Indira Gandhi International Airport's Terminal 3 Cuts Power Consumption by 57% Since 2010

Indira Gandhi International Airport's Terminal 3 has achieved a significant milestone in its sustainability efforts by reducing its power consumption per passenger by 57% from 2010 to 2023. The consumption has dropped from 5.18 kWh per passenger in 2010 to 2.21 kWh in 2023, according to Delhi International Airport Limited (DIAL).

This reduction is part of DIAL's broader goal to transform the airport into a net zero emission facility by 2030. The airport has implemented several green initiatives to achieve this reduction, including the use of state-of-the-art automation in complex systems such as Heating, Ventilation, and Air Conditioning (HVAC), Baggage Handling System (BHS), Information Technology (IT), and Airside Ground Lighting (AGL).

Other measures include the installation of LED lights and very high throughput (VHT) systems to maximize asset performance and optimize energy consumption through real-time monitoring and control. Additionally, the use of high solar reflective roof materials and double-glazed façades has contributed to the reduction in energy usage.

DIAL has also committed to using 100% renewable energy sources, such as solar and hydro power, to meet the airport's electricity needs. A 7.45 MW solar power plant on the airside is part of these efforts, making it the first such plant at an Indian airport.

The reduction in power consumption at Indira Gandhi International Airport's Terminal 3 has significant implications for the environment and sets a precedent for other airports to follow. The aviation industry's continued growth necessitates reducing energy consumption and emissions to mitigate the impact of climate change.

Looking ahead, DIAL plans to further reduce energy consumption by introducing new terminal infrastructure with a daylight harvesting concept, installing an advanced BHS system with integrated carts, and employing an advanced high-side chiller system. The airport also aims to use 100% LED lighting at terminals, city-side, and airfield ground lighting systems.

DIAL CEO Videh Kumar Jaipuriar emphasized the importance of these initiatives, stating, 'Our focus will be on implementing innovative solutions and leveraging best practices to achieve year-on-year reductions in specific energy consumption, all the while maintaining the highest standards of service quality and passenger comfort.'

The reduction in power consumption at Terminal 3 is a demonstration of DIAL's commitment to sustainability and environmental responsibility. The airport continues to implement these green initiatives, moving closer to its goal of becoming a net zero emission airport by 2030.
