The pricing of electricity is of great significance in resource configuration, energy-saving, emission reduction, enterprise development, and resident life, et al. The analysis is performed from both sides of electricity consumer and producer. Based on customers’ individual requirements, the ladder power optimization model is established with maximum customer satisfaction. At the same time, based on the Ramsey pricing theory, the ladder price of electricity is made. And consideration is given to both power enterprise’ breaking even and changing needs for all kinds of users, then the federation model of TOU and ladder price is proposed. The analysis of an example shows that the federation model is advantageous for rational power consumption, peak clipping and valley filling, and reflects the principle of fair sharing of the cost.
