While
the terms and scope of the pilot aren’t yet defined, it’s part of the
initial stages of what could grow to a pretty big citywide smart
lighting and traffic project. Paris wants to reduce its overall lighting
energy consumption by 30 percent from 2004 levels by 2020, through a
combination of more efficient lighting like LEDs and smarter control
systems. Reaching that goal without instituting unpopular lights-out
regimes or changing the character of the city’s famous nightscapes will
take some clever work.
This
isn’t the only lighting technology project underway for Evesa, a
consortium named after participating companies ETDE, Vinci Energies,
SATELEC and Aximum formed in 2011 to carry out Paris’s grand lighting
efficiency project. Evesa has already been hard at work on revamping the
lighting at famous Paris landmarks like the Place de la Concorde, and
initial reports peg total project cost at between 500 and 700 million
($650 to $900 million).With parkinglotlighting and

Spring's new project is a tiny sliver of that amount, of course.
(Financial details weren't disclosed).
This
particular project doesn’t involve replacing streetlights with LEDs or
other more efficient light sources, he noted. Instead, it's aimed at
networking what's there for increased operational efficiency, which can
actually save more in street lighting costs than energy efficiency
gains. That’s because each networked street light or traffic signal can
deliver useful information to operators, including whether they’re on or
off,Anyone with the space to site a small flatworkironerses can generate their own electricity from wind power. and of course,I have tried several sets of lampshades that have lasted one season only. whether they’re working or not.
That
may sound simple, but compared to today’s mostly dumb street lights,
it’s a vast improvement, allowing cities or utilities to direct
replacement crews to burned-out lights as they happen, instead of
waiting for complaints or on-site inspections to discover the problem,
to name one cost-saving measure. Silver Spring is enlisting the help of
partner Streetlight.Vision,Small itldpcw and supplier UK. which makes streetlight monitoring and control software, for its Paris pilot, Hughes said.

into city networking, he said. Last month it announced a partnership
with LED Roadway Lighting, a Canadian company that makes LED replacement
modules meant to fit into existing streetlight fixtures, for example.
(LEDs are a natural fit for streetlights, since they last longer and run
cheaper than their high-pressure sodium and metal halide predecessors,
and offer a range of digital controls that lend themselves well to being
networked.)
Beyond
energy and operational savings, “there’s a whole spectrum of
applications” for a network that uses ubiquitous traffic lights and
light poles as its nodes, Hughes said. Silver Spring is working on
projects with San Antonio, Texas municipal utility CPS Energy, as well
as with partners in Singapore and Malaysia, that are aimed at expanding
its wireless networks to more end-points in a city, though details are
as yet scarce.
In
Paris, Silver Spring hasn’t yet picked any other specific features it
will be working on with Evesa, Hughes said. Neither have the parties
defined just what communications technologies they’ll use to get there,
he said, though Silver Spring offers multiple networking technologies,
including its RF mesh system now used to network millions of smart
meters around the world and its newer cellular-compatible technology.
Silver
Spring is far from the only company looking to streetlights as the
logical node for citywide wireless networks, of course. San Jose, Calif
based smart grid networking company Echelon has been connecting
streetlights via the company’s powerline carrier (PLC) technology, now
in use by lighting companies like Philips and Osram, and smart meter
players like Sensus and ABB’s Tropos Networks have been adding
streetlights to the list of devices they’re connecting in citywide
wireless networks, to name a few competing examples.
