In a cooperation between USAID, the United States agency for international development, and the Armenian government, a new lighting network has been installed. The infrastructure of the Armenian capital, Yerevan, is worn down and outdated and has not been upgraded for decades. This has had a very negative influence on the street light quality.
Previously, the street light was controlled in branches with only basic on/off functionalities. Each branch had to be inspected every day by technicians in order to avoid numerous outages. This procedure was not only labor-intensive, but also a very expensive practice.
Through USAID, a project involving 19 streets and 37 kilometers of line was launched in order to demonstrate the efficiency of such an installation. A centralized solution was chosen, allowing full control of the street lights from Yerevan’s lighting network center. This has enabled flexible lighting, allowing street light dimming at 1/3 and ½ of the full intensity. Daily inspections are no longer required and requests and inquiries from the central control point are immediately answered.
So far, the savings are expected to exceed the investments by 81%, allowing for a return-on-investment of approximately four years. There are plans to implement the system in the entire Armenian capital, supplying Yerevan residents with street light of significantly higher quality and reliability. The fact that it is cheaper and energy saving is an added bonus.
