Echelon and Partners Showcase the Future of Energy Efficient Streetlight Solutions at LumiVille 2009

LYON, France--(Business Wire)--
Echelon Corporation (NASDAQ:ELON) and 10 partners are showcasing LonWorks® based
energy saving and control applications at the 2009 LumiVille event, May 26-28 in
Lyon, France. LumiVille is the premier exhibition in Europe dedicated to
external and public lighting.

Networked streetlights are a hot market segment with the addition of smart
control technology because they extend the smart grid to one of the core pieces
of a city`s infrastructure - adding energy intelligence, better manageability,
and improved safety.

At LumiVille, Echelon and its partners will focus on showing streetlights
networked with Echelon`s intelligent controls for smart networks, which can
significantly reduce a city`s energy and maintenance costs while improving light
quality, decreasing light pollution, and providing increased safety.

LumiVille marks the public debut of two startup companies in the networked
streetlighting market - SCS Streetlight Control Solutions and Citylone. Both
companies are using Echelon`s power line signaling technology and i.LON®
SmartServer segment controllers to deliver IP and ISO/IEC standards-based
streetlight solutions to cities.

"We believe that the market is ready for smarter streetlights that can reduce
energy use and lower maintenance costs," said Bernard Delhomme, Citylone`s chief
executive officer. "In fact, we believe that smart streetlights are just the
beginning and that cities will leverage streetlight networks for other uses to
take advantage of the open infrastructure that we provide. We chose to base our
new streetlight solution on Echelon`s LonWorks technology because it is the best
overall platform, standards-based, and it is a proven, reliable technology, with
over 20 years of experience in the control industry."

"The view of the smart grid has expanded greatly since the term became popular,"
said Roman Francesch, general manager of SCS. "Smart streetlights are an
extension of the grid - consuming huge amounts of a city`s overall electricity
use. SCS was founded on the belief that LonWorks-based smart streetlights will
be a primary infrastructure for a city for decades to come."
