BLT Energy Bags Development Approval for 4.8GWh Red Gully BESS in Western Australia

Why It Matters

Red Gully will be the largest battery storage proposal in WA, bolstering grid reliability as coal plants close and accelerating the state’s renewable transition. Its scale also supports the Capacity Investment Scheme’s goal of delivering gigawatts of clean‑energy infrastructure and jobs.

Key Takeaways

• Red Gully BESS approved for 800 MW, 4,800 MWh capacity
• Phase 1 will deliver 400 MW and 2,400 MWh to SWIS
• Commissioning slated for 2028‑2029, ahead of 2030 coal retirements
• Project will become WA’s largest battery storage proposal upon completion

Pulse Analysis

Western Australia’s isolated grid has become a global showcase for battery‑storage penetration, with utility‑scale systems supplying over a third of peak demand in 2026. This rapid uptake is driven by aggressive state policies, the Capacity Investment Scheme, and a clear timeline to retire coal‑fired generators by 2030. The success of projects like Synergy’s 500 MW Collie BESS has demonstrated the technical and economic viability of large‑scale lithium‑iron‑phosphate containers, encouraging further private investment.

The Red Gully BESS, now cleared by the Regional Development Assessment Panel, will be built in two phases adjacent to Western Power’s Regans Terminal. Phase 1’s 400 MW/2,400 MWh capacity will feed the South West Interconnected System, providing fast‑response reserves and firming renewable output. BLT Energy’s next steps include detailed engineering, financing, and community‑benefit negotiations with the Shire of Gingin and Traditional Owners, ensuring local support while positioning the site as a cornerstone of the Clean Energy Link‑North transmission upgrade.

Beyond regional reliability, Red Gully’s approval signals a broader market shift. The project’s $5 billion (US$3.51 billion) CIS‑backed pipeline promises thousands of construction jobs and reinforces Australia’s ambition to lead in utility‑scale storage. As the largest battery proposal to clear WA’s approval process, Red Gully will set new benchmarks for capacity, technology integration, and project delivery, influencing future storage bids and accelerating the nation’s transition to a low‑carbon electricity system.
