India’s Indira Gandhi International Airport in Delhi has increased the capacity of its on-site solar photovoltaic (PV) plant.

The plant, commissioned in 2014 at 2.14 MW, has now been expanded to 7.84 MW according to the airport’s owner, Delhi International Airport Ltd (DIAL), and stretches across 7 ha.

The expansion is expected to save around 5% per year on the airport’s power consumption, or Rs12 crore ($1.8 million) per year in energy costs.

DIAL CEO I Prabhakara Rao said the airport aims to increase the capacity of its solar plant to 20 MW by 2020, in line with India’s drive for more renewable power.

The plant’s non-reflective PV panels from Canadian Solar are designed to reduce glare so as not to interfere with airline operations.
