Delhi Metro has so far installed solar power facilities at Yamuna Bank, Ajronda and Mukundpur.
Delhi Metro will install a 3 MWp solar power plant atop an elevated stabling line of Kalindi Kunj depot, the first-ever such shed being built in the DMRC network.
"The work on the stabling shed will be completed in about six months and then the solar plant will be installed atop the shed," the DMRC said on Sunday.
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.
The plant will cater to trains operating on the Janakpuri West-Botanical Garden corridor, construction of which is underway.
"A specialised 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 at the rate of Rs 5.4945 per unit, as levellised tariff for 25 years," it said in a statement.
As per the plan, the 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.
Presently, the largest solar power plant on an individual roof is the stabling shed of Yamuna Bank Depot with a capacity of 624 KWp, DMRC said.
Delhi Metro has so far commissioned 6.3 MWp of solar power plants across 21 locations in its network.
By March next year, it would have commissioned solar power plants with capacity of about 20 MWp and by March 2018, it will generate 31 MWp of solar power, it said.
As per its solar policy, DMRC plans to generate 50 MWp of solar power by the year 2021.
On the Kalindi Kunj depot's construction, DMRC said it was a "major engineering achievement" as for the first-time ever, anywhere in Delhi Metro, an elevated shed was being built due to paucity of space.
