Oslo to cut streetlight energy costs by 30% while increasing safety

April 7, 2006 The City of Oslo (Norway) is developing an intelligent outdoor lighting system to remotely control and monitor streetlights. The first large scale implementation of a control network in a street lighting application in Europe, the system is expected to reduce energy usage by 50 percent, improve roadway safety, and minimize maintenance costs. The project calls for the installation over the next three years of 55,000 intelligent street light ballasts that communicate over existing power lines with Internet Servers acting as segment controllers, which in turn communicate with the City of Oslo control centre over a wireless wide-area network.
