ECONOMIC EFFICIENCY EVALUATION OF WIND ENERGY INSTALLATION INTRODUCTION AT AN INDUSTRIAL ENTERPRISE

Abstract

In the conditions of permanent and rapid world energy prices growth, the electricity generation using renewable energy sources (RES) introduction is becoming increasingly important. Given Ukraine's aspirations to join the European Community, incentives for electricity generation through RES have been introduced at the state level. The main tool of electricity producers’ stimulation is the "green tariff". Its size significantly exceeds the cost of purchasing electricity from traditional generation sources, which contributes to the development of this area of energy. At the same time, insufficient attention is paid to the own electricity generation introduction based on RES by industrial enterprises, which has become especially relevant given the rapid rise in natural gas prices in 2021 and the corresponding increase in prices for other energy sources. The goal of this article is to study the feasibility of a wind farm introducing to meet industrial enterprises electricity needs. The objectives of the study are to analyze the wind energy using advantages and disadvantages and practical aspects of such equipment use, assessing the possibility and feasibility of using it in an industrial enterprise under the "green" tariff. The economic aspects of such an innovation are also considered. The required electrical power of the furniture production enterprise needs have been calculated. The economic substantiation of expediency of wind power plant for full maintenance needs in the electric power is carried out. Calculations of the required power plant capacity, wind speed, payback period of investments have been made. The results of the study can be used to decide alternative power sources introduction in similar enterprises. And also can be taken as the plan of electrification basis for enterprises of other branches. Further research is planned to consider to options for the solar power plants, hybrids of solar and wind power plants introduction to meet the individual industrial enterprise’s needs, as well as batteries to store excess energy and equalize the generating capacity utilization in conditions of daily load fluctuations.
