Abstract

Fulfilling the decision of the Paris Agreement on Climate Change (COP-21 of the UNFCCC) dated December 12, 2015, the government of the Republic of Uzbekistan has developed and adopted an energy development plan of the Republic for 2020-2030. The plan provides for the construction of 3 GW of wind and 5 GW of solar power plants annually. RES will generate electrical energy in parallel with the generation of energy by thermal stations and transfer it to the general energy system. The main disadvantage of the joint operation of RES and thermal power plants is the need to have standby generating capacity due to the fact that the sources of solar and wind energy are fickle by nature. System costs rise with the increasing share of renewable energy sources. The Solar Updraft Tower project is a renewable energy option that does not have the main disadvantage of other types of renewable energy sources - the variability of electricity production and therefore is more acceptable for operating conditions in a single energy system. The article discusses and evaluates the Solar Updraft Tower (SUT) project for the generation of electrical energy, taking into account the conditions of Uzbekistan.
