In this work, a technical and economic comparison of options for the technical design of an integrated heating and cooling system in the Yakutsk city was carried out. A qualitative and quantitative assessment of the socio-economic, modes and environmental effects of the operation of an integrated heating and cooling system was obtained. The discounted payback period was six years for the option of decentralized cooling with local installation of absorption chillers. The use of waste heat by absorption chillers in the production of cold can reduce electricity costs by up to 29% per month of total consumption and save up to 519 million rubles per year. The introduction of integrated heating and cooling technology can reduce CO2 emissions by up to 58 tons.

The direction of Russian energy towards decarbonization and reduction of CO2 emissions creates the basis for the development of alternative technologies for generating energy resources. In turn, rising global average temperatures contribute to increased cooling degree days and increased air conditioning demand. High heat load in winter, gas turbine units at power plants in Yakutsk, a significant amount of waste heat in summer and the need for cooling are indicators of the efficiency of trigeneration based on absorption chillers. In view of these reasons, the technology of an integrated heating and cooling system is proposed for implementation in regions of the North with cold winter and hot summer. A tool has been developed for the development of this technology: a map-scheme of pipeline systems for district cooling system in the city of Yakutsk with reference to the area. The lengths of district cooling pipelines and cold loads of consumers were calculated. The information can be used in technical and economic calculations and specialized software packages for hydraulic calculations.

In 2023, the energy problems department Larionov Institute of the Physical-technical Problems of the North celebrated its 65th anniversary. This article briefly presents the experience of the department for system research on the development of energy in the Northern region, including integrated energy supply systems, in addressing the challenges of development and operational management. The primary focus is on the energy research conducted by department over the past five years.

This article presents a systemic analysis of the challenges and strategic priorities for modernizing the energy sector of the Republic of Sakha (Yakutia). The relevance of this research is driven by the unique constraints the region faces, including an extreme climate, protracted fuel supply cycles, a high share of isolated power systems, and increasing fiscal pressure from the need to subsidize inter-tariff cross-subsidies. The methodological framework of the study is based on a systems research approach applied to the energy sector. The article proposes an approach that integrates operational measures for stabilization with a long-term technological transformation. Key strategic vectors identified include: modernizing conventional generation, deploying integrated heat and cold supply systems, actively harnessing renewable energy potential, and leveraging R&D in new materials and predictive diagnostics.
