The city of Livermore, California, recently completed a large-scale retrofit of the city’s streetlights. This retrofit was preceded by a five year pilot and study of a variety of LED streetlight fixtures. The current project was implemented in partnership with Chevron Energy Solutions.
Prior to beginning the full retrofit, the city initiated a demonstration installation of LED streetlights along N. Livermore Avenue, Rhododendron Drive, and Lexington Way. This lighting demonstration was launched in part to inform the local citizens about the proposed project and allow for citizen input and feedback. According to city officials, “The project will help reduce operational costs,reach climate action plan goals, increase health and safety, help residents and businesses save money, and provide workforce development options.”
“We tested a variety of fixtures from different manufacturers over the last five years, and we ended up selecting fixtures from Bridgelux and Leotek Electronics for the retrofit project,” said Mohammad Pournia, engineering manager for the City of Livermore. According to Liza Wood of Chevron Energy Solutions, “After conducting a preliminary analysis of the different lighting fixtures on the market, several fixtures were installed as part of a demonstration project to compare the energy usage, lumen levels and light spread on the ground in both residential and industrial areas of the city.”
The city eventually selected and installed approximately 6,200 LED streetlight fixtures which resulted in the conversion of nearly all of the city’s existing high pressure sodium (HPS) streetlights. “The remaining streetlights in the city’s inventory are decorative and we plan to eventually replace those as well,” said Pournia.
The LED streetlight fixtures are expected to reduce energy consumption by around 46% translating to annual energy cost savings of $208,690. “The maintenance cost savings are expected to be substantial as well,” said Pournia.
Chevron Energy Solutions is currently working on LED streetlighting projects in the following California cities: Patterson, Waterford, Dublin, Concord, Union City, San Jose, Fremont, and Gonzalez.
