A Solar Solution on Indian Railways

The largest railway system in the world runs in India and it consumes a lot of energy to run it. Back when oil was more expensive they started looking into way to lower their fuel bill from using biofuel to solar. Today, they are running one solution that will save money in the first year of operations – putting solar panels on the roof of the train carriages. The panels will collect energy and store it in batteries instead of the current approach is using an additional diesel engine to power the carriages.

The rooftop solar system was developed by Noida-based Jakson Engineers, under the direction of the Indian Railways Organisation for Alternate Fuels (IROAF). “It is not an easy task to fit solar panels on the roof of train coaches that run at a speed of 80 km per hour. Our engineering skills were put to a real test during the execution of this rooftop solar project for Indian Railways,” Sundeep Gupta, vice-chairman and managing director of Jakson Engineers told the Business Standard newspaper. Established in 2008, the IROAF initially focused on bio-diesel and compressed natural gas (CNG) to help diversify Indian Railways’ fuel mix, before looking at solar.
Indian Railways has ambitious plans for solar. By 2020, the state-run transportation network plans to generate around 1,000 megawatts (MW) of solar power, which could be scaled up to 5,000 MW by 2025. These numbers are not only significant for the railways, given that it’ll help bring down the fuel bill, but will also impact India’s overall renewable energy goal of 175 gigawatt (1 GW = 1,000 MW) by 2022.
