Indian Railways to procure power from wind-solar hybrid projects

The Railway Energy Management Company Limited (REMCL), a joint venture between the Indian Railways and RITES Limited, has issued a request for selection to procure power from wind-solar hybrid projects. The wind-solar hybrid projects will be set up on a build-own-operate basis. The maximum tariff payable has been fixed at Rs 2.93 per kWh for the entire power purchase agreement (PPA) term of 25 years. The timeline for commissioning the entire capacity has been set at 27 months from the effective date of the PPA.

In October 2019, Railway Energy Management Company Limited issued a request for qualification to set up approximately 32.56 MW of rooftop solar systems at various railway establishments and stations across India. The rooftop solar systems will be set without any subsidy or viability gap funding support from the Ministry of New and Renewable Energy or the Indian Railways.

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.

Indian Railways overall experience with renewables has been positive so far. However, the maintenance of solar panels installed over a large area has been a challenge for the utility. To this end, the PPP model is being adopted for renewable energy development. The PPP model ensures the implementation of the latest technologies such as compact substations.

To achieve 100 per cent renewable energy use by 2030, the organisation needs to ensure that even smaller stations attract developer interest. It also needs to fulfil its 8 per cent renewable purchase obligation, overcome interstate transmission challenges through open access, implement net metering and attain an optimum energy mix of wind and solar. However, there are several other challenges that need to be addressed.
