In order to take control of situations that Delhi faced in July when two major grid disturbances disrupted the normal life in the national capital for two consecutive days, union power minister Veerappa Moily on Wednesday announced the ‘islanding scheme for Delhi during grid disturbances’.
Delhi chief minister, Sheila Dikshit, and Moily in a press conference on Wednesday said that union power ministry has completed all formalities for Islanding Delhi during grid disturbances.
Officials said that the task which was to be completed within three months have been accomplished much earlier. The Delhi government will implement the islanding facility for power supplies in three months, a move aimed at preventing electricity supply disruptions for essential services in case of grid disturbances.
Once this facility is in place, Delhi would be able to ensure power supplies for essential services such as Delhi Metro Rail, water treatment, hospitals, airport, VVIP areas and Indian Railways even if there are Northern Grid problems.
Dikshit said the scheme would be operational by January next year, ahead of the schedule whereby the same was to be ready by middle of 2013.
According to Moily, the islanding facility for Delhi is being set up at a cost of Rs 25 crore and it would have a capacity of up to 3,400 MW.
Currently, the essential electricity load spread across various distribution companies in Delhi is 930 MW.
Already, cities such as Mumbai and Kolkata have islanding schemes.
As per the scheme for Delhi, fall of grid frequency to 47.9 Hz, the normal frequency for electricity transmission would be considered as an indicator to initiate islanding facility.
The electricity for this scheme would be provided by four islands including Dadri-Jajjhar-Pragati [2,315 MW], Bawana CCGT [600 MW], BTPS-Pragati [500 MW] and Rithala CCGT [20 MW].
Four islands for supply of electricity have been envisaged due to certain network issues: Dadri-Jajjhar-Pragati, Bawana CCGT [Combined Cycle Gas Turbine], BTPS [Badarpur Thermal Power Station]-Pragati and Rithala CCGT.
Delhi State Load Despatch Centre [SLDC] would have the overall responsibility of operating the island system. With regard to the scheme, Dikshit said there would be continuous upgradations.
Union power secretary P Uma Shankar said that more states have proposed to set up islanding facilities. ‘Uttar Pradesh, Punjab, Haryana and Jammu & Kashmir have come up with plans for islanding facilities.These will be finalised in the next few months,’ said Shankar.
In August, during a meeting of union power minister and chief ministers/power ministers of northern states, it was decided that they would prepare their islanding schemes. The enquiry panel, that looked into the reasons for the recent collapse of power grids, had also suggested the creation of electricity islands.
‘The islanding scheme for Delhi was presented by Delhi Transco 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,’ said Moily.
These units together would generate about 4,200 MW of power and would be capable of meeting about 3,400 MW of electricity demand during peak hours.
