The Solar Energy Corp of India (SECI), they said, has additional/surplus solar power capacity of 14 GW in operation and under execution at various stages, and the same should be used by the railways.
SECI, the government agency that bids out solar projects, has already discovered a low tariff through competitive bids and railways could use this instead of introducing one more tender process through yet another central government entity, they said.
No developer has so far shown interest in the tender and made a bid, the sources said.
In April this year, REMCL had floated a tender for setting up 1 GW land based solar PV power plant in vacant railway land under tariff based competitive bidding.
Initially, the last date for putting in initial bids was June 30, but it was extended a few times, the latest being till November 25, 2020.
Bidders have been asked to quote a tariff they would charge for generating electricity using solar energy at projects of over 50 MW each.
REMCL was incorporated to manage energy management portfolio of Indian Railways which includes procurement of economical power through open access and harnessing green energy.
It has identified land in West Bengal (125 MW), Chhattisgarh (205 MW), Gujarat (226 MW), Odisha (59 MW), Madhya Pradesh (58 MW), Rajasthan (68 MW), Uttar Pradesh (20 MW), Haryana (19 MW), Assam (14 MW), Maharashtra (92 MW), Karnataka (20 MW), Jharkhand (13 MW), Telangana (7 MW) and Andhra Pradesh (18 MW).
