New Delhi : The Power Ministry Wednesday announced an ‘Islanding Scheme’ which will insulate essential services in various parts of the national capital from a severe power cut during a grid failure.
The scheme would become operational in January 2013.
Announcing the scheme, Power Minister M. Veerappa Moily said: “The islanding scheme for Delhi was presented by Delhi Transco Ltd. early hours today (Wednesday). In Kolkata, Mumbai and some other states, the islanding scheme is already operational. But it is not a system which is foolproof. This (Delhi proposal) can be a model for other states. Within three months the entire grid should be operational in Delhi.”
Delhi has created four islands to implement the scheme: Dadri-Jajjhar-Pragati, Bawana CCGT (Combined Cycle Gas Turbine), BTPS (Badarpur Thermal Power Station)-Pragati and Rithala CCGT. These units together would generate about 4,200 MW (mega watt) of power and would be capable of meeting about 3,400 MW of electricity demand during peak hours.
“It will be a unique and ideal scheme which will work on the ground and it will be reviewed every year,” Moily said.
The isolation mechanism would disconnect Delhi from the national grid during power disturbances. After the isolation, around 930 MW of demand from Delhi’s emergency power loads such as Delhi Metro, water treatment plant, the railways and hospitals would also be addressed.
Two successive grid failures of the northern grid blacked out almost entire north India July 30 and 31.
