Solar Potential for Delhi Metro Railway Corporations
The Delhi Metro Rail Corporation (DMRC) delivers public transport services to the population of Delhi. After completion of its phase II network constructions, DMRC will operate around 200 km of rail network, connecting more than 140 metro stations throughout the Delhi Metropolitan area.
ComSolar and DMRC have collaborated to study the potential and feasibility of utilising rooftop space available on DMRC properties, such as metro stations, for power generation through solar energy. Metro stations are ideal locations for PV installations in urban areas due to their large size, exposure and high visibility. According to DMRC suggestions, three sites (Indraprastha (IP) station, Yamuna yard and proposed Karkardooma station) were studied in greater detail to identify suitable pilot sites and business models for implementation and replication of the same across the entire future network of Delhi Metro.
It was found that the stations and yards of DMRC examined offer huge open spaces which can be utilised for solar PV systems with a capacity between 90 to 2.500 kWp, generating 400 to 10.000 kWh of electricity daily. The total potential for generation capacity of PV systems on all existing and planned DMRC sites (phase I, II and III completed) would be around 52 MW, equaling annual potential emissions savings of around 60 000 ton CO2 equivalent.
In order to tap this huge potential varied business models were examined for DMRC. The financially most attractive option would be for DMRC would be of feeding to the generated electricity to the gird, however Delhi Electricity Regulatory Commission (DERC) has not announced such scheme for public. Leasing of roof space, advertisement and e-vehicle charging were also identified as potential models. Another future option can evolves under the Renewable Energy Certificates mechanism (REC) which is a market-based instrument coming up to promote power from renewable energy sources.DMRC being one of the environemnt conciouse organisation has already taken up many initiatives for climate change mitigation and hence is ambitiuos about utilising maximum capacity of renewable to be installed at their sites to help the national goal for renewable energy supply and consumption.
