Cochin International Airport Limited holds the distinction of being India's first airport constructed under a Public-Private Partnership (PPP) model. Opened to commercial operations on June 10, 1999, CIAL has evolved into a regional aviation hub serving Kerala's strategic position in global trade routes. Located in Nedumbassery, approximately 28 kilometers northeast of Kochi city, the airport currently ranks as Kerala's busiest and India's fourth-largest airport by passenger volume. A remarkable achievement distinguishes CIAL globally: it became the world's first fully solar-powered airport, operating a 12 MW solar power plant that generates net positive energy. This sustainability milestone has earned CIAL numerous international awards and recognition as a leader in green aviation practices. The airport handled 11.14 million passengers during FY 2024-25, representing 7.5% year-over-year growth, reflecting strong recovery and expansion in both domestic and international segments. Ownership structure comprises the Government of Kerala (33.36%), Indian government companies (8.74%), foreign investors (5.42%), Indian corporates (8.57%), scheduled commercial banks (5.91%), and over 10,000 individual investors from 29 countries, primarily non-resident Indians. Trading at ₹442.00 and noted as a top gainer, CIAL represents a unique investment combining infrastructure stability, sustainability leadership, and strong operational growth momentum.
