Indian Railways announce solar and wind power targets by 2021-22

Indian Railways is planning to source approximately 1,000 MW of solar power and nearly 200 MW of wind power by 2021-22 across zonal railways and production units. Indian Railways plans to install 500 MW of the 1 GW on the rooftop of railway buildings while the remaining 500 MW will be used to meet both traction and non-traction requirements. In a move to conserve energy, the South Central Railways has also installed solar panels at stations and service buildings across the zone.

Indian Railways plans to be a net-zero carbon emitter by 2030. To this end, it intends to increase the use of renewable energy in its operations. This presents a huge potential for renewable energy development, particularly solar and biofuel. While railway premises offer suitable sites for solar installations, the bulk use of diesel as fuel provides an opportunity for biodiesel. The Indian Railways Organisation for Alternative Fuel (IROAF) is the single-window entity for the work related to the use of alternative fuels in railways. The organisation’s objectives include switching to biodiesel and promoting the use of solar energy in rolling stock and mechanical assets.

While solar energy has been introduced in train coaches for lights, fans and charging points, most of the capacity addition has happened at railway workshops, stations and on office premises. In July 2018, the Hubballi workshop became the first location for Indian Railways where a 1 MW rooftop solar module was commissioned at a single location other than a station. Further, 2.204 MW of capacity has been set up in the Bilaspur zone, on the rooftops of zonal and division administrative offices, rest houses, and running rooms.
