The article discusses the characteristics of the glacial zone and the zone of formation of river flow in Tajikistan due to climate change. A special role in the context of climate change is assigned to the development of a conceptual model of optimal management to ensure water and energy security of the Republic of Tajikistan at the organizational level, technical and economic levels. The aim of creating a conceptual model is to manage large reservoirs with multi-year regulation for power generation and river flow, create conditions for the accumulation of water during high water periods and increase the water content of rivers during low water periods. The implementation in practice of the idea of a conceptual management model ensures optimal control of the water-energy system. The advantage of the model is the transition from the command-administrative method of management to the systemic method of management in the aisles of hydrographic, energy and consumer parameters.
