Perth-headquartered renewable energy developer BLT Energy secured development approval for its Red Gully 800 MW / 4,800 MWh battery energy storage system (BESS) in Western Australia. The project, located adjacent to state-owned utility Western Power’s Regans Terminal, will be the largest utility-scale BESS proposed in WA upon completion. Phase 1 of the project will deliver 400 MW of power with 2,400 MWh of storage to the South West Interconnected System (SWIS), with full completion targeted for 2027. The Red Gully BESS complements WA’s Clean Energy Link – North transmission network upgrade program, reinforcing grid stability amid the state’s renewable energy expansion. Western Power’s involvement underscores the collaborative effort to integrate large-scale storage into the regional grid infrastructure.
