Valence of Electric Energy

This paper presents an easy-to-use method for evaluation of energy from power plants with different output and cost characteristics. The approach described takes into account the suitability of stations for covering a certain demand pattern. It is based on the comparison of generation cost of the power station in question to the cost of generating energy with constant power, expressed by a value factor, and an analysis of the demand arranged to certain groups of daily utilization hours. It permits an easy qualitative evaluation of the effect of different types of station on the development of overall generation costs.
