NEW DELHI: DMRC is going to construct nine power sub-stations and strengthen four existing ones for the underconstruction Phase III of the Metro network. The new sub-stations will come up at Yamuna Vihar, Vinod Nagar depot, INA, Dhaula Kuan, Mukundpur depot, Kalkaji, RK Puram, Palam and Faridabad.

Phase III, which will cover 103km, will have two new corridors — Mukundpur to Shiv Vihar and Janakpuri (west) to Botanical Garden. The nine new sub-stations, along with the existing four, will also power the Badarpur-YMCA Chowk corridor. Auxiliary power at 33kV and traction power at 25kV will be supplied from the new sub-stations to the Phase III stations.

"The four operational power sub-stations of Delhi Metro Rail Corporation (DMRC) will be augmented so that their feeds can be extended to the Phase III corridors as well. These operational sub-stations are Jahangirpuri, Subhash Nagar, Botanical Garden and Kashmere Gate," said the spokesperson.

Currently, the Metro's power requirements are regulated through 15 sub-stations spread across different parts of the city and the national capital region. For Phase III, under which about 140km of Delhi Metro lines will be built in NCR, the approximate power requirement will be 150MVA by 2016, added Metro officials.

The 15 sub-stations are at Kashmere Gate, Rithala, Jahangirpuri, New Delhi, Indraprastha, Dwarka, Subhash Nagar, Mundka, Chhattarpur, Sarita Vihar, Botanical Garden, Sushant Lok, Park Street (two sub-stations) and IGI.

The Phase III construction has started with the extension of the Badarpur-Central Secretariat line to Kashmere Gate through Janpath, ITO, Jama Masjid and Red Fort. The same line will also be extended from Badapur to the interiors of Faridabad.
