The county of Arlington, Virginia, has started a large-scale LED streetlight replacement program funded by the US Department of Energy’s Energy Efficiency and Conservation Block Grant (EECBG) program and local capital funds. The County will spend $1.5 million in 2010 to replace 1,800 existing streetlights with LED fixtures.

 

According to county officials, the long term goal is to replace all county owned streetlights with LED fixtures within the next six years. Currently the county owns 4,200 streetlights, most of which use high pressure sodium (HPS) technology. An additional estimated 12,000 streetlights are owned and maintained by Dominion Power. Arlington County is currently in discussions with Dominion Power about working together in the future to convert all 16,000 streetlights to LED technology over time.

 

An immediate gain realized by the county in the first phase of conversion is savings of nearly $100,000 in the first year by reducing energy consumption. The annual cost for powering Arlington’s streetlights is approximately $2 million per year. “We anticipate reducing our total streetlight energy costs by nearly 50%, and when we successfully convert all 16,000 streetlights, we will be saving about $1 million per year,” said Wayne Wentz, chief of transportation, engineering and operations for the county of Arlington.

 

Before choosing LED luminaires manufactured by Lumec for Arlington’s cobra head fixtures and Relume luminaires for the decorative streetlights, Wentz tested fixtures from five separate manufacturers. Arlington County has already replaced over four hundred HPS fixtures with LED streetlight fixtures. The existing 70 watt, 100 watt and 150 watt HPS fixtures have been replaced with equivalent LED fixtures, according to Wentz.

 

All purchasing has been completed for 2010, but county officials are developing purchasing plans for 2011 and 2012.
