Bunnerong Power Station: Bunnerong Power Station is a demolished former coal-powered electric power station in the south-eastern Sydney suburb of Matraville, New South Wales, Australia.  When the last generating units were commissioned, it was the largest power station in the southern hemisphere, with a capacity of 375 megawatts (MW) from eleven turbo-alternators.  It was able to supply up to one third of the state's electricity needs at the time.  It remained the most powerful until the completion of Vales Point Power Station in 1966.

Eraring Power Station: Eraring Power Station is a coal fired electricity power station with four 720 MW Toshiba steam driven turbo-alternators for a combined capacity of 2,880 MW.  The station is located near the township of Dora Creek, on the western shore of Lake Macquarie, New South Wales, Australia and is owned and operated by Origin Energy.  It is Australia's largest power station.

Lough Ree Power Station: The Lough Ree Power Station is a large peat-fired power station in Lanesborough, in the Republic of Ireland.  The station generates up 100 MWe of power, ranking as the Third largest peat-fired power station in the country, after West Offaly Power Station at 150 MWe .  and Edenderry Power Station at 120 MWe .  The power station was constructed as a replacement to the ageing 85 MWe Lanesborough power station.

Manapouri Power Station: Manapouri Power Station is an underground hydroelectric power station on the western arm of Lake Manapouri in Fiordland National Park, in the South Island of New Zealand.  At 850 MW installed capacity (although limited to 800 MW due to resource consent limits), it is the largest hydroelectric power station in New Zealand, and the second largest power station in New Zealand.  The station is noted for the controversy and environmental protests by the Save Manapouri Campaign against the raising the level of Lake Manapouri to increase the station's head, which galvanised New Zealanders and were one of the foundations of the New Zealand environmental movement.

Conveyor belt: A conveyor belt is the carrying medium of a belt conveyor system (often shortened to belt conveyor).  A belt conveyor system is one of many types of conveyor systems.  A belt conveyor system consists of two or more pulleys (sometimes referred to as drums), with an endless loop of carrying medium—the conveyor belt—that rotates about them.  One or both of the pulleys are powered, moving the belt and the material on the belt forward.  The powered pulley is called the drive pulley while the unpowered pulley is called the idler pulley.  There are two main industrial classes of belt conveyors; Those in general material handling such as those moving boxes along inside a factory and bulk material handling such as those used to transport large volumes of resources and agricultural materials, such as grain, salt, coal, ore, sand, overburden and more.

Pembroke Power Station: Pembroke B Power Station is a 2,000 MWe natural gas-fired power station near Pembroke in Wales.  The power station was officially opened on 19 September 2012 and is the largest gas-fired power station in Europe.  It is also the largest power station to be built in the UK since Drax power station came online in 1986.  Pembroke Power Station currently generates enough power to supply 3.5 million homes and businesses.

Chain Valley Colliery: Chain Valley Colliery is a coal mine located at Mannering Park, New South Wales, Australia.  The colliery was developed to provide coal for the Vales Point Power Station, adjacent to the mine.  The mine started in August 1960, with coal production commencing in 1961.  The Great Northern and Fassifern coal seams have been mined using bord and pillar mining methods.  Coal is transported to the Vales Power Station by an overland conveyor system, while excess coal is trucked to domestic customers and also to the Port of Newcastle for export.

Ryazan Power Station: The Ryazan Power Station (also called Novomichurinsk Power Station) is the fifth largest oil-fired power station in the world, also the fifth largest power station in Russia, with an installed capacity of 3,130 MW.  The power station is located in Novomichurinsk of the Ryazan Oblast, Russia.  Construction began in 1968 with the first unit going online in 1973.

Myuna Colliery: Myuna Colliery is a coal mine at Wangi Wangi, New South Wales, Australia.  The colliery was developed to provide coal for the Eraring Power Station, 5 kilometres to the west.  The mine started in August 1979, with coal production commencing in 1982.  The Wallarah, Great Northern and Fassifern coal seams have been mined using bord and pillar mining methods.  Coal is transported to the Eraring Power Station by an overland conveyor system.

Collie Power Station: Collie Power Station is a power station in Collie, Western Australia.  It is coal powered with one steam turbine that generates a total capacity of 300 MW of electricity.  The coal is mined locally from the Collie Sub-basin and is transported to the power plant by overland conveyor.
