According to reports, to safeguard Delhi and its surrounding areas from electricity supply disruption during grid failure, the Government on Wednesday announced ‘Islanding Scheme’.
The scheme would be fully operational by January 2013, Power Minister Veerappa Moily told mediapersons.
Delhi has created four islands to implement the scheme namely Dadri-Jajjhar-Pragati; Bawana CCGT; BTPS-Pragati and Rithala CCGT. These units would together generate about 4,200 MW and would be capable of meeting about 3,400 MW of load, during peak hours.
The total investment in the project is Rs 25 crore. The Delhi scheme is different from the existing ones in Kolkata and Mumbai. This is because several inter-state electricity transmission lines are routed via Delhi, said A S Bakshi, Chairperson of Central Electricity Authority.
This mechanism would disconnect Delhi from the national grid during disturbances prohibiting power failure in the city. After isolation, the power generated within Delhi would be supplies to meet the demand within the State.
For instance, incidences like the grid failures that occurred in July that affected more than half of the country would not affect electricity supplies in Delhi.
Delhi’s emergency loads such as Metro, water treatment, Indian Railways and hospitals with 930 MW demand would also addressed.
A few more states such as Haryana, Punjab, Uttar Pradesh and Jammu and Kashmir have come up with a proposal to implement islanding schemes in their respective states, said Power Secretary P. Umashakar.
