The GMR Group-operated Delhi International Airport has become the first in Asia to host a mega solar power plant on its premises.
The airports of Kochi and Bhubaneswar have solar plants, but they are of 100 kW capacity each. Delhi is the first to have a megawatt scale, ground-mounted system.
As a thumb rule, at latitudes such as of Delhi, a 1 MW solar plant will generate 1.5 million units of electricity. Delhi International Airport Ltd will save at least Rs 2 per unit of electricity over what it pays now.
An expansion of the solar plant’s capacity is on the cards.
India has 136 airports, some of which are spread over vast pieces of land.
For example, the Hyderabad International Airport is spread over 5,400 acres while Chennai sits over 4,000 acres.
Large-scale solar plants are possible. Hyderabad, for instance, can house 25 MW.
The plant has been built for Delhi International Airport Ltd by German company called Enerparc, which specialises in airport solar projects among others. More info
