Specifics of assessing energy security of isolated energy service areas in territories with harsh climatic conditions

The specifics of regional energy economies support the need in excellent methodical approaches to diagnosing energy security of territorial formations, in general, and by internal components even on the same level. This emphasises the relevance of refining and establishing top priorities for energy security state assessment indicators for isolated territories with long low-temperature periods. Such territories include a part of the territory of the Russian Federation located mainly to the north of the Arctic Circle. The climate is extremely harsh, it is an arctic area. One can name Canada, Sweden and Finland, the USA, Iceland, Denmark and Alaska among such countries. We make an attempt of drawing an actual picture of territorial conditions and existing situations based on apparent factors in distinct directions of the formulated definition of energy security of decentralised energy supply areas.
