The city of West Linn, Oregon, is participating in a conversion program to replace existing high pressure sodium (HPS) streetlights with LED streetlight fixtures. The program is being implemented through Portland General Electric’s (PGE) streetlight conversion project. The city of West Linn elected to participate in the voluntary program, and will replace approximately 950 streetlights with LED streetlight fixtures manufactured by Cree Lighting of Durham, North Carolina.
“We are converting about half of our streetlights which will result in significant savings for the city of West Linn,” said Lance Calvert, public works director for the city of West Linn. In addition to energy cost savings, the new streetlights will last significantly longer and provide improved illumination compared to existing HPS streetlights. Initial estimates show that the city will save about $20,000 annually with the new streetlights. “At this time we are only replacing cobrahead streetlights. Our residential fixtures are mostly decorative and are not currently targeted for replacement,” said Calvert. However, PGE is evaluating the potential to replace decorative streetlights, with LED fixtures, sometime in the future.
In February 2013, PGE started installations and established a model for streetlight conversions for cities in its service area. Utility customers elect to participate in the program, and then may choose LED fixtures from Cree Lighting or Leotek Electronics. PGE plans to install at least 26,000 streetlights within forty seven cities and five counties.
