“…The main ones are oil, natural gas, coal, combustible shale, as well as the power of water, wind, sun and the like. At the same time, their economically feasible development leads to a constant search, mastering and improvement of technological and technical solutions [1][2][3]. For example, when mining coal reserves using traditional technologies, the scientific-practical work is constantly being carried out to improve the mining process.…”

This paper studies the relevant issues of innovative projects implementation, in particular, during the prospective development of coal reserves by geotechnology of underground gasification. To solve the objectives set in the work, an integrated approach is applied, which includes: critical analysis, generalization, systematization and synthesis to determine the phases and stages of the innovative project implementation; conducting econometric modeling to calculate the total effect from the implementation of innovations. The conducted research has proven that it is important to determine the phase and stage of an innovative project in order to increase the efficiency of its assessment. The prospect of introducing geotechnology for underground gasification has been revealed, which in conditions of “pre-investment” uncertainty is associated with the lack of reliable information on the choice of priority directions and methods of practical use of innovation (based on the experience of industrial research and the operation of closed coal gasification plants). An integrated system of indicators for assessing the effectiveness of innovative project at the stage of its implementation has been developed and an algorithm for determining the total effect from its implementation has been proposed.

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.
