Spearheading the country’s street lighting national programme, the SLNP executed by EESL has set a target of retrofitting 14 million street lights by 2019 with energy efficient LED bulbs.
The energy savings for a specific project depends on various factors, including existing lighting technology, new lighting technology, control strategies, and charging the illumination level during retrofits. Holding true to EESL’s vision of heralding future-ready technology that boost efficiency and profit rates, EESL’s LED lamps have a Central Control Monitoring System (CCMS), which allows remote monitoring and operation of the installed street lights.
This ensures that street lights are automatically switched on once the sun sets, and switched off after dawn. The system also sends alerts for each light that needs attention, to reduce failure and the need for sudden repair. Therefore, the avoided capacity of electricity can be ascertained from the reduced consumption of electricity. The system also helps note the exact consumption of energy, which is used to define the cost to be paid.
Hon’ble Prime Minister, on 5th January, 2015 launched Street Lighting National Program (SLNP) to replace conventional street lights with smart and energy efficient LED street lights across India.
EESL replaces the conventional street lights with LEDs at its own costs (without any need for municipalities to invest) and the 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 (of-typically 50%) but also provides free replacements and maintenance of lights at no additional cost to the municipality.
Till date, EESL has installed over 1.14 Crore LED street lights in ULBs and Gram Panchayats across India. This has resulted in estimated energy savings of 7.72 billion kWh per year with avoided peak demand of 1,286 MW, GHG emission reduction of 5.32 million t CO2 per year and estimated annual monetary savings of INR 5,395 crore in electricity bills of municipalities.
Under SLNP, 1576 Urban Local Bodies (ULBs) have been enrolled, out of these ULBs, work has been completed in 1060 ULBs.
EESL is also implementing LED Street lighting projects in Gram Panchayats on the same service model as the SLNP for municipalities with the objective to promote the use of efficient lighting in rural areas. So far, EESL has installed 26 lakh LED street lights in rural areas of Andhra Pradesh, Jharkhand, Goa and Telangana.
The LED street lights are installed after a detailed survey of the existing infrastructure is undertaken. The survey inter-alia looks at the infrastructure gaps, verification of inventory and mapping locations for setting up CCMS (Centralized Control and Monitoring System)
