Delhi Metro Rail Corporation (DMRC) Ltd. is installing Solar Panels in its station buildings, depots, colonies, parking areas and RSS. As per DMRC Solar Policy, DMRC has to increase the share of renewable energy by 20 MW and 50 MW upto 2017 & 2021 respectively.
In this regard, on 17th September 2013, the Delhi Metro Rail Corporation (DMRC) and the Solar Energy Corporation of India (SECI) signed a Memorandum of Understanding (MoU) to carry out projects for the production of renewable solar power in the Delhi Metro premises. As per the MoU, both the organizations will collaborate for the development of Solar PV (Photovoltaic) Projects (ground mounted, rooftop and other possible modes) at identified DMRC Sites for the production of solar energy.
In Feb 2014, Power Purchase Agreement was signed with SEI Superior Pvt. Ltd. (subsidiary of Sun Edison) for Dwarka Sector – 21 Station. The first solar module of Delhi Metro’s inaugural ‘Roof Top Solar Power Plant’ of 501 kWp capacity was installed at the Dwarka Sector 21 Metro station which was started on 27th June 2014. With the beginning of its solar power production, the Delhi Metro Rail Corporation (DMRC) has become the first ever Metro system in the country to install ‘Roof Top Solar Power Plants’ at its Metro stations.
In order to mitigate the risk of extent of power generated by Solar radiation, DMRC preferred RESCO (Renewable Energy Service Company) model. Under this model, project cost is to be borne by the Developer and the developer will enter into a PPA (Power Purchase Agreement) for 25 years with DMRC at a mutually agreed tariff. Also, there is no capital expenditure by DMRC in this model.
As on 30th September’16, DMRC has already commissioned 7.22 MWp solar plants in its premises. For around 4.5 MWp work is under progress and for another 20 MWp, PPA has been signed. These solar projects will reduce large amount of Greenhouse Gas emissions by replacing carbon intensive grid power with renewable energy. The power generated by these plants will be used for DMRC’s operational requirements, which include station lighting and other loads.
