At present, the influence of technologies on the environment became comparable with natural processes at the Earth. Therefore, the use of renewable energy sources, including water resources, is very important for the energy market operated as the Internet of things. The present paper proposes a universal method for analyzing the efficiency of technical systems using the combination of an optimization method and a method of marginal utility evaluation. Based on the comparison of water volume at a hydropower plant (HPP) and fuel amount at a combined heat and power plant (CHPP) that is used for generation of 1 kW power, it is possible to determine a water price for a HPP. Using the examples of Novosibirsk HPP and CHPP, it is expected to develop an estimation of economic effect from the implementation of the developed criteria, the proposed method of determination of a water price at HPP, and the method of separating fuel costs at CHPP. As a result of implementing the developed method for theHPP, theprice of sold electricity in the flexible energy market will be comparable with the price for sold electricity produced at theCHPP, being equal to approximately 330 RUB/MW·h. Moreover, CHPP are expected to have savings of specific fuel consumption for electricity generation in the amount of 5 g/kW·h and, in some case, 10 g/kW·h. In terms of money, this amounts about 7,350,000 – 14,700,000 RUB per month.
