Echelon Corporation (
ELON) today announced that the Japanese Government has selected ITOCHU Corporation, a leading Echelon distributor and one of the largest Japanese corporations engaged in
Smart Grid and Smart City projects, to deliver an
intelligent streetlight system to the city of Tsukuba, located in the Ibaraki Prefecture. ITOCHU will deploy the Echelon and Streetlight.Vision energy control networking solution, the first system of its kind in Japan, to help reduce power consumption, increase safety and security, and to enable the City to achieve operational savings.
This deployment will be part of the Japan Ministry of the Environment's "2011 Challenge 25 Regional Development Project" to reduce global warming and contribute to environmental conservation. In this initial deployment, streetlights will incorporate Echelon's proven
Power Line Communications (PLC) technology, and communicate with
segment controllers running over the established power line infrastructure. The segment controllers running Echelon's
Control Operating System (COS) and the Streetlight.Vision Control, Command & Monitoring software will execute local streetlight control decisions at the edge of the grid. Management software running in the data center will provide the policy setting and visualization environment. Overall, the system will monitor energy consumption, save energy by dimming individual light points, improve public safety by adjusting lighting schedules and intensity as required, and simplify maintenance and replacements by identifying failures and anomalies on the streetlight network. As a result, Japan will have its first foundation for building out the street lighting network as part of its smart city infrastructure.
"Smart street lighting using PLC continues to attract our customers because it enables a tremendous cost savings by allowing them to use existing power lines to transmit data, eliminating the need to lay new communications lines," said Tomohito Arai, general manager, Information Technology Business Department, ITOCHU. "With our partners Echelon and Streetlight.Vision, we will not only help reduce power consumption in the City, we will also maintain proper safety and security, which is an issue in Japan due to reduced availability of street lighting after this past year's natural disasters."
