The plant, which is now capable of generating 7.84MW of 'green power', has been registered under the Clean Develelopment Mechanism of the United Nations Framework Convention on Climate Change (UNFCCC).
Delhi International Airport Limited (DIAL), the GMR led consortium responsible for operating the airport, claims that the power plant upgrade ensures that the gateway is "largely dependent on green power".
It says that the upgrade from 2.14MW to7.84MW was driven by the growing concerns about climate change and the rising need for green energy sources.
Commenting on the development, DIAL CEO, I Prabhakara Rao, enthuses: “At Delhi Airport we strongly believe that the collaborative approach is the key strategic element for combating climate change.
"As part of our extensive sustainability strategy, we have taken various efficiency measures at Delhi Airport.
"These include green infrastructure such as LEED-NC Gold Certification, Solar Power Generation, successful registration on energy efficiency with UNFCCC, Clean Development Mechanism, Water and Waste Management initiatives.
"The successful execution and expansion of solar power plant would not have been possible without the support of our concessioners and stakeholders.”
“Aligning with the vision of Hon’ble Prime Minister, Shri Narendra Modi, to harness solar energy to fight climate change, we aim to increase our solar power generation capacity to 20 MW by 2020."
