By next year, the Chennai Metro Rail Ltd., or the CRML, will go fully solar in phase one. In the next few months, 1 MW of solar power will be available. The CMRL will have another 8 MW of solar power later next year. Officials say that the plan is not just to make it self-sufficient but also feed the surplus power to the Tangedco grid.
According to reports, solar PV systems would be installed in elevated stations, depot and ancillary buildings of underground stations. An estimated 40,000 square metres of roof top area and about 20,000 sq. m. At the depots are available for the purpose. The CMRL has identified areas in stations along the Koyambedu-Alandur stretch that can be put to use.
Speaking about this, a CMRL official said, Chennai Metro Rail has identified spaces for solar generation in the next stretch between Little Mount and Chennai airport too. For exploring the potential to tap solar energy in the roof spaces of stations, Chennai Metro Rail has floated expression of interest where vendors can look at ways to implementing this project. The work on the first project of generating 1 MW power has already started and will be completed in a few months. The 8 MW project may take up to a year. But we are hoping complete it as soon as possible.
