The city of San Ramon, California, has awarded an LED streetlight replacement project to Republic ITS, an electrical contracting and transportation engineering firm with offices in the San Francisco Bay area. The $215,600 project, awarded after a competitive bid process, is funded by a grant from the US Department of Energy’s Energy Efficiency and Conservation Block Grant (EECBG) program. The award is locally administered by the California Energy Commission (CEC).
Republic ITS will be responsible for the purchase of LED streetlight fixtures, installation, public relations and EECBG reporting compliance.
San Ramon city officials anticipate replacing approximately six hundred high pressure sodium (HPS) fixtures with equal or lower wattage LED luminaires. Republic ITS will perform a full photometric study to assess appropriate wattage in each location, according to Jennifer Dye, contract and purchasing analyst for the city of San Ramon. The existing HPS streetlights are predominantly 70 watt, 100 watt and 150 watt fixtures and will be replaced with LED fixtures from BetaLED, a Wisconsin based manufacturer of LED roadway lighting.
“We expect to reduce our energy consumption by about fifty percent,” said Dye. Initial calculations indicate energy savings of about $390,000 over the life of the new LED fixtures. The city of San Ramon currently pays a flat rate per streetlight to energy supplier Pacific Gas and Electric (PG&E), but is in the midst of negotiating a revised tariff structure to reflect the reduced energy consumption of LED technology. “PG&E is offering a rebate to the city, and we plan on purchasing additional fixtures with those savings. Our city council is very supportive of the program,” said Dye. San Ramon owns and maintains about 3,700 streetlights.
