A Comprehensive Evaluation Method the Effectiveness of the Prospect of Inter-Fuel Competition for the Production of Electric and Thermal Energy in the Arctic Regions of the Republic of Sakha (Yakutia)

Abstract

The article deals with the methods for assessment of the environmental, energy, and economic efficiency of the liquefied natural gas (LNG) for the production of electrical and heating power in the Arctic regions of the Republic of Sakha (Yakutia). The basic factors for the development of LNG production and supply to the settlements, which are remote from gas pipelines in the Repulic of Sakha (Yakutia) (Republic), are identified. The authors reveal the advantages of LNG utilization instead of the actually used traditional types of fuel (coal, crude oil, gas condensate, diesel fuel) for diesel power stations and boiler plants in the Arctic regions of the Republic in the context of inter-fuel competition in the production of electrical and heating power. The introduced methods for assessment of the environmental, energy, and economic efficiency are substantiated with experimental calculations in terms of the electrical power production at diesel power plants of JSC Sakhaenergo and in heating power production at boiler plants, which belong to several economic structures, mainly to GUP ZhKKh RS (Y), JSC Sakhaenergo, and JSC Teploenergoservice. As a result, the authors substantiated a method for a comprehensive assessment of LNG effectiveness for the electrical power production at diesel power plants and in heating power production at boiler plants, which are located in 13 Arctic regions of the Republic.
