Indira Gandhi International Airport (IGIA) in Delhi has become the first airport in India to run entirely on hydropower and solar power.
The airport will be able to offset two lakh tons of CO2 emissions per year with the switch to renewable energy to power its operations. This is a significant step toward achieving its goal of net-zero carbon emission by 2030.
Onsite solar plants meet around 6% of the airport’s electricity requirements. These include a 7.84 MW ground-mount solar power plant on the active airside and another 5.3 MW rooftop solar at the cargo terminals.
The 7.84 MW PV plant uses 27,800 modules and two types of seasonal tilts to ensure better system efficiency. An independent weather-monitoring system validates plant performance by monitoring and recording all parameters.
The airport meets the remaining 94% of its electricity requirements from hydropower. A Himachal Pradesh-based hydropower producer has signed a 25-year power purchase agreement to supply hydroelectricity for the airport until 2036.
