Pakistan’s national grid suffered a major breakdown, leaving millions of people without electricity for the second time in three months and highlighting the infrastructural weakness of the heavily indebted nation.
The energy minister, Khurram Dastgir, said the outage on Monday was caused by a large voltage surge in the south of the grid, which affected the entire network.
Supplies were being partially restored from north to the south, he added, nearly six hours after factories, hospitals and schools reported outages. The grid should be fully functioning by 10pm (1700 GMT), Dastgir said, adding: “We are trying our utmost to achieve restoration before that.”
It took hours to restore power after the last major outage, in October. A senior ministry official blamed this outage, and the frequent blackouts that Pakistan’s 220 million people suffer, on its ageing grid.
“There’s an underlying weakness in the system,” said the official, who declined to be named as they were not authorised to speak to the media. “Generators are too far from the load centres and transmission lines are too long and insufficient.”
Like much of the national infrastructure, Pakistan’s grid needs an upgrade that the government says it can ill afford.
Pakistan has enough installed power capacity to meet demand, but it lacks resources to run its oil-and-gas powered plants – and the sector is so heavily in debt that it cannot afford to invest in infrastructure and power lines.
“We have been adding capacity, but we have been doing so without improving transmission infrastructure,” Fahad Rauf, the head of research at Karachi-based brokerage Ismail Iqbal Industries, said.
China has invested heavily in Pakistan’s power sector as part of a $60bn (£48bn) infrastructure scheme that feeds into Beijing’s “belt and road” initiative to develop land and sea trade routes in Asia and beyond.
The outage affected swathes of the country. In Peshawar, a city of more than 2.3 million people, some residents said they had no drinking water because their pumps were powered by electricity. Telecom companies and several hospitals said they had switched to backup generators, but disruptions remained.
“I am facing a lot of problems because of the power outage,” said Mohammad Khurram, a Karachi resident who was accompanying his sick mother-in-law at a city hospital. “I have to keep bringing her in and out of the building because the X-ray machines and other testing units are affected.”
