In a written reply to a question in Lok Sabha, Sinha said that Indian Railways proposes to harness solar energy by utilizing roof top space of railway stations, other railway buildings & land including through the PPP mode as per the feasibility, the modalities of which are being worked out.
However, solar power plants have been provided on top of two narrow gauge trains plying on Pathankot-Jogindernagar route in Kangra Valley section and Kalka-Shimla section on trial basis. On evaluation of trial and cost benefit analysis, further study of economic viability will be undertaken.
The estimated cost of about 8.8 MW-capacity for projects of providing solar panels under railway funding for works mentioned above is about Rs. 100 crore. The benefits of these projects are reliable power supply particularly at remote locations and saving in diesel due to reduced running of Diesel Generators.
