The city of Elk Grove, California, completed its first installation of LED streetlights in October 2011. The project was approved by the Elk Grove city council in April 2011. The program involved both the purchase and installation of energy efficient streetlight fixtures and funding sources included the US Department of Energy’s Energy Efficiency and Conservation Block Grant (EECBG) program, municipal funds, and utility rebates. The EECBG award was for $166,442 and total project costs were $210,530.
The installation targeted the replacement of 163 existing 250 watt high pressure sodium (HPS) streetlights with LED streetlight fixtures on Laguna Boulevard and Elk Grove Boulevard. City engineers specified LED streetlight fixtures manufactured by BetaLED, a division of Cree/Ruud Lighting of Sturtevant, Wisconsin, for the project. According to city officials, the new fixtures have reduced energy consumption by approximately 50%. “The city is billed at a ‘per watt’ rate by the utility, so the lower wattage LED streetlights will result in immediate savings for the community,” said Jeff Werner, project manager for the city of Elk Grove and engineer with Willdan Engineering. One hundred fifty-one BetaLED streetlight fixtures with 80 LEDs were installed on Elk Grove roadways, and twelve BetaLED streetlight fixtures with 100 LEDs were installed at signalized intersections.
“Public feedback has been very positive,” said Werner. As part of the city’s sustainability initiatives, plans are being considered for additional streetlight replacement projects. There are approximately 47,000 streetlights in the Elk Grove municipal area, according to Werner. “The city is currently looking at and considering a variety of alternatives for replacing existing streetlights with LEDs, with a long term goal of eventually replacing all of the fixtures,” said Werner .
