The city of Tracy, California, is preparing to replace all city-owned streetlights with energy efficient LED roadway fixtures and seeks bids for a project involving 4,218 LED streetlight fixtures. The project, scheduled to begin in mid-2012, is focused on replacing over four thousand existing high pressure sodium (HPS) and mercury vapor streetlights with LED fixtures. The HPS streetlights targeted for replacement range from 70 watts to 250 watts. The mercury vapor streetlights targeted for replacement are 400 watt fixtures. Energy consumption will decrease by at least 50 percent.
The city council previously approved a Phase One retrofit program to replace streetlights owned by Pacific Gas and Electric (PG&E) with LED fixtures. The city tested and compared LED and induction technology at that time. Annual savings from replacing approximately one thousand streetlights, in older city neighborhoods, were estimated to be about $91,000. The project involved funding from the city’s equipment replacement fund and from a no-interest loan and rebates from PG&E.
The scope of work for the proposed installation includes the removal and disposal of the existing fixtures and installation of LED streetlight fixtures. Additionally, the bid document specifies that bids must be for LED streetlights manufactured by BetaLED, a division of Ruud Lighting, of Racine, Wisconsin, or Leotek Electronics, of Milpitas, California, or an approved equivalent. Final determination of approved equivalents will be made by city of Tracy staff. The city’s bid document provides detailed project specifications including photometric performance which includes a correlated color temperature (CCT) of 4,000 – 4,300 Kelvin ± 300K, a color rendering index (CRI) = 70, and a minimum five year warranty.
Completed bids must be submitted to the city of Tracy by March 15, 2012, at 2:00 p.m. The bid must be accompanied by a one time PG&E rebate calculation and a lifecycle energy cost savings analysis. Bids that are not submitted with this documentation will be rejected. The complete bid document can be found here.
