Indian Prime Minister Narendra Modi is set to open Terminal 2 of Kempegowda International Airport (BLR), Bengaluru, in the state of Karnataka this week.

According to officials, the new terminal has been built with an investment of about $612m (Rs50bn).

The new terminal will help the airport double its passenger accommodation capacity besides increasing the number of counters for check-in and immigration services.

With the launch of the new terminal, the airport can annually manage between 50 and 60 million passengers, up from the current capacity of 25 million.

The officials were quoted by various publications as saying that “Terminal 2 is designed as a tribute to the garden city of Bengaluru and the passenger experience is meant to be a ‘walk in the garden’.”

The new terminal features more than 10,000m² of green walls, as well as hanging gardens and outdoor gardens.

Using indigenous technology, these gardens have been produced in India.

“Based on the sustainability initiatives, Terminal 2 will be the largest terminal in the world to be pre-certified platinum rating by US GBC (green building council) prior to commencing operations,” the government said in its press statement.

As part of the sustainability efforts, the airport already uses 100% renewable energy across the site.

Last year in September, Plaza Premium Group (PPG ) was chosen by the Bangalore International Airport Limited (Bial ) to manage passenger services at Kempegowda Airport.
