Energy security assessment when introducing renewable energy technologies

Abstract

Large-scale introduction of energy-saving technologies, especially renewable energy technologies, is closely linked with the problems of energy independence of domestic enterprises. In implementing the latest energy-saving technologies, including advanced technologies of conversion and utilization of renewable energy such as solar energy, heat from venting emissions and etc., forming a kind of the system of enterprise energy security indicators is necessary. Based on certain indicators, enterprise energy security strategy can be evolved in the future taking into account the principles of sustainable development. To select the best embodiment of the energy supply systems using renewable energy, a set of requirements that will provide effective technical support of the production process were defined. The system of interconnected stages, which allows the energy security investigation was identified. The method, which suggests using an indicative method, qualimetric assessment, decoupling etc. to calculate the integral index of the enterprise energy security was proposed. Qualimetric assessment of the enterprise energy security is carried out in the following stages: forming a hierarchical system; expert evaluation of the weight (importance) indicators: combining quantitative and qualitative estimates by certain rules into the overall estimate of the object. In the study of the system of the enterprise energy security indicators, consideration of the 'effect decoupling', which determines the need to change processes, especially when using renewable energy sources is important. The obtained indicators can be used in the future when forming the enterprise energy security strategy. Reduction of the indicator value indicates the degradation of the enterprise energy security. Using indicators when developing the energy supply strategy, including utilization of renewable energy will promote systemic saving of fossil fuel, reducing the harmful effects of energy systems on the environment and energy supply stabilization.
