It is also the second tallest freestanding structure of any type in Canada, behind the CN Tower but ahead of First Canadian Place. It is the 51st tallest freestanding structure in the world. The Superstack is located on top of the largest nickel smelting operation in the world at Vale's Copper Cliff processing facility in the city of Greater Sudbury.
Schilling Power Station was an oil-fired power station in the proximity of the nuclear power station at Stade. It went into operation in 1960, was extended in 1962 and 1964, and was shut down in the 1980s. Since it principally served Hamburg north for the electricity supply of Hamburg and fed its current into the transformer station, the first overhead line crossing of the Elbe was built at that time at Stade, the Elbe Crossing 1. The buildings still exist today and are occasionally used for disaster control exercises.

The flue gas stack of Teruel Power Plant is 343 metres (1,125 ft) high. Lignite room is developed, and contained up to 7% sulphurs. Teruel Power Plant has three generating units with a capacity of 350 megawatts each. In 1992, Teruel Power Plant was equipped with filters, so now more than 90% of the detrimental sulfur dioxide are filtered out from smoke. The plant was closed in 2020.
