Airports need lots of flat, open, unobstructed land surrounding them. Why not fill that open space with solar panels? Several large airports have done just that.
This week, Cochin International Airport Limited in Kochi, Kerala
(India) inaugurated a 50 acre, 12 MW solar PV plant, making it the first
airport in the world to offset 100% of its usage through the use of
solar. The airport also has another 1 MW solar PV plant in addition to a
smaller grid-connected 100 kW rooftop system, both of which were
installed two years ago. Also in India, the Indira Gandhi International
Airport near Delhi installed a 2.14 MW plant last year.
According to solarlove.org:
“The Airport Authority of India (AAI), which operates 125 airports
across the country, including the Cochin and Kolkata airports, has
decided to build solar power plants at about 30 of its airports.
AAI has plans to install 50 MW capacity plants in the first phase (by
2016), which would be enhanced to 150 MW over a period of time.
