Street Lighting National programme (SLNP) illuminated 50,000 KM of Indian roads
Street Lighting National programme (SLNP) has illuminated 50,000 KM of Indian roads with installation of 30 lakh LED street lights across the country. With this milestone Energy Efficiency Services Limited, a government of India company under the administration of Ministry of Power, has become the world’s largest street light management company.
Street Lighting National Programme – Features
The main objective is to promote efficient lighting, enhance awareness on using efficient equipment which reduce electricity bills and help preserve environment
The installation of 30 lakh LED street lights has resulted in 39 crore kWh of annual energy savings, avoided capacity of over 104.19 MW to the Urban Local Bodies (ULBs).
The Street Lighting Programme has also helped in reduction of 3.29 lakh tonnes of CO2 annually.
Under Street Light National Programme (SLNP), replacement of 3.5 crore conventional street light will result in saving of 9,000 million units annually. Total cost savings of municipalities every year will be Rs 5,500 crore.
Energy Efficiency Services Limited (EESL) has been designated as the implementing agency. The initiative is part of the Government’s efforts to spread the message of energy efficiency in the country.
Under the Street Lighting National Programme SLNP, Rajasthan is leading the country with an installation of 7.85 lakh LED street lights followed by Andhra Pradesh and Gujarat with 6.03 lakhs and 5.4 lakhs respectively.
EESL is retrofitting 15,000 conventional lights with LED street lights every day.

EESL Service Model
EESL replaces the conventional street lights with LEDs at its own costs and consequent reduction in energy and maintenance cost of the municipality is used to repay EESL over a period of time.
The contracts that EESL enters into with Municipalities are typically of 7 years duration where it not only guarantees a minimum energy saving but also provides free replacements and maintenance of lights at no additional costs to the municipalities.
The service model enables the municipalities to go in for the state of the art street light with no upfront capital cost and repayments to EESL are within the present level of expenditure.
Thus there is no additional revenue expenditure required to be incurred by the municipality for change over to smart and energy efficient LED street lights.
Lumen intensity of LED vs incandescent bulb –
LEDs have no gases, filaments or any moving parts to fatigue. A 7W LED procured under DELP gives the same and in most cases better lumen intensity and brightness than a 60W Incandescent Lamp.
The lumen output of a 60 Watt incandescent bulb is 450 lumens. Whereas, the lumen output of a 7 watt LED bulb, offered as part of the DELP scheme, is 600 lumens.
The proportion of lumens that falls in an area from an LED light source is greater than that of a conventional light source.
|Advantages of LED|
|Annual cost saving in the electricity bill (per bulb)||INR 160-400||INR 85.5||NIL|
|Life expectancy (Hrs)||25,000||8,000||1,200|
|Free of cost Warranty||3 Years||1 Year||NIL|
