The base load demand in the short term cannot be met because of the soaring of international raw materials, and oppositions on building new base load generator sets, namely coal and nuclear plants. Thus, the insufficient demand is forced to be filled by activating diesel and gas generators, which consequently, increases the cost of power generation annually. There are approximately 13 million electricity customers in Taiwan; however, only 23 thousand of which are high-voltage users, who consumes about 58% of the total electricity generated. Therefore, the construction of AMI(Advanced Metering Infrastructure) has prioritized for those users. The basic function of AMI is to record the status of power consumption and power quality. This paper uses the recorded data with the peak demand on 15-min interval bases to guide the customers in transferring load from peak-hours to off-peak hours. This way, off-peak demand is steadily increased which ultimately optimizes demand utilization and solves the bottleneck of electricity shortages. Moreover, with the AMI as a fundamental, portal web service for high-voltage users can be provided in the future. Customers can inquire electricity consumption data and calculate demand needed from the site, as well as granting Taipower the ability to develop electricity tariffs that provides incentives for customers to participate in energy saving and carbon reduction, which conclusively, lower the generation cost.
