Following the massive failure of the Northern Power grid on July 30 and July 31 -- which plunged Delhi and over 10 other states in darkness for over 14 hours across the two days -- the Delhi Metro Rail Corporation has decided to construct nine new power receiving sub-stations (RSS) and further strengthen four of its existing sub-stations for the upcoming Phase 3 Metro corridors.
The commute of thousands of commuters was disrupted on the morning on July 30 and the afternoon of July 31, due to the failures. The Northern Grid supplies power to the modern Delhi Metro rail system.
The four already operational power sub-stations of DMRC that will be augmented so that their feeds can be extended to the Phase 3 corridors as well are Jahangirpuri, Subhash Nagar, Botanical Garden and Kashmere Gate. The nine new sub stations will be at Yamuna Vihar, Vinod Nagar depot, INA, Dhaula Kuan, Mukundpur depot, Kalkaji, RK Puram, Palam and Faridabad.
Presently, Delhi Metro’s power requirements are regulated through 15 sub-stations, which are spread across different parts of the city and NCR. For Phase 3 of the metro, under which about 140 kilometres of Metro lines will be built in the National Capital Region, the approximate power requirement will be 150 MVA by 2016.
The presently operational 15 power sub-stations -- 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 Airport. These sub-stations presently receive 220 kV / 66 kV of power primarily from the grid sub-stations of BSES Rajdhani Power Limited (BRPL), BSES Yamuna Power Limited (BYPL), TATA Power Delhi Distribution Limited (TPDDL), New Delhi Municipal Council (NDMC), Uttar Pradesh Power Corporation Limited (UPPCL) and Haryana Vidyut Prasaran Nigam Limited (HVPNL).
The Delhi Metro normally operates over 2,700 trips a day, covering about 70,000 km and ferrying over a million passengers per week. The normal daily ridership on the Delhi Metro is over 19 lakh passengers per day.
