Told to cut power to prevent grid collapse
States to stop overdrawing from Northern Grid
NEW DELHI: Power distribution companies in the Capital now have an additional role to play: they will be responsible for ensuring that Delhi adheres to the grid code and does not overdraw electricity from the Northern Grid.
Taking note of rampant overdrawing of electricity from the Northern Grid in the past few days, States that are members of the Northern Region Power Committee (NRPC) have decided that distribution companies will ensure that grid discipline is maintained and load-shedding is carried out to save the grid from collapse.
At a meeting of the Committee on Friday, the States decided to implement self-regulation and desist from drawing more electricity than their allocated share.
“At a meeting of the technical coordination committee and the board meeting of NRPC it was decided that all States will stop overdrawing power from the Northern Grid when the frequency is below 49 Hz. with immediate effect,” said a senior Power Department official.
The NRPC members have also decided that States where the transmission and distribution are managed by separate entities like in the case of Delhi, it will be the distribution companies that will be in charge of carrying out load-shedding to prevent any damage to the equipment when under-frequency is reported.
“Only essential services like water works, hospitals and airports need to be insulated from power cuts.
The discoms are responsible for managing their own load as per the directives of the Central Electricity Authority and in accordance with the Electricity Act. They will have to carry out load-shedding depending on their own arrangements and the actual drawing of energy,” the official said.
Delhi Transco’s under-frequency relays will be used as a back-up and the discoms will have to ensure the operation of under-frequency relays in their own areas of operation.
Meanwhile, the power situation in the Capital on Friday was marginally better. Under-frequency was recorded 47 times in the Northern Grid and the city’s power generations stood at 1,275 MW.
The maximum load on the system was 3,129 MW at 3- 29 p.m. and rotational load-shedding was carried out across the city.
Delhi also faced a shortfall on account of forced outages at some of its plants.
One unit each at the Dadri and Gas Turbine stations continued to remain out of order.
Apart from Delhi, the States that had to overdraw power included Uttar Pradesh, Jammu and Kashmir, Punjab and Haryana.
