In this paper, it is proposed to introduce technology of an integrated heat and cold supply system in Yakutsk city. Classic option of district cooling system (DCS) with use of absorption chillers is considered. The integrated energy system work of Yakutsk for 3 months of 2019 summer is modeled. Simulation results showed there was enough waste heat to operate absorption chillers for entire time of the DCS operation, even for maximum possible cold load of the city. The calculations showed possibility reducing the city's electricity consumption up to 20.0%. Primary economic indicators showed that the project would be economically successful if there was sufficient demand for cooling.

The consumption of electrical energy by electrical installations of a commercial enterprise is considered. An analysis of the consumption of electrical energy showed that the consumption of electrical energy per square meter of the enterprise exceeds the average in Russia. Possible ways of energy saving are revealed. Measures for energy saving in various technological processes are proposed, through the use of modern energy-saving technologies and equipment in lighting installations, in the processes of cooling perishable goods, air conditioning, and plant management. The effectiveness of the proposed measures was evaluated.
