In June 2022, the Government of Western Australia announced that Synergy would close Collie Power Station by 2027.{{cite news |title=Synergy coal power stations including Muja to close as WA Government prioritises renewable energy |first=Daniel |last=Mercer |date=2022-06-14 |work=ABC News|publisher=Australian Broadcasting Corporation |url=https://www.abc.net.au/news/2022-06-14/muja-power-station-to-close-in-coal-phase-out-as-renewables-rise/101150972 |access-date=2022-06-14}}

Built by the Clough Group, the station was commissioned in 1999 with a single 300 megawatts steam turbine.[http://web.archive.org/web/20221209220542/https://cloughgroup.com/projects/new-collie-power-station New Collie Power Station] Clough Group{{cite web

In the financial year of 2008/2009, the station consumed approximately {{convert|1|e6t|e9lb|abbr=off}} of coal. Carbon Monitoring for Action estimates that, in 2009, Collie Power Station emitted {{convert|{{#expr: (2592300 / 10^6 ) round 2 }}|e6t|e9lb|abbr=off}} of {{CO2}} to generate {{convert|{{#expr: ( 2299700 / 10^6 ) round 2 }}|TWh|PJ|abbr=off}} of electricity.{{cite web|url=http://carma.org/plant/detail/9063|date=July 2012

In household consumer terms, this equates to {{convert|1.13|kg}} of {{CO2}} emitted for each one kilowatt-hour (kWh), or {{convert|1|kWh|MJ|abbr=off|disp=out}}, of electricity produced and fed into the electricity grid. That is, Collie Power Station emits slightly less {{CO2}} per kilowatt-hour of electricity produced than nearby closing Muja Power Station ({{convert|1.14|kg|lb|disp=or}}) but more than also nearby Bluewaters Power Station ({{convert|0.825|kg|lb|disp=or}}) based on estimates for the same year.

Two grid batteries are being built at the site; a 219 MW / 877 MWh (4-hour) to reduce the solar duck curve,{{cite web |title=First stage of Australia’s biggest battery project energised to start flattening solar duck |url=https://reneweconomy.com.au/first-stage-of-australias-biggest-battery-project-energised-to-start-flattening-solar-duck/ |website=RenewEconomy |language=en-AU |date=15 July 2024}} and a 500 MW / 2000 MWh (4-hour).{{cite web |title=Construction starts on Australia’s biggest battery, to replace Collie coal |url=https://reneweconomy.com.au/construction-starts-on-australias-biggest-battery-to-replace-collie-coal/ |website=RenewEconomy |language=en-AU |date=15 March 2024}}
