Maximum City’s airport, minimum eco damage

Mumbai’s Mithi river, which is more popular for its stench rather than its water, will soon turn into a source of energy that’ll power the Chhatrapati Shivaji International Airport at Mumbai. A mesh of solar panels are being created to use the part of the Mithi river that flows through the airport as real estate to generate 600 KW of energy.

This initiative is not a one-off case. Mumbai International Airport Pvt Ltd, the body that runs the airport, is going all out to turn the airport carbon neutral by the end of 2017 and use every inch of space it has to generate more and more renewable energy.

Compared with its peer Delhi’s Indira Gandhi International Airport, the Chhatrapati Shivaji Airport in Mumbai is severely constrained by space. India’s second-busiest airport has an area of just 1,850 acres as against the more than 5,000 acres with Indira Gandhi International Airport.

That makes any sustainability effort a lot tougher. For starters, none of the solar panels can be installed on ground as there isn’t practically any space available. Rooftop panels are thus the only option. However, even there the angle of reflection needs to be adjusted carefully to avoid any inconvenience to the aircraft trying to land at the airport.

But amid landing and takeoffs of hundreds of flights each day, MIAL has been able to create space for 2 MW of solar panels atop old terminals of the airport. And the aim is to cross 7 MW capacity generation within two years.
