Technological and Economic Evaluation of the System of Heat Supply with the Usage of Renewable Sources of Energy

摘要

Further development of power engineering may be with the usage of renewable sources of energy. For this purpose a number of stimulating measures on active usage of renewable energy are worked out and functioned. The development of renewable power engineering is on the way of production of electric power with the great power facilities. In heat power the renewable energy is little used on different reasons, in particular because of the development of decentralized system of heat supply, the part of which is 57% in Russia. It makes definite difficulties in search of interested investors. The results of research on defining the economic indices of the system of heat supply on the example of the usage of low potential heat of the groundwater with the help of heat pump installation are shown in the article. Existing methods of economic evaluation of projects using renewable sources are given. On levelized cost of heat energy the effectiveness of using heat pump installation in the conditions of South Ural in 50% providing with consumer heat energy is proved, remaining part is provided with the burning of traditionally used energy resource.
