Cities Across France Using Echelon based Smart Street Lighting Systems

May 01, 2011 by Jeff Shepard

Echelon Corp. announced that its energy control technology for smart, networked street lighting systems is continuing to experience rapid adoption. Similar to its success in China, the market in Europe, and in particular France, is recognizing the advantages of Echelon intelligent distributed control solutions using power line communications (PLC) for reducing energy consumption and maintenance costs of municipal street lighting. The street lighting solution includes Echelon’s power line signaling technology for distributed control, Echelon SmartServers for segment control and enterprise connectivity, and system software from French company Streetlight.Vision.

Studies have shown that as much as 40% of city energy budgets go towards lighting streets and that a streetlight is responsible for emitting an average of 200 kg of CO2 every year. Energy savings, carbon reduction, lower operating costs and a general push by state and local governments for greener cities are all driving the decision to move to advanced control networking technology that enable cities to dynamically dim their lamps to save significant energy and reduce their carbon footprints.

"Even though France has one of the lowest electricity prices in Europe, many cities and French streetlight maintenance companies are deploying smart and controlled street lighting solutions," said Christophe Orceau, General Manager of Streetlight.Vision. "About 30,000 lights have been equipped with Echelon PLC transceivers together with the Echelon energy control network platform in 2010, and we have the opportunity to have nearly 250,000 installed by 2013. Thanks to Echelon’s technology, smart street lighting solutions are easy to deploy and provide energy saving as well as maintenance saving benefits both to cities and to streetlight maintenance companies. With energy savings up to 45% on our projects in France, smart streetlights are a perfect fit with PPP, MPE, EMC and ESCO types of contracts."

Most projects in France have moved beyond a desire for an energy efficient lamp to a requirement for system-wide intelligence and control. French cities including Lyon, Brest, Moissy and the RSEIPC (an organization that manages 20,000 streetlights close to Chartres) have specified Echelon compatible smart street lighting in their tenders. This is in addition to more than 60 large and small cities in France that have deployed an Echelon based streetlight monitoring system in 2010 on part or throughout their streetlight network. This adoption is up significantly from the 15 cities that deployed Echelon based street lighting in 2009.

"The French cities are leaders in improving energy efficiency and lowering carbon footprint on their street lighting networks, while improving safety in the streets," said Anders Axelsson, Echelon’s Senior Vice President, Commercial Markets. "We understand that in addition to helping provide these benefits, a key driver behind the adoption of Echelon based solutions is that it is the only open, multi-supplier solution on the market. This means that cities can select from among dozens of manufacturers of light controllers and not be bound to a single manufacturer, which is the case with proprietary systems."
