The report of the study conducted in collaboration with Bangalore Metro Rail Corporation Limited (BMRCL) from August last year to March 2026 has stated that both phases 2A and 2B of the nearly 60-km-long Blue Line can be powered by solar, while the land required would be already owned by BMRCL. The line will stretch from Central Silk Board to Kempegowda International Airport. This was done with the help of simulation reports from BMRCL, modelling solar energy panels, and other systems across 30 stations of the Blue Line, as well as the elevated viaduct and roofs of the train depots. According to the report, published earlier this month, the rooftops of the Blue Line metro stations alone cover an area of 1.09 lakh square metres, accommodating …
