Western Australia’s state-owned coal power stations will be retired by 2030 as the continued uptake of rooftop solar and renewables forces changes in the energy system to ensure a secure electricity supply and guard against higher power bills.

Collie Power Station will close in late-2027 and Muja D in late-2029. As previously announced, Muja C’s Unit 5 will close later this year and Unit 6 in 2024.

An estimated $3.8 billion will be invested in new green power infrastructure in the South West Interconnected System (SWIS)—including wind generation and storage—to ensure continued supply stability and affordability.

The investment in new renewable power infrastructure is expected to pay for itself by 2030-31 relative to the increasing electricity subsidies payable under the status quo.

A new $547.4 million Collie Transition Package will support the town of Collie over the next decade, to grow new industries and local jobs—bringing the government’s investment in the area to over $662 million.

The Collie Transition Package includes a new $200 million Collie Industrial Transition Fund, expanded skills and training opportunities for workers and additional job-creating investment.

The state government has also committed to not commissioning any new natural gas-fired power stations on the SWIS after 2030.

Energy Minister Bill Johnston said, “The amount of rooftop solar coming online currently in WA is roughly the equivalent of adding a new coal-fired generation unit every year. This is putting unprecedented pressure on the system and we must act to keep costs as low as possible, while transitioning to higher levels of renewables and storage.

“Our new investment in the South West Interconnected System represents an extraordinary investment in the future of our electricity system, including a massive reduction of Synergy’s carbon emissions.

“We will be working closely with impacted businesses, workers and communities to ensure we create new jobs and training opportunities to future proof Collie for the coming decades.”
