Landis+Gyr Announces 20 Million Meter Milestone at TEPCO

World’s largest smart grid deployment on track for completion in 2020

ATLANTA, GA. – March 4, 2019 – Landis+Gyr (LAND.SW) announced that the deployment of advanced meters and intelligent devices at Tokyo Electric Power Company (TEPCO) has eclipsed 20 million, keeping the project on schedule for completion in 2020.

Upon project completion the utility’s IoT network, the largest of its kind currently deployed, will connect close to 30 million utility and consumer devices using a variety of communications technologies and the Wi-SUN home energy management interoperability standard. Currently the system is delivering nearly 1 billion data packets daily, which are processed by the Gridstream® meter data management system. Supporting a requirement that the network deliver a 30-minute meter read every 30 minutes from each meter, the Gridstream head-end system has demonstrated the ability to manage more than 30 million meters.

“We’ve learned a great deal from supporting a project of this size and the requirements for flexible network communications, and that’s driven our strategy for our Gridstream Connect platform and future utility IoT offerings,” said Prasanna Venkatesan, President and CEO of the Americas region at Landis+Gyr. “We look forward to our continuing work with TEPCO to support Japan’s energy management vision.”

TEPCO is the largest electric utility in Japan. The utility provides electric service to 45 million people in Japan’s Kantō region, which includes the city of Tokyo.
