Background on Plant

The Millmerran Power Station is an 880 MW coal-fired power station near the town of Millmerran on the Darling Downs in southern Queensland. The plant is an air-cooled supercitical design which the company states uses 10% less coal and 90% less water than conventional coal plants.[1]

Intergen states that the Millmerran Operating Company "employs 50 people directly and 150 people indirectly when coal mine employees and other sub-contractors are included." Coal for the power station is sourced from the adjacent Commodore mine. InterGen is owned jointly by the Ontario Teachers' Pension Plan and China Huaneng Group/Guandong Yudean Group.[1]

In June 2015, the Millmerran power station was refinanced to cover existing indebtedness. US$597.51 million in debt was provided by a consortium of banks, and US$597.51 million in equity was provided by InterGen, Marubeni, Tohoku Electric Power, and GE Capital.[2]

Environmental impact

National Pollutant Inventory (NPI) data for 2016-2017 show that Millmerran emitted the most mercury of any power station outside Victoria, with 256.4 kg.[3][4]

In November 2019 the plant was chosen by the Australia Coal Association's Coal21 fund as the site of a planned integrated carbon capture, utilisation and storage (CCUS) project. The project would cost an estimated A$150 million.[5]
