We analyzed the technical state and characteristics of work of the power units of Ukrainian thermal power plants. We found significant changes in the operating conditions of power units (equipment aging, low maneuverability in regulating the schedules of electrical loads in the united power system, fuel problems), which led to an increase in specific fuel consumption for electricity generation, a decrease in the utilization factor of installed capacity, and an increase in harmful emissions to the environment as compared with the world level. The influence of maneuvering modes of operation on the additional gas consumption at TPPs is estimated. Comparison of current emissions of flue gases with the technological norms of permissible emissions from separate power units and TPPs is carried out. The plans of development of heat power facilities of Ukraine concerning the minimization of negative factors in the work of thermal power plants are analyzed. Transition to new technologies in the heat-and-power sector can provide an increase in both energy and economic efficiency as well as environmental safety due to the reduction of harm ful emissions to an acceptable level (according to Directive 2010/75 / EU).
