Wi-SUN Alliance was recently selected by TEPCO for its Wireless B route. Over the next ten years, TEPCO will put into place more than 27 million smart meters.
Wi-SUN is a global ecosystem of organizations that creates, interoperable wireless solutions for use in energy management. It is also used for smart utility network applications for the wireless protocol between smart meter and home energy management systems.
A smart meter is an electrical meter that records the consumption of electric energy in intervals of an hour or less. It communicates that information at least once daily back to the utility for monitoring and billing purposes. Smart meters enable two-way communication between the meter and the central system. Unlike home energy monitors, smart meters can gather data for remote reporting.
Back in August, the Wi-SUN ECHONET-Lite specification version 2 became available. It offers multiple vendor implementations that aid in simplifying technology selection. It also helps with installation and maintenance for consumers and custom installers.
Hiroshi Harada of the NICT, Wi-Sun Alliance board explains, "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." Harada is also on the chair of the ECHONET WG.
"This marks a major success for Wi-SUN Alliance. Our members have developed broad global specifications supported by a robust, open, testing and certification process. We have also worked extensively with other stake holders 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," said Phil Beecher, the Wi-Sun Alliance chairman.
