Summary: | Vizag at night is illuminated with
91,000 streetlights that are owned by GVMC. Before Cyclone
Hudhud, most of the streetlights used high-pressure
sodium-vapor (HPS) or tubular fluorescent lamp (TFLs)
technologies. Within GVMC’s jurisdiction, there are 8 zones
made up of 72 wards and approximately 4,000 manual points to
switch the streetlights on and off. Maintenance was
outsourced, with operation and replacement of streetlights
handled through a dedicated customer care service center.
Registered complaints were forwarded to the assistant
engineer of the respective ward or zone and generally
addressed within 72 hours. The replacement of HPS and TFL
lamps with LED lamps resulted in energy savings of more than
50 percent, along with improvements in road illumination
levels. In addition, a central control and monitoring system
(CCMS) has been installed that controls the LED streetlights
remotely, reduces the time for fault detection, and provides
better control of switching and dimming to reduce energy
consumption. The CCMS in Vizag is a ‘smart’ system, with
information on each light available to be viewed and
reported easily via a web-based tool. Vizag also uses the
CCMS to measure energy savings, providing the municipality
with much more information than they had previously about
the energy consumption of their streetlights. |
