The Cost

This article presents the basic principles of pricing in the economy, examines the factors influencing the formation of tariffs in the energy sector. Using the example of the Sakmarskaya termal power stantion, the categories that determine the cost of finished products are distinguished. Measures are proposed that can reduce production costs and thereby reduce the cost of electric and thermal energy by about 1.5 times.

Economic Point

Ukraine’s energy system, namely the sector of thermal energy, is the country’s largest producer of greenhouse gas emissions nowadays. Given the significant contribution of Ukraine’s energy sector to the nationwide producing greenhouse gas emissions, the need for its restructuring is becoming increasingly obvious from an economic point of view. However, the lack of economic incentives for private parties and the limited financial capacity of the public sector hamper the implementation of appropriate measures. Given that the natural economic incentives for reducing greenhouse gas emissions from the private sector in the energy sector (80% of the thermal energy sector belongs to the private sector) can only arise in the event of a change in the energy market situation, this raises the question of how to effectively use the limited financial resources of the state for such needs. In view of this, the concept of reducing greenhouse gas emissions in Ukraine’s energy sector is developed, which should be implemented in three stages: (i) the optimization of electricity generation at the TPPs by bringing the load to the maximum and relatively efficient levels, at which the largest amount of energy will be generated per unit of greenhouse gas emissions; (ii) clustering of TPPs into two groups by the performance indicators of operation: the identifying relatively efficient TPPs to be modernized; (iii) ranking of relatively inefficient TPPs by priority for replacement with renewable energy sources. To identify the enterprises in relation to which the proposed measures should be applied, the software is developed, which will determine the relevant information by analyzing the data characterizing the activity of enterprises.

The study presents a methodology for assessing financial risks using projects AMI implementation and ASCOTE in the face of uncertainty. An example of an evaluation of a real project for the implementation of ASUE and ASCUTE systems is presented. The main problems of implementation of this project are considered. In modern conditions of business operation, the decisionmaking process is based only on the experience and intuition of experts is currently not effective. We must use modern information technologies, which have already received the generic name «decision support systems for management decisions». Taking into account the weak formalization of such tasks, it is necessary to apply methods of system analysis with the involvement of expert assessment technology, both at the initial and final stages of obtaining and choosing the most rational alternatives to management decisions. The tasks of improving the accuracy and efficiency of measurement of electrical and thermal energy, power in electrical networks, the amount of thermal energy in thermal networks are due to the following main reasons: firstly, a significant increase in the cost of electrical and thermal energy, secondly, the reforms carried out in the energy sector of the Russian Federation, thirdly, the fair billing. The research is devoted to the analysis and assessment of the priority of ASUE and ASCUTE functions. The Association of risk subsystems and functions in a single multi-level system. Based on the analysis of binary relations, an integrated model of the risk-function system in the form of a hierarchical tree structure is obtained. Applied the method of paired comparisons in the assessment of risk hierarchies that affect the effectiveness of the projects. The paper presents approaches to solving problems related to organizational and technical reengineering of production, which is due to the weak structuring of these problems, from the formation of goals to the adoption of technical and managerial decisions.

In the global energy sector, there is a steady trend towards an increase in the production and consumption of energy. As the analysis of the technology has shown, mini-Thermal Power Plants (TPP) are one of the key solutions to the problem. The construction, as well as the reconstruction of existing boiler houses in the mini-TPP will not only ensure more efficient use of fuel through the combined production of electric and thermal energy, but also improve the reliability of power supply to settlements and industrial enterprises
