Tokyo, Japan --- (METERING.COM)

Tokyo Electric Power Company Inc. (TEPCO) has become the first utility to select the Wi-SUN specification for the wireless protocol between smart meter and home energy management systems for the wireless B route of its 27 million smart meter deployment.

The Wi-SUN ECHONET-Lite specification version 2 was made available for product development in August 2013. The specification provides for fully interoperable, multiple vendor implementations helping to simplify technology selection, installation and maintenance for consumers and custom installers alike. It includes an authentication and encryption process between smart meter and home energy management system (HEMS), and between HEMS and home electrical appliances.

“This marks a major success for Wi-SUN Alliance,” said chairman Phil Beecher. “Our members have developed broad global specifications supported by a robust, open, testing and certification process. We are honored that TEPCO, one of the world’s largest utilities, has provided this validation of the value of our collaborative, global, process.”

TEPCO’s smart meter rollout is planned over the next 10 years.
