Study on the Value of Business Option of Surplus Energy Possessed by Energy Prosumer under Dynamic Pricing

Abstract

In this research, we describe the business options that prosumer can possess for “surplus energy” under dynamic pricing. We analyze the value structure from the viewpoint of the two business options, short-term repeat business option “power sale timing option” and long-term business option “power storage equipment installation option”. Considering the value structure of “power storage equipment installation option” to be the business option with additional value based on “power sale timing option” as the underlying asset, we analyze factors of change in value due to the uncertainty of the electricity price fluctuation range. The sensitivity analysis by the case study shows the tendency of increase in option value due to fluctuation of electricity price. In addition, the tendency of change in option value due to capacity of power storage equipment is shown.
