Ausgrid Submits 300MWh Berkeley Vale BESS in New South Wales to Australia’s EPBC Act

Why It Matters

The BESS will bolster New South Wales’ ability to meet its 56 GWh storage goal by 2030, enhancing grid reliability and supporting the renewable transition. Its approval also signals regulatory momentum for similar utility‑partnered storage projects nationwide.

Key Takeaways

• Ausgrid's 150 MW/300 MWh Berkeley Vale BESS submitted for EPBC review
• Project will clear 1.55 ha of native vegetation on a 2.25 ha site
• NSW storage target rises to 56 GWh by 2030, creating pipeline demand
• Third‑party operators will build and run the battery on Ausgrid’s network
• Similar 200 MW/400 MWh projects already approved despite public objections

Pulse Analysis

New South Wales has accelerated its battery‑storage agenda in response to a widening gap between the state’s 2030 target of 56 GWh and the capacity already contracted. The target, up 40 % from the mid‑2025 projection, is driven by the need to smooth intermittent renewable generation and to provide firm capacity for the National Electricity Market. Recent approvals, such as the 200 MW/400 MWh Steel River East project, illustrate a regulatory willingness to clear large‑scale storage despite community push‑back, signaling a robust pipeline of similar developments.

Ausgrid’s latest submission, the 150 MW/300 MWh Berkeley Vale Battery Energy Storage System, seeks federal clearance under the EPBC Act. Sited on a 2.25‑hectare parcel adjacent to the existing Berkeley Vale zone substation, the facility will use containerised battery modules, a 33 kV underground cable, and ancillary infrastructure such as fire‑suppression and a backup diesel generator. By storing grid electricity and dispatching it during peak demand, the BESS will deliver ancillary services to the NEM while clearing 1.55 ha of native vegetation, a trade‑off that the EPBC review will evaluate.

The project follows Ausgrid’s emerging model of partnering with third‑party investors who finance, construct, and operate the storage assets on the network operator’s behalf. This approach reduces capital exposure for utilities while expanding the market for private storage developers. As more EPBC referrals accumulate, the competitive landscape is likely to tighten, prompting faster cost reductions and encouraging integration of longer‑duration storage to meet the state’s ambitious targets.
