Data from street lighting pilots in India prove LEDs save money
- 08 July 2014
NEW DELHI: The Climate Group’s LED street lighting pilots are fueling the economic case for LED adoption in India, where latest data exposes the big energy and money savings being made by city leaders who have switched to the low carbon lighting.
Lighting accounts for nearly 6% of global CO2 greenhouse gas emissions, so transitioning to more energy efficient lighting is vital. Thankfully, low carbon LED (light-emitting diode) lighting is increasingly becoming an attractive street lighting solution for city managers.
As well as the low running costs and emissions that come with their high efficiency, LEDs also boast enhanced public safety and minimized light pollution; key reasons we called for all new street lighting to be LED (or as efficient as) by 2015, and all street lighting the same by 2020.
But barriers to large-scale acceptance of this super-efficient technology are rife. Attempting to tackle these barriers head on, The Climate Group conducted trials of LED street lamps in 10 big cities around the world in order to provide hard evidence of LEDs’ benefits – which we successfully delivered.
Evidence of LED success
Proving that LED products offer high quality light, durability, and significant electricity savings in the range of 50-70%, tangible results were published in our 2012 report Lighting the Clean Revolution and final city-specific reports are available here, along with this technical summary for lighting managers.
Following on from these reports, earlier this year we launched a new consultation process to accelerate LED street lighting around the globe – supported by our Lead Partner Philips Lighting – and continued working with cities to scale up their pilots.
Some of these cities are in India, where the British High Commission has supported our work in the states of West Bengal, Maharashtra and Orissa, to install LED projects and design supportive policy frameworks for scale-up.
Working with urban local bodies in the states’ cities of Haldia, Burdwan, Thane and Cuttack, we have prepared technical specifications and tender documents, and, after monitoring the lights’ performance in these cities, our results show LEDs demonstrate huge savings in electricity consumption and energy bills.
In Haldia, West Bengal, for example, 1,020 LEDs were installed by the Haldia Development Authority (HDA), delivering monthly savings of about 70,000 kWh of electricity and INR 500,000 in energy bills. Similarly, the Thane Municipal Corporation retrofitted 310 of its HPSVs with LEDs, resulting in electricity savings of 47%. You can dig into the data from these two city pilots below.
HALDIA LED PROJECT
The Climate Group facilitated the HDA in installing 1,020 LED street lights across the city of Haldia. First, a pilot project of 290 LED lights was installed on the HPL Link Road, and following the success of the pilot, HDA installed 730 more LED lights in the city.
The total investment for the project is about 40 million INR which is fully borne by HDA. In addition to electricity savings, HDA is also availing the reduced tariff for LEDs as required by WBSEDCL, saving energy costs substantially. The investment will be recovered in about six years and then HDA will be able to save the benefits of INR 500,000 a month for at least another five years, until the life of the LED is over. The electricity and monetary savings are given in Table 1 below.

THANE LED PROJECT
The Climate Group worked with the Thane Municipal Corporation (TMC) to install a pilot LED project to replace 310 street lights with LEDs. Other partners in the project are Bureau of Energy Efficiency (BEE) and the Maharashtra Energy Development Agency. The total investment budgeted is INR 80 Lakhs which is equally shared by TMC and BEE. The lights have been tested at a NABL accredited UL lab in Manesar, and measurements by TMC indicate 47% savings in electricity consumption. The savings from the lights are given in Table 2 below.

On top of the energy savings from installing LEDs, findings from the pilot projects indicate that the extra co-benefits of the low carbon lighting, including better quality lighting, lower maintenance costs, enhanced public safety, and improved user satisfaction, are all being met and exceeded.
Krishnan Pallassana, India Director, The Climate Group commented on the results: "Our LED pilots in Thane and Haldia present clear evidence that the low carbon technology makes sound business sense for any municipality to adopt LED street lighting. But they also illustrate an immense business case for corporates and financial institutions to invest in LED street lighting. It is a classic case of improved technology directly contributing to reduced fossil fuel consumption, while enhancing all-round efficiency. Like in Kolkata, these pilots' initiatives have the potential to catalyze an LED transformation in India, inspiring many other urban bodies. This is a win-win situation for all.”
