The Commodore mine is an open cut thermal mine in Queensland, Australia.

The mine supplies coal to the Millmerran power station, an 850 megawatt coal-fired power station owned by Intergen. The power station is located near the town of Millmerran on the Darling Downs in southern Queensland.[5] . The mine is operated by Downer EDI and will likely operate through August 2024.[6]

It is unclear when mining at Commodore mine (also known as Millmerran) officially began. MiningLink reports that at the beginning of 1991, the Commodore coal mine was mining 3.25 million tonnes of coal per year.[7] According to Queensland Coal: Physical and Chemical Properties, Colliery and Company Information, published in 2003, “construction of the mine commenced in May 2001, and coal supply to the 840MW Millmerran power station commenced in 2002.”[8]

Commodore is the only coal provider for the Milmerran power station. The Commodore coal reserves are estimated to be sufficient to fuel the plant for at least 50 years of operation.[8] Also notable is that Commodore mine was the first open pit coal mine in the world to dedicate itself to using entirely biodiesel fuel.[7]

In September 2018, Downer EDI received a contract extension from the Milmerran Power Partners to continue mining for five more years, until August 2024.[6]
