On September 2, 2018, Chubu Electric Power’s online service “KatEne” started a new function that calculates and visualizes the electricity usage of each household appliance in a home. Customers can check the electricity usage share of home appliances like air conditioners and electric water heaters without needing to install any additional measuring instruments.

The service is offered for free to customers who installed smart meters in their house. This service collects information such as electricity usage data obtained from smart meters, the current installation situation of household appliances, the outdoor temperature, and the local sunrise and sunset times. Using its own in-house methodologies, Chubu calculates the electricity usage rate of each household appliance and the approximate electricity charge, enabling customers to understand their energy consumption and energy savings.

The “KatEne” service, launched in 2015, is a household customer online service aiming at promoting energy consumption through visible energy-saving information. By the end of March 2019, Chubu also plans to implement add-on functions for customers that have installed solar panels, which will calculate those customers’ precise energy consumption and billing information, and will reflect the energy generation amount from their installed solar systems.
