Website Service

High Voltage Customer Service Portal


The peak load of Taiwan power system is daytime (10-18) during summer. Besides Taipower’s dispatch to remain system reliability, customers’ awareness of energy saving is also needed. In the case of high-voltage customers were fully deployed with AMI, Taipower has used communication technologies to build High-voltage Customer Service Portal ( to provide customers value-added services and create a win-win situation for the company and customers.

The frequency of transmission time from customers’ installed AMI to Taipower is daily. Through information and communication technology (ICT) and analysis, the data would eventually be presented by visual charts to users, shown as Fig.3.

The website was officially launched in July 2016, which can help high-voltage customers manage power by themselves and help them control power consumption and electricity costs. The customer can apply for an account by MOEACA Application online or at the counter.

TPC e-Bill service

 ◆Service Description

The TPC e-Bill service with simple registration and customer number setting has been provided to TPC users for quick inquiry of power consumption data and easy bill management. It is presented via easy-to-understand electronic interface and micro-animation such that users can have quick access to bill related information to facilitate the self-management of amount power consumption behavior and to achieve the energy saving effect.

The main visualization design of the front page is based on the illustration style (as shown in Figure 1, 2, 3, 4) with the layouts of four seasons. And there are the renewable energy subjects of wind power, solar energy, and hydraulic power generation to attract users to TPC e-Bill service in order to achieve the goal of paper reduction and environmental protection.

 ◆Function Description

  ◇General User

“General User” can have access to the website related information including payment status enquiry, bill pre-estimate, website tutorial, FAQ and news. (as shown in Figure 5)

Figure 5 Front page of TPC e-Bill service


Users can register to become the “Member” of TPC e-Bill service. In addition to periodic bill notification and payment certificate in the form of email, users can also have access to historical bill data.

A member could login the TPC e-Bill service to have access to the functions of basic information management, bill inquiry, and analysis of amount consumption chart. To make the operation easily, the bill information of all registered customer numbers will be listed on the login screen, and the provided functions are the latest monthly bill, total amount, payment status, the payment barcode to be downloaded (the unpaid bill can be directly downloaded), re-sending of electronic notification, and historical data.

 ◆AMI Real-Time Inquiry

To facilitate the real-time inquiry of amount consumption data by AMI smart meter users and thus promoting the power consumption management, the “AMI Area” icon behind the customer number of AMI could be selected to enter the AMI dashboard function, which provides various functions such as comparison of various real-time amount consumption data, self-defined upper limit of amount consumption, analysis of amount consumption statistical chart, and rate service evaluation (as shown in Figure 6).

Note: Users could enquire real-time amount consumption data of the previous day by noon.
