Requirement for power differs throughout the day, improving the average cost of power source. A timeof-use (TOU) expense has been suggested as a demand-side management (DSM) technique to influence customer requirements. In this paper, we explain a game-theoretic approach to improve TOU expenses strategies (GT-TOU). We recommend designs of expenses to power organizations coming up from customer demand fluctuations, and designs of customer fulfillment with the difference between the affordable demand and the actual intake.
