Monitoring Report
A major power breakdown — trigged by frequency variation in the national grid — took place across Pakistan on Monday, leaving large swathes of the country, including Islamabad, Karachi and Lahore, deprived of electricity.
According to the Ministry of Energy, the system of frequency of the national grid went down at 7:34am today resulting in a widespread breakdown in the system.
“System maintenance work is progressing rapidly,” it tweeted.
In an interview with Geo News, Energy Minister Khurram Dastgir said that the breakdown was not “major”.
“In winter, the demand for electricity reduces nationwide, hence, as an economic measure, we temporarily close down our power generation systems at night.
“However, when the systems were turned on in the morning today, frequency variation and voltage fluctuation was observed in the south of the country […] somewhere between Dadu and Jamshoro […] because of which power generating units shut down one by one,” he explained.
Dastagir went on to say that the restoration of grid stations in Peshawar and Islamabad had begun. “I can assure you that power will be fully restored across the country within the next 12 hours,” he added.
Talking about Karachi, the minister said: “We provide K-Electric about 1,000-1,100 megawatts routinely […] power in the city will be restored within a few hours.”
In October last year, Pakistan witnessed a 12-hour breakdown after a disturbance was reported in two 500kV lines in the south of Karachi. The electricity blackout took out approximately 8,000MW from the system.
KE assessing situation in Karachi
In Karachi, power outages were reported in Malir, Landhi, Gulistan-i-Johar, Akhter Colony, II Chundrigar Road, New Karachi, Gulshan, Ibrahim Haideri and Korangi.
In a tweet, K-Electric spokesperson Imran Rana confirmed that the country-wide breakdown had affected the power supply in Karachi as well.
He said KE teams were assessing the situation and the process for the restoration of electricity had been initiated.
Later, Rana said that the company’s first priority was to restore power to strategic facilities including hospitals, airports, etc.
Three transmission lines trip in Balochistan
Meanwhile, Quetta Electric Supply Company spokesperson Muhammad Afzal told Dawn.com that three transmission lines in the province — 220kV Uch-Sibbi, 220kV Dadu-Khuzdar and 220kV Dera Murad Jamali — had tripped.
“This has resulted in a massive power outage across Balochistan,” he said.
The affected cities include Quetta, Pishin, Qilla Abdullah, Chaman, Loralai Zhob, Qilla Saifulllah, Mastung, Sibbi, Ziarat, Kalat and Khuzdar.
Afzal added that restoration efforts were underway by the National Transmission and Despatch Company (NTDC).
117 grid stations affected in Islamabad
Meanwhile, in Islamabad, nearly 117 grid stations were affected due to the breakdown, the spokesperson of the Islamabad Electric Supply Company said.
“System maintenance is being directly monitored from the central control room and power is being restored in a phased manner to protect the system from damages,” he told Dawn.com.
The spokesperson elaborated that restoration at 132kV grid stations in Zero Point, Rawal, F-16, F-6, D-12, F-6, I-8 and Chaklala was underway, adding that complete repair of the system will take time.
