Assuming a linear increase in the tariff, the relationship between the levelized cost of energy of thermal power plants (LCOE) with the growth rate of the emission tariff, technical parameters of thermal power plants, time frame and interest rate of the project. For different types of thermal power plants, grouped by the value of the coefficient of conversion of thermal energy into electricity, the reduced cost of electricity in medium-term and long-term projects using the main fuels. The level of profitable investments in the reconstruction of thermal power plants is estimated at the increase of the tariff for carbon dioxide emissions. High efficiency of TPP reconstruction in medium-term projects is substantiated, which allows to achieve significant reduction of gross CO<sub>2</sub> emissions with constant production volume and constant value of LCOE. The efficiency of investments in the reconstruction of thermal energy and in renewable energy to reduce CO<sub>2</sub> emissions is compared. It has been shown that investments in the reconstruction of thermal power plants give the greatest reduction in CO<sub>2</sub> emissions per unit of investment compared to alternative projects. At the same time, the reconstruction of TPPs increases the shunting power in the United Energy System of Ukraine, which will allow more active implementation of renewable energy sources for electricity generation. The possibility of using ammonia as a fuel for thermal power plants to reduce carbon dioxide emissions is discussed. The importance of thermal power plants to ensure the sustainable operation of the United Energy System of Ukraine in today’s conditions is emphasized. <em>Bibl</em><em>. 18, </em><em>Fig</em><em>. 1, </em><em>Tab</em><em>. 4.</em></p&gt;}, number={3}, journal={Energy Technologies & Resource Saving}, author={Volchyn, I.A. and Kvitsinsky, V.O. and Marushchak, S.V.}, year={2022}, month={Sep.}, pages={40-57} }
