Background
The state government in its 2015-16 general budget tabled a proposal to replace conventional street lights consisting of non LED lamps with LED lamps to realise energy savings across all city corporations of the state.
In 2018 the government issued an order (UDD 550 PRJ 2017) to implement the project on PPP (Public private partnership) mode. The project aims to provide sustainable and energy efficient smart lighting in all city corporations.
Mysuru City Corporation is all set to implement the scheme with a centralised control and monitoring system. MCC has invited bids for the work. Time of completion would be 8 months from the date of award of work. The estimated budget is in excess of 100 crore.
Centralised Control and Monitoring System (CCMS)
The objective of deploying CCMS is to operate, control, monitor and rectify the integrated LEDs remotely via wireless communication. This would mean all the vital technical parameters/data of the LEDs can be accessed in one control room through software’s dashboard.
CCMS works on the node and hub model. A node here comprises LED luminaries connected to a controller and metering unit (CMU), a smart meter, which transmits all the collected data to the hub. Many such nodes representing various regions of the city communicate with the hub through cellular or RF networks.
The Hub houses a data centre with a control room which uses software to decode the data received from CMUs to interface with the operator.
Benefits of CCMS in street lighting context
- Real –time monitoring
- Geotagging of all luminaries
- Valuable Data collection
- Swift discovery of technical faults and rectification
- Scope for Automation
- Achieve higher Energy efficiency
Data is Gold!
Data collected can be analysed and effectively put to use to further achieve energy efficiency. The operator can remotely analyse faults, automate certain functions, check daily power consumption, raise notifications for errors, synchronise LEDs brightness with traffic patterns among other functionalities.
All luminaries however far they may be can be controlled from just a click away through the software dashboard by the operator. With data analysis more energy saving interventions can be proposed.
Mysuru city Corporation Savings Plan: Statistics
MCC is set to implement the scheme in all 65 wards of the city. Based on the category of roads, Indian standard for lighting of public thoroughfares has suggested the average LUX (luminance at road surface).
MCC has categorised the roads into A1, A2, B1 and B2 as per the IS 1944- 1970 code. The private operator can choose the relevant LED wattage to conform to the lighting standards.
As per MCC’s latest survey, there are 50639 conventional street lights, 9539 LED streetlights and 2752 energy meters.
MCC’s energy saving benchmark
| Parameter | Value |
| Present Energy consumption (kWh.) | 3,79,29,370 |
| Post LED implementation Energy Consumption (kWh.) | 1,56,36,643 |
| Energy Savings (kWh.) | 2,22,92,727 |
| Energy Savings (%.) | 58.77% |
MCC is aiming to achieve a guaranteed 58.77 % energy savings, hence, the operator has to achieve the guaranteed savings, failing which he shall be liable for penalty.
