Influence of technical and economic factors in the assessment of energy efficiency projects in industry

Assessing the feasibility of implementing an energy efficiency project shall be made by the quantification of energy savings. Energy savings can lead to reducing the fossil fuels use and can quantified by using an economic criterion, e.g. payback period. There has been performed a technical and economic analysis for the implementation of energy efficiency project for a technological process. In this paper the variation in time of different technical and economic criteria that can influence the energy and economic efficiency of a technical solution was analysed.
