The Longyear coal-fired power station is the only coal-fired power station in Norway and is the world's northernmost coal-fired power station in Longyearbyen on the Spitzbergen archipelago . The power plant, built in 1983, is designed as a combined heat and power plant with an installed capacity of 28 MW and provides a maximum of 12 MW of electrical energy and 16 MW of district heating for the town of Longyearbyen surrounding the power plant.
The coal required to operate the power plant is obtained from Mine 7 at Store Norske Spitsbergen Kulkompani . Approx. 25,000 tons of hard coal are burned in the coal-fired power plant per year , which corresponds to about a third to half of the amount of coal extracted from Mine 7. In addition to the village of Longyearbyen, the coal-fired power station also supplies all surrounding facilities such as the coal mine and Longyearbyen Airport . Due to its isolated location, the electrical power grid in Spitzbergen is designed as a so-called island grid and has no external connection. Since there is no external power supply in the event of a fault in the power plant, three diesel-operated emergency power generators with 2 MW each are also available in the stand-alone grid .
The power plant consists of two separate boilers for burning the coal. In addition, a heating oil boiler can be switched on to generate district heating in extremely cold weather. Two steam turbines and two electric generators with 7 MW each are available for generating electrical energy . The power grid in Longyearbyen is designed as a medium-voltage network due to its comparatively small size and is operated with a nominal voltage of 10.6 kV .
