These services include hospitals, railways including local metro transport, water supply systems and banks.
"We are looking at what is called islanding of areas to prevent disruption of essential services during any such untoward incident of a grid collapse," power minister Veerappa Moily told HT. "While the exact details are being worked out under the concept that is prevalent in most western countries, we will have dedicated power plants and feeder lines to keep emergency services running even when the grid trips."
An islanding system de-links a designated part of the network from the rest of the grid in the event of a major power failure. Officials said frequency sensors are installed, which disconnect the designated sector from the grid if the frequency dips below the designated level that trigger a grid collapse.
While stating that a final blueprint is under preparation, Moily said these dedicated plants "may not essentially be connected to the main grid."
But it remains to be seen if the plan will actually see the light of the day, experts are calling it a good strategy and face saver.
"For maintaining essential services as also sovereign functions of the government, having such a system for the NCR and major cities will be a good idea," former power secretary, Anil Razdan told HT.
