High Voltage Customer Service Portal

1.　Introduction

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 (https://service.taipower.com.tw/hvcs/) 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.

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.

The following are website features. Detailed functions are illustrated in next section.

• Real-time electricity consumption information

  Customers can fully know their power consumption through real-time and complete information offered by the website and plan to reduce electricity costs.

• Evaluation of Energy-Conservation efficiency

  By using calculation function, customers can evaluate how to participate in demand response measures to reduce their electricity costs.

• Responsive Web Design

  This website adopts Responsive Web Design (RWD), which can automatically adjust the screen configuration according to the mobile devices such as the mobile phones or tablets used by the customers. It helps customers use the website anytime.

• Data visualization

  Customers can query the power consumption of recent periods compared to other periods by charts.

• Electricity simulation

  Using historical electricity data to simulate the future power consumption will help customers understand the load of their equipment.

• Benefits of digitalization

  Evaluate the benefits of customers participating in demand response management measures and help them change their power consumption or production schedules to reduce the consumption usage of peak load.
