Longannet power station used water drawn from the Firth of Forth, the estuary (firth) of several Scottish rivers including the River Forth, for the station's cooling condensers circulated by four electrically driven pumps.
The station stands on the north bank of the Firth of Forth, near Kincardine on Forth. The chimney is 183 metres (600 ft) tall; the station did not have cooling towers, instead using water drawn from the Firth of Forth at a rate of 327,000 cubic metres (11,500,000 cu ft) per hour for the station's cooling condensers. Longannet lacked cooling towers, having instead used water from the River Forth for cooling. The water was passed through coarse screens and then circulated by four electrically driven pumps. Once circulated through the station's condensers, the water was discharged into a mile long cooling channel, where heat was dissipated before the water reached a wide part of the Forth.
