A significant share of nuclear generation in total electricity production, an increase in the share of renewable energy sources (wind, solar, etc.), variable electricity consumption schedules and changes in electricity prices in the market necessitate the use of thermal power plants in load control mode. Using the method of calculating equivalent operating hours to account for the reduction of the service life of the main equipment, the efficiency of thermal power plants in variable modes was studied. The equivalent operating hours of the K-300-240 turbine and the prime cost of electricity of the steam turbine power unit were calculated when operating in the nominal and sliding steam pressure mode depending on the level of unloading and the rate of change of output power.
