TEPCO Reaches Smart Meter Milestone

Tokyo Electric Power Company (TEPCO) has deployed more than 20 million advanced meters and intelligent devices, keeping the project on schedule for completion in 2020.

Once completed, the utility’s IoT network is expected to connect close to 30 million utility and consumer devices using a variety of communications technologies and the Wi-SUN home energy management interoperability standard.

The system currently delivers nearly 1 billion data packets daily, which are processed by a meter data management system provided by Landis+Gyr. The system supports a requirement that the network deliver a 30-minute meter read every 30 minutes from each meter.

TEPCO is one of Japan’s the largest electric utilities, serving 45 million people in the Kantō region, which includes Tokyo.

In 2015, TEPCO began a Smart Meter System that included a visualization tool to show the amount of electricity used and simplify changing contract amperage services.

At the time, TEPCO's entire service area had around 2.2 million smart meters installed. The utility set the goal of speeding up installations so that all customer smart meter connection would be installed by 2020.

The smart meters initially provided remote access capability for meter reading as well as for outage detection, accelerating service restoration. In addition, a full day's record of electricity use is measured every 30 minutes and is available to customers on a website, enabling customers to better manage their electricity use.  

The utility also makes available a home energy management system device. It provides twice-hourly updates on electricity use and also offers real-time cost information.

In 2017, TEPCO and Landis+Gyr signed a Memorandum of Understanding to cooperate in building an IoT strategy to develop ways for the utility to monetize itstechnology investments and open new revenue streams.
