Railways goes solar to power city’s commute on local trains

The Railways invariably warn commuters to not travel on rooftop of trains as the live overhead wires supply 25,000 volts for the locomotives to run. Besides these live wires, roofs over the platforms would now become a medium of electricity as the authorities are placing solar panels on them. The Indian Railways is aiming to save electricity bills to the tune of Rs 41,000 crore between 2015 and 2025 under the ‘Mission 41K’ scheme.

These solar panels will have an installed capacity of 4,750kW or 4.7Mw of power. This amount of electricity is equivalent to the power used by floodlights at Wankhede stadium. The Western Railway (WR) has identified 23 locations on its Churchgate-Virar route, which also includes railway stations, for these panels. Sources in WR said there are seven railway stations (Mumbai Central, Lower Parel, Mahim, Khar Road, Andheri, Ram Mandir and Borivli) where solar panels would be fitted on the cover over platforms. The rest of the places include car sheds, rail administration and station buildings, workshops and yards.

Of the total 4,750kW electricity expected to be generated, the solar panels at railway stations will generate 2,185kW and the rest would be from the other structures mentioned above. “The work of completing installation of solar panels at some of these locations is in progress. At Mumbai Central, panels have been installed on the roof of the passenger reservation system building,” said a WR official.

It takes around 450-500Mw of electricity for running 240 rakes on both Western and Central Railway together in the city. “By installing solar panels, we expect to save around Rs 90,000 each day,” said a senior WR official.

The WR intends to use solar power to electrify tube lights, fans, lighting at food stalls, passenger announcement systems and other ancillaries at the station premises. Those solar panels fitted at station buildings and car sheds will help the railways to power the lights, fans, air-conditioners and other electric components found in a building.
