Over an eight month period, the city of Walnut Creek, California, has installed one hundred eighty LED streetlight fixtures along Ignacio Valley Road, an arterial roadway. The success of the initiative has motivated city officials to consider additional LED streetlight installations throughout the city. The project was implemented in two phases.
The city of Walnut Creek participated in the Pacific Gas and Electric (PG&E) LED streetlight turnkey program which provides purchase, installation and maintenance of LED streetlight fixtures. The turnkey program requires that a municipality choose from a qualified list of manufacturers in order to receive the best price and highest possible rebate from PG&E. For the two phase Walnut Creek project, LED streetlights manufactured by BetaLED were chosen for installation.
“From a lighting perspective, it appears that more of the street is covered in light, and there is much better visibility on the pavement and sidewalks,” said Rafat Raie, city traffic engineer for the city of Walnut Creek. The streetlights originally installed on Ignacio Valley Road were 100 watt to 250 watt high pressure sodium (HPS) fixtures.
Funding for the first phase of the project came from the city’s general fund, while the second phase was funded by an award from the Department of Energy’s Energy Efficiency and Conservation Block Grant (EECBG) program.
Approximately six thousand streetlights currently light Walnut Creek, and the majority of these fixtures are owned by PG&E. About two thousand streetlights are owned by the city. According to Raie, “Walnut Creek has adopted a general policy to go in the direction of energy efficient lighting.” Discussions are already underway regarding the city’s next LED streetlight installation, which will again focus on arterial roadways, most likely involving California Boulevard and Mount Diablo Boulevard.
