In the Republic of Sakha (Yakutia), 19 solar power plants with a total capacity of 1.6 MW are operated. The saving of diesel fuel by solar power plants in 2017 was 300 tons worth 17 million rubles.

The introduction of alternative energy sources is possible only with the involvement of outside investors. Now a number of such projects are being implemented.

In the village of Tiksi, a project for the construction of a wind-diesel power plant with a total capacity of 3.9 MW is being implemented. The project is being implemented within the framework of the signed documents between the Republic of Sakha (Yakutia), PJSC RusHydro and the New Energy and Industrial Technology Development Organization (NEDO) of Japan. This year, it is planned to deliver and install 3 wind turbines with a total capacity of 900 kW, in 2019 - 3 diesel generators of 1 MW and energy storage systems.

In July last year, the Republic of Sakha (Yakutia) and the Hevel Group signed an Agreement on cooperation in the field of electricity supply to isolated settlements of the Republic of Sakha (Yakutia) through the construction of autonomous hybrid power plants based on solar energy. Currently, work is under way to identify the facilities of diesel power stations proposed for modernization.

Besides, the work of renewable energy sources in combination with diesel power plants only reduces the amount of diesel fuel consumption. It is impossible to completely abandon the import of diesel fuel through the construction of renewable energy sources.

Two-thirds of the territory of the republic belongs to the decentralized energy supply zone, which is inhabited by less than 100 thousand people - the so-called Northern Energy District, which includes the Arctic and Northern regions of Yakutia. Here, the main source of electricity is isolated local diesel power plants.

Central, Western and Southern Yakutia are located in the zone of centralized power supply. Here, electricity generation is carried out by large stations - the Cascade of the Vilyuisky HPPs in the West, YAGRES-1 (Yakutsk Hydro-Electric Power Plant) and YAGRES-2 in the Center and Neryungi GRES Power Plant in the South. Since 2019, these three power districts will be merged and will enter the United Energy System of the Far East.

In November of last year, the first stage of YAGRES-2 was launched. The launch of the first stage of the YAGRES-2 became the most important event for the republic, the commissioning of new facilities significantly increased the reliability of the power supply of the Central Power Region of the region, including the capital of the republic - Yakutsk. The launch of the first stage was necessary to create a reserve for electric power, as well as to replace the retired capacities of the Yakutsk Hydro-Electric Power Plant, the equipment of which exceeded its performance potential, providing more than 90% of the electricity consumption in nine districts of the republic (population of more than 500 thousand people), and more than 50% of Yakutsk.
