ALPHARETTA, Ga. — The City of Alpharetta has begun a six-month long project to become more energy efficient.
On March 4, utility contractors working for Georgia Power started to convert streetlights throughout Alpharetta from high-pressure sodium lamps to LED lighting. Almost 3,000 streetlights will be converted.
The city has pursued the project to create a more proactive method for maintaining the city’s light fixtures and to help make the lighting more cost-effective while improving overall lighting, said Assistant City Administrator James Drinkard.
The new LED lights are designed to increase illumination along streets and sidewalks without causing nuisance to nearby properties. The change will also provide network lighting controls, which will allow better maintenance and repair scheduling, ultimately resulting in fewer non-working lights.
“Aside from the benefits noted as being our primary drivers, LED lighting has a considerably longer lifespan than the existing high-pressure sodium lamps,” Drinkard said. “That means fewer non-functioning lights and reduced service demands.”
Once replaced, the new LED lights are expected to save the city about $80,000 annually, he added.
Only pedestrian and streetlights on public streets will be converted. Lights on private property, private streets and on neighborhood amenity areas will not be affected. Any property owners or home owners associations interested in converting their lights during this project are encouraged to contact Georgia Power directly.
Crews will work on three zones, beginning with Zone 2, which encompasses a portion of northern Alpharetta, west of Ga. 400 and a portion of southern Alpharetta, between Ga. 400 and Ga. 120. After work in Zone 2 is complete, crews will move onto Zone 1, which surrounds Lake Windward, followed by Zone 3, which stretches from Rucker Road to Mayfield Road.
Crews working on the streetlights will be in vehicles marked as “Georgia Power Contractor” with identification available.
Conversions will begin with pedestrian light fixtures, also known as “post tops,” before moving on to larger streetlights, known as “cobras” or “mongooses.”
Most of the work will be done without any road or lane closures, but some brief lane closures may be necessary in a few cases, Drinkard said.
It’s more likely that some sidewalks will be temporarily blocked by workers’ equipment, he added.
The city is currently working with Sawnee EMC for a similar light conversion project. A schedule for that project has not be released.
