Problems of development of renewable energy sources in the energy system of Russian regions (based on materials from the Khabarovsk territory)

The article presents the problems of the power systems of Russia. Problems such as the aging of the existing energy systems, the lack of centralized power supply in remote areas of the country, the high cost of electricity and environmental pollution are highlighted. The article considers the barriers to the development of renewable energy sources as one of the most relevant today ways of solving the selected energy problems of the country. The factors contributing to the accelerated development of renewable energy sources in Russia are given. One of the main barriers to the development of renewable energy sources is their insufficiently studied economic efficiency. The approaches that exist in the scientific world are highlighted for substantiating the economic efficiency of energy facilities. On the basis of the selected approaches, a substantiation method was used, including the monetization of environmental and climatic effects. An assessment of the economic efficiency of three operating power plants is given on the example of the Khabarovsk Territory. The analysis showed that today none of the considered power plants is profitable in the existing market conditions. However, according to the initial technical characteristics, a solar power plant is already the most profitable compared to diesel and coal in decentralized areas. And when included in the carbon monoxide tax calculation, renewable power plants become even more attractive than conventional power plants.
