India’s largest subway system is set up fully switch to solar power from next year with an aim to reduce its growing carbon footprint.
Delhi Metro Rail Corporation chief Mangu Singh told reporters that the subway system shall fully shift to solar power to run trains and support infrastructure, like lighting at stations, from next year.
DMRC shall maintain backup power systems in case of any eventuality. There have been no reports so far to indicate that the the DMRC shall use battery storage systems as well.
Currently, DMRC has a peak demand of 150 megawatts which is expected to increase to 250 megawatts on network expansion. DMRC has signed an agreement with Rewa solar power park, proposed for installation in the state of Madhya Pradesh, to acquire 250 megawatts electricity. Power from that project should start flowing from next year. The solar power park is stalled to have a total installed capacity of 750 megawatts.
Delhi Metro already operates several rooftop solar power systems at many of its stations. The rooftop system fulfil the electricity needs of the stations. The Corporation is set to expand this network of rooftop solar power systems and targets to have installed rooftop solar capacity of 50 megawatts by 2020.
Since its inception Delhi Metro has taken several measures to reduce its carbon footprint and maintain sustainability. Coaches used by Delhi Metro have regenerative braking systems installed.
