Results of circuit decisions on utilization of waste energy (WE) of compressor stations (СS) of gas-main pipeline for increase of operating efficiency of gas-compressor units (GCU) are resulted. Thermal WE are the products of fuel gas combustion of gas-turbine engines (GTE) working on CS. WE is possible to effectively utilize in plant «Vodolej» for increase of GTE efficiency. It is offered for this purpose a plant «Vodolej» to add by absorptive refrigerating machine with the purpose of increase of GTE efficiency at their work during the hot period of year. Variants of increase of operating efficiency of GTE are considered by means of others heat-disposal plants. The time of recoupment from introduction of heat-disposal plants into technological circuits of CS with five GTE by results of preliminary technical and economic calculations does not exceed three years.
