Solar Plant for Bangalore International Airport

The solar journey of Kempegowda
International Airport (BIAL)


Taking a step forward as a part of PMO’s 100 GWp solar target by 2022, Kempegowda International Airport, Bengaluru (also known as Bengaluru International Airport Ltd – BIAL) became the first airport in Karnataka to go solar. ‘Sustainable progress’ is the thought that sets the direction for the solar airport. As a role model for sustainable progress, the journey has been marked by measurable achievements and inspiring stories. One such story includes BIAL adopting solar power. It marked a completely new journey for BIAL as it has gone green, without any capital expenditure, while saving electricity costs at the same time.
BIAL was actively looking to partner with a solar developer to meet its objective of building a sustainable airport. Around the same time, Solar Energy Corporation of India (SECI) empanelled CleanMax, to help develop rooftop solar power plants for government installations. SECI referred CleanMax for its superior quality and quick installations timelines, which laid the foundation of a bright journey. CleanMax has developed the 500 kWp on-site plant at the airport, as a part of the commitment and arrangement with SECI.
Airport being a sensitive area (security-wise and constant mass movement), required very strict regulations to be followed while working. It posed challenges for CleanMax Engineers in terms of limited access to buildings, the upper cap on the number of people working on site, restricted movement of material within the premises etc. CleanMax overcame these challenges with highly efficient workers, who completed the construction within 2 months of signing the Power Purchase Agreement (PPA) to successfully build a solar powered airport
