In order to deal with ongoing pollution problem in the city and conserve more energy, the Bangalore International Airport Limited (BIAL) has set a target of running Kempegowda International Airport (KIA) completely on solar power by 2020.
According to S Lakshminarayanan, Vice President (Engineering & Maintenance), BIAL, “Currently solar energy is harnessed from both roof-top and ground-mounted panels. We aim to make the airport 100% renewable-energy powered by 2020. We also plan to increase our consumption through on-site and off-site solar power purchase agreements.”
The power demand at KIA is 11MW per day currently and after the completion of the second terminal, airport authorities further estimate it to increase to about 20MW. The airport now generates 3.44MW from solar energy daily and the proposed capacity enhancement project will add another 8.35 MW in two phases, taking the total to about 12MW. While the 12MW would be from on-site energy generation, BIAL plans to source another 8MW of solar energy from off-site.
Lakshminarayanan also said that out of the 12 MW on-site energy generations, work has already started on installation of 3.35MW capacity plant. Another one with 5MW capacity is still in the planning stage.
He further said that continuous efforts are being taken up by BIAL, to implement the best energy conservation techniques. These include installation of LED lights, use of solar power, installation, modification and adoption of energy-efficient fittings and fixtures.
“To reduce energy consumption, we are also planning to convert all lighting to LED, except airfield ground lighting systems. As of now, all streetlights and 50% terminal lights are LED. Energy saved from use of LED lights is equivalent to 1.7 million units per year.” Added Lakshminarayanan.
Apart from this, BIAL is also working on the development of a solid waste management plant which will be become operational in 2019. This will make Bengaluru airport, the first in Asia to have an in-house solid waste management facility.
