TEPCO adopts Wi-SUN specification for Wireless Smart Utility Network

TOKYO, October 3, 2013 – The Wi-SUN(R) Alliance, a global ecosystem of organizations creating
interoperable wireless solutions for use in energy management, smart-utility
network applications, today announced that the Wi-SUN Alliance specification
for the Wireless protocol between Smart Meter and Home Energy Management
Systems has been selected by TEPCO for its Wireless B route. TEPCO will deploy
27 million smart meters over the next 10 years.

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

“The Wi-SUN Specification is the most robust, reliable and scalable low power
wireless standard for Home Energy Management Systems, and the technology of
choice for world-leading service providers, installers and retailers,” said
Hiroshi Harada, NICT, Wi-SUN Alliance board co-chair and chair of the ECHONET

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