The city council of Chattanooga, Tennessee, approved a measure to replace most of the city’s streetlights with energy efficient LED streetlight fixtures. The approved measure, which will be implemented in phases, will eventually result in the replacement of 27,000 streetlights. The first phase of the project, valued at about $6 million, will target approximately 5,200 existing fixtures for replacement. An exclusive contract for services was awarded to local manufacturer, Global Green Lighting.
“We installed about 500 streetlights in a pilot project and the results were outstanding,” said David Crockett, director of the office of sustainability for the city of Chattanooga. The pilot installation was funded by an award from the US Department of Energy’s Energy Efficiency and Conservation Block Grant (EECBG) program. “We installed a combination of LED roadway lighting, decorative LED lighting, and induction lighting. Our plan is to customize each location with the best source of illumination,” said Crockett. Initial results indicate that energy consumption was reduced by at least 65 percent in the locations where LED fixtures were installed. Additional calculations estimate that maintenance costs will be reduced by approximately 75 percent.
“The LED fixtures slated for our city’s project will all be individually controlled with dimming capabilities. This will enable us to turn fixtures on and off as needed, dim fixtures during certain times, and pin-point maintenance response. All of these features will save the city a significant amount over a fairly short period of time,” said Crockett. The city of Chattanooga is working in conjunction with the Tennessee Valley Authority and the Electric Power Board, the local municipal utility. Streetlight energy costs will be billed based on actual consumption. “We expect the total project to take about three years,” said Crockett.
