Latest City to Install Smart Street Light Network Using Echelon Technology Cuts Energy Use by 35%

(San Jose, CA - December 9, 2009) - Echelon Corporation (NASDAQ: ELON) today announced that the city council of Sénart en Essonne, France, is saving 35 percent in energy use with its new networked street lighting system based on Echelon’s LonWorks® technology. The network of more than 3,100 streetlights can be selectively dimmed by segment during low-traffic hours, helping the city save energy and reduce its annual carbon emissions by an estimated average of 300 tons.

The city council of Sénart en Essonne, an area approximately 35 km south of Paris that includes four cities, signed a performance contract with SPIE, one of the largest streetlight maintenance companies in France, which is leveraging Echelon’s technology to install and remotely configure and program all of the council’s 3,100 energy efficient streetlights in record time. This enables significantly lower installation costs when compared to competitive solutions. SPIE shares the energy and maintenance savings with the city council in a profitable and sustainable relationship.

“The Sénart en Essonne project is a true success. We deployed the solution in record time, showing how easy it is to install our LonWorks-enabled solution. As a result, we are contributing to sustainable development by reducing energy use by more than 35 percent and we are able to anticipate some problems and diagnose them before citizens even know about them,” said Daniel Labanowski, director of business development at SPIE.

“Cities that are investing in intelligent control technology to make their streetlights smarter are seeing real, measurable savings. Remote control can significantly reduce energy costs, and the extra benefits of the network — streamlined operations, lower maintenance costs, improved safety, less light pollution, and enhanced urban environments — may end up being even greater than the energy savings,” said Anders Axelsson, Echelon’s senior vice president of LWI sales and market development.

About the Solution
The Sénart en Essonne City Council selected SPIE, one of the largest streetlight maintenance companies in France, to install and maintain the new streetlight network. The solution includes both OLCs (Outdoor Luminaire Controllers) and electronic dimmable drivers from Philips Lighting. The OLCs are embedded with an Echelon power line transceiver and are able to identify failures, trigger alarms, and take real-time measurements of energy use, number of hours burned, voltage, current, power factor, and power usage. The OLCs are connected to a network of Echelon i.LON® SmartServers to manage the operation of the whole network, called CityNetworks, from SPIE.

Streetlight monitoring software from Streetlight.Vision enables SPIE to easily and quickly configure, install, program, collect data from thousands of streetlights and automatically deliver reports regarding lamp failures, energy analysis and real-time control. The system gives SPIE an overall view of the streetlight system and makes it easy to manage its operation.
