The 29.7km Noida Metro corridor will be India's greenest when it becomes operational a little over a year from now with a capacity to generate enough solar power to run not only all 21 stations but also its offices and train depot. The practices being followed are similar to those Delhi Metro is employing in Phase-3 and some of its existing stations, but Noida Metro will stand out as India's most environment-friendly Metro project because the entire corridor will homogenously use solar power, right from its head office to parking lots and footbridges. Noida Metro has set a target of generating 12MW of solar power daily, its managing director Santosh Yadav said on Tuesday. For that yield, it is installing solar panels on the rooftops of all stations, footbridges, its main office building, the depot and parking lot boundary walls.
