New Delhi: The Delhi Metro Rail Corporation (DMRC) is going to install a 3 MWp solar power plant on top of the elevated Metro stabling lines of the Kalindi Kunj depot which will cater to trains operating on the Janakpuri West – Botanical Garden corridor.
In view of the constraints in availability of adequate land for the Kalindi Kunj depot, Delhi Metro engineers decided to construct an elevated stabling shed to accommodate Metro trains for maintenance purposes. This in itself was a major engineering achievement since, for the first ever time anywhere in Delhi Metro, an elevated shed was being constructed to counter the paucity of space and taking this innovative approach further, DMRC has decided to utilise the available space of the roof area of the stabling shed for generation of solar power.
As per the plan, the solar plant will be set up on the frames of the stabling lines and will also serve the dual purpose of being the roof of the facility. A specialized agency was roped in to assess the feasibility of installing such a solar plant since Delhi Metro had not undertaken such a project before. Based on their report, a decision has been taken to install a 3 MWp plant there. The cost of installing this solar plant will be borne by the developer, as is the case with all DMRC plants, and Delhi Metro shall pay for the energy charges @ Rs. 5.4945 per unit, as levellised tariff for 25 years.
The work on the stabling shed will be completed in about six months and then the solar plant will be installed atop the shed. Delhi Metro has so far installed solar power facilities at three of its depots (Yamuna Bank, Ajronda and Mukundpur) and work is in progress towards installing more such plants in the other depots. Installation of solar plant of 880KWp at Kalindi Kunj depot has been completed and commissioning work is in progress. Presently, the largest solar power plant on an individual roof is the stabling shed of Yamuna Bank Depot with a capacity of 624 KWp.
Delhi Metro has so far commissioned 6.3 MWp of solar power plants across 21 locations in the Delhi Metro network. By March, 2017 DMRC will have commissioned solar power plants with capacity of about 20 MWp and by March, 2018, Delhi Metro will generate 31 MWp of solar power. As per its solar policy, DMRC plans to generate 50 MWp of solar power by the year 2021.
