New Delhi: 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.
"The islanding scheme for Delhi will be in place in three months," Union Power Minister Veerappa Moily said at a joint press meet with Delhi Chief Minister Sheila Dikshit here on Wednesday.
The islanding scheme comes against the backdrop of massive Northern Grid failure in July this year that affected power supplies to many states and regions, including Delhi.
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 -- 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.
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," he noted.
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.
