Bengaluru Airport Goes “Greener”- Targets Renewable Energy in a Big way

by Vijay Grover

Bangalore International Airport Limited (BIAL) goes “Greener” as it announced  the accomplishment of one of its ambitious goals of making theKempegowda International Airport, Bengaluru (BLR Airport) achieving a net energy neutral  status in the Financial Year 2020-21. As an outcome of energy conservation, BIAL says it  has been able to save nearly 22 lakh units of energy in the FY 2020-21. BIAL statement says it saved nearly 5 lakh units (KWH) from lighting, and has implemented chiller plant optimisation in Heating, Ventilation, and Air Conditioning (HVAC), which has resulted in saving of over 17 lakh units (KWH).

BLR Airport says in the current financial year it will be meeting 98% of its energy requirement of 20-21 through renewable sources. 

“As we expand our operations at BLR Airport, we aim to remain the flagbearer of sustainable operations. We have put in place various measures to reduce carbon footprint and protect our environment. Energy security is a very important aspect of our business as it is one of the key indicators to assess our sustainability levels,” said Mr. HariMarar, MD & CEO, BIAL.

BIAL’s Energy Management initiative is focused on achieving carbon neutrality through use of renewable, green and clean energy. BLR Airport has achieved energy neutral status since December 2020 through its onsite solar installations as well as Power Purchase Agreements (PPA) from solar and wind energy suppliers.

BIAL which has multiple measures in place to make BLR Airport environmentally efficient, with sustainability being the key pillar for all its operations to ensure integrity of economic viability, operational excellence and conservation of natural resources.

In an effort to become energy neutral , BLR Airport says it has increased the consumption from solar power to over 50 million units through on-site and off-site Power Purchase Agreements (PPA).

BLR Airport also makes optimal use of natural light with minimum reliance on artificial illumination during day time. BIAL’s other energy efficient initiatives include installation of solar street lighting; solar-powered security cabins; solar water heating system for the cafeterias.

The streetlights, perimeter lighting and airfield lights at BLR Airport have been converted to LED lighting. All this has further reduced the dependency on non-renewable energy.

In a bid to conserve consumption , the BLR airport converted 100 % of  existing 400 High Pressure Sodium Vapour Lamps (HPSV) on the Aircraft parking stands into energy-efficient LEDs to provide enhanced safety for pilots, greater visibility for ground staff and reduce energy consumption.

Along with this, the newly commissioned South Runway Airfield Ground Lighting is powered with LED lights, making it the first airfield in India to be fully powered with LED lighting system. The airport saysthat recently refurbished North Runway has also been powered with LED Airfield Ground Lighting.  The solar installations, deployed across 53,600 sq. m. on the Airside, will help BLR Airport save 37 lakh units of electricity annually, reducing its dependency on non-renewable sources of energy.
