Abstract
In the present paper the scheme for increasing the energy efficiency of combined heat and power plants (CHPP) using absorption heat transformers (AHT) is considered. The aim of the study is to increase the energy and environmental efficiency of natural gas use in power supply systems by application steam turbine plants and absorption heat transformers. The simulation of CHPP modernization and a harmful emissions dispersion assessment were carried out using the following software tools: ISC Manager, Thermoflex. All the calculations were made for one power unit of the CHPP in Moscow. Subsequently, the obtained data on energy efficiency increase and harmful emissions reduction were multiplied on the whole power system of Moscow, the main source of heat and electricity of which are the CHPP’s of PJSC “Mosenergo”.

Energy-efficient and environmentally friendly production of heat and electric energy is the key to the development of society and improving people's living standards
Industrial Source Complex (ISC) is recommended for use by the US Environmental Protection Agency (EPA)
The data presented in table 3 give a clear idea of the environmental effect of modernization using absorption heat transformers (AHT) of all combined heat and power plants (CHPP) plants owned by Mosenergo PJSC
Summary
Energy-efficient and environmentally friendly production of heat and electric energy is the key to the development of society and improving people's living standards. There are examples of the use of absorption heat transformers at thermal power plants These are coal stations in China, none of which can be built without using AHT on them. It should be noted that articles [1,2,3,4,5] are based on data on coal-fired thermal power plants that are used in China, and there are practically no studies on the use of AHT on gas-fired thermal power plants specific to our region In this regard, modeling the modernization of a real thermal power plant to obtain reliable data on the energy and environmental effect of such modernization is a paramount task for the energy-efficient and environmentally friendly development of the fuel and energy complex (FEC) of Moscow, in particular, and Russia as a whole. As a first step to calculate the effect of the modernization of the CHPP, an analysis of the energy system of Moscow was carried out
