• Minister says power generation units are temporarily shut in winter at night.
• Says frequency variation in national grid triggered outage.
• Says ministry trying to restore power in next 12 hours.

LAHORE/KARACHI/QUETTA/ISLAMABAD: A countrywide power breakdown, triggered by a “frequency variation” in the national grid early Monday morning, has left large parts of the country including Karachi, Lahore, Islamabad, Peshawar and Quetta without electricity. 

Power Minister Khurrum Dastagir, while talking to Geo News, said that the power generation units are temporarily shut down in winter at night as an economic measure to save fuel costs.

“When the systems were turned on at 7:30am this morning one by one, frequency variation was reported in the southern part of the country between Jamshoro and Dadu. There was a fluctuation in voltage and power generating units were shut down one by one due to cascading impact. This is not a major crisis,” said the federal minister as the country plunged into darkness for the second time in four months.

The minister said that his ministry has started restoring some grid stations in Tarbela and Warsak. 

“Peshawar Electric Supply Company (PESCO) and some grids of Islamabad Electric Supply Company (IESCO) have already been restored,” claimed the minister.  

Talking about the breakdown in Karachi, the minister said that the matter in the port city is complicated as it has a complete electric supply system.

“We provide K-Electric about 1,000-1,100 megawatts routinely, however, it will be restored within a few hours. It is not certain how long will it take to sort this issue. However, my target is to restore electricity in the country in the next 12 hours,” said the minister. 

Before the energy ministry’s announcement, different power distribution companies had confirmed the breakdown.

According to Quetta Electric Supply Company (QESCO), the two transmission lines have tripped leaving 22 districts of Balochistan, including Quetta without power.

Karachi power update

Meanwhile, K-Electric spokesperson Imran Rana said that at approximately 7:34am today, the national grid experienced a loss of frequency, affecting the power supply to multiple cities across Pakistan

“This has also cascaded to KE’s network affecting power supply to Karachi,” Rana said, adding the KE’s network is safe and protected.

“Our teams are actively monitoring the situation and enabling restoration efforts.”

An IESCO spokesperson said that its 117 grid stations were without electricity.

Meanwhile, PESCO also confirmed the outage in areas where it supplies electricity. 

This is the second time within four months that a country was hit by a major power breakdown.

NEPRA takes notice

The National Electric Power Regulatory Authority (NEPRA), in a statement, said that it has taken “serious notice” of the power outage and directed the National Transmission & Despatch Company (NTDC) to submit a “detailed report”.

The statement also said that the regulator has previously imposed fines on similar outages in the 2021 and 2022. It also shared that NEPRA has consistently issued directives and recommendations on tackling such events in future.

Previous breakdown 

In October of last year, Karachi, Hyderabad, Sukkur, Quetta, Multan, and Faisalabad were hit by a power outage.

At that time, the power minister said that nearly 8,000 megawatts of power went offline.

Back then, Dastagir had said that the simultaneous faults in two power lines, which had triggered the breakdown, at the same time was concerning for the government. He had also announced that an in-depth inquiry was ordered and promised action.

A timeline of power breakdowns in Pakistan

The country’s generation and distribution network has suffered eight major power breakdowns during the last nine years.

In 2014 and 2017, nationwide blackouts were caused by a fault in Tarbela Power Station while fog, frequency variation and the Guddu Power Plant fault were blamed for breakdowns in 2015, 2018, 2019, 2021, 2022 and 2023.

Every time the party in power announced to conduct a comprehensive probe and vowed to rectify the issues but nothing has happened despite multiple inquiries.
