Tiruppur Municipal Corporation having extent area of 159.34 sq km with length of streets as 1,332.55 km, contains 31,950 street lights. Energy saving technique has been implemented in this corporation under PPP mode since from 2014. This enables ESM equipment’s, 2,387 controllers through online Centralized Control Monitoring Station (CCMS) to perform ON and OFF operations, save energy and acquire real time data instantaneously. At present, there are only 618 non-burning street lights in the city (only 1.95%). The complaints received from on line portal, complaint register, toll free number and manual record. The non- burning defects rectified within stipulated time of 48 hours and feedback report send to public as a message from the portal.

ESM Equipment Installed
Tiruppur Municipal Corporation now contains 31,950 street lights. In which 15,074 are Fluorescent Tube Light (FTL) converted into LED lamps, 4,372 conventional lamps converted into Energy efficient lamps i.e. 250 High Pressure Sodium Vapour (HPSV) and High Pressure Mercury Vapour Lamp (HPMVL) Lamps and 5,392 LED Lamps provided under various schemes.
The project implemented to the entire city of Tiruppur City Municipal Corporation. All the components such as Service connections, a Voltage/Streetlight Controller with Energy meter is being installed as Energy Saving Measures. The Energy consumption recorded by the AMR equipment and the instantaneous real time data fetched from the ESM equipment connected with GSM technology and the performing the ON and OFF operation of the street lights with pre-set able time. The data collected includes Street Light Control (SLC) and Visible Light Communication (VLC) service connection ON and OFF, energy consumption, battery load, ward wise service connections, any error, etc. This data is visible in the Central Control & Monitoring Centre (CCMC) and can be monitored through www.tnsmartlights.com.
Key components of the system include:
Voltage/Street Light Controllers: State of the art GSM/ GPRS technology ON/OFF using contactors with GPS/Time basis lighting levels conforming to Indian standards reduces operational and maintenance cost, detection of energy theft or leakage, wireless ON/OFF control and scheduling ON/OFF.
Individual Lamp Monitoring Device: ILM is an efficient solution for real time monitoring of street lights on an individual basis for error free operation and improved energy savings. ILM system provides live status of the critical parameters through RF routing and helps extend the working life of the lamps.
Technology: Both GPRS & GSM based remote streetlight monitoring system with capacity for self-protection from short-voltage and anti-theft alert. • Automatic Meter reading (AMR) ensures the energy level on real time data.
Live Data Collection: Voltage, current, PF, Number of glowing hours, active & apparent power cumulative KWH.
Alert messages: High/Low voltage, Current, MCB trip, theft alerts, contactor failure, NO output supply and group of lights.
