing to develop the Karangi Battery Energy Storage System (BESS), a utility-scale battery project approximately 11 km northwest of Coffs Harbour in Karangi, NSW, adjacent to the existing Coffs Harbour Transgrid 330 kV substation.

The Project is proposed to have an indicative capacity of 240 MW / 960 MWh, meaning it could store and dispatch electricity for up to four hours at full capacity. A BESS does not generate electricity itself. It stores electricity from the grid when there is available supply and releases it when the grid requires support, including during periods of higher demand or lower generation.

The Project is still in the assessment and design-refinement stage. Detailed technical studies and community feedback through the Environmental Impact Statement (EIS) process will inform the final layout, access arrangements, visual screening, noise controls, traffic management, water management, bushfire and fire safety measures, and other mitigation requirements before any construction could occur.

The Karangi BESS would include the following key components:

• Containerised Battery units

• Power Conversion Units (Inverter stations)

• Transformers

• An onsite 330 kV substation and supporting electrical equipment

• Underground or overhead electrical connection infrastructure

• Internal access roads

• Switch yard

• On-site water storage

• Fire suppressions systems

• Security fencing

• Parking site

• Site office and amenities for operational use

• Landscaping and vegetation screening

During construction, temporary infrastructure including construction facilities, site offices and amenities, tool and material storage sheds, construction staff car parking, component laydown areas and truck parking and unloading would also be required and commercial opportunities around Coffs Harbour.

The final equipment, layout and construction approach will be confirmed through detailed design, technical assessments, consultation and the planning approval process.
