GUJAR KHAN, Pakistan (AP) -- A woman named Rehana Yasmin struggles to keep her sick 2-year-old granddaughter cool in a sweltering hospital where working air conditioners are rare and electric fans are idle for much of the day.
Elsewhere, households can't rely on their refrigerators, and at textile factories, factory workers say they can't operate their machines for enough hours to earn their daily bread.
All are victims of Pakistan's biggest problem, one that recently brought down a government -- not the U.S. drone war in its backyard, not its permanent confrontation with India, but its inability to generate enough electricity. Pakistan, nuclear-armed, can't deliver a reliable power supply to its 180 million citizens.
"Power, power, power is the problem. It's power at home, in the workplace, on the streets," said Rizwana Kauser, head nurse at the hospital in the city of Gujar Khan, about 40 miles (65 kilometers) from the capital, Islamabad.
Power can be out for up to 20 hours a day in the summer. TV coverage may be lost in the middle of a cliffhanger cricket match. Office meetings are scheduled around anticipated power cuts. Without electric fans, mosquitoes proliferate. People get stuck in elevators. Meat rots in refrigerators.
The shortfalls that became the top issue in the recent election are estimated at 3,500 to 6,000 megawatts -- up to a third of total demand.
The problems result in part from bad bill-collecting, which leaves utility companies short of funds to pay for the oil that powers much of the production, which in turn means the state oil company can't buy enough oil on international markets.
Power theft is rampant, often consisting of simply slinging a hook over a conveniently placed electricity wire. The infrastructure of the state-controlled utility companies around the country is outdated, the companies are inefficient, and power plants are heavily dependent on oil despite Pakistan's abundant coal resources, experts say.
Fixing the problems is likely to take years, leaving Nawaz Sharif, the new prime minister, with a gargantuan task. But with Pakistanis impatient for action, the government has announced plans to pay off about $5 billion owed to companies throughout the supply chain within 60 days. It's not a long-term solution but it would at least offer the government some breathing room.
And that's just to keep the electricity flowing. Pakistan also has a problem with delivering natural gas to households and companies, and that too will need solving if the new government hopes to last.
For Rehana Yasmin, relief can't come too soon. She has been at the public hospital in Gujar Khan for a week, tending to her granddaughter who has dysentery. She brings her own water because there's no electricity to run the pump of the hospital well. She buys homemade straw fans hawked in the hospital's hallways.
For the past week, Yasmin said, "during the night we hardly have two hours of electricity and during the day, it's minimal. This lack of electricity is making children sick and making the elders sick as well."
Public hospitals like the one in Gujar Khan, which care for the majority who can't afford private hospitals, generally draw power from two grids, but nowadays, especially in the hot months, there's sometimes no electricity coming from either grid.
The hospital uses a generator during operations, but sometimes has to resort to ice to keep medicines cool.
It is a struggle simply to maintain basic sanitation, said Kauser, the head nurse. Wounds take longer to heal. And "When there is no water, there is no cleaning," she said. "How can you wash the sheets?"
In the past, power cuts ("load-shedding" in Pakistani bureaucratese) used to be much shorter and followed patterns that allowed people to plan such routine activities as scheduling an office meeting or taking a shower. But it was the newer phenomenon of "unscheduled load-shedding" and the much longer outages that raised tempers to the level of an election issue.
Dr. Ashraf Nizami of the Pakistan Medical Association said that doctors are seeing more psychological effects of load-shedding, such as stress and depression.
"It is a torture for the medical community and the patients," he said.
It's also bad for business.
The looms in one of Waheed Raamay's workshops are silent and soon to be sold as scrap metal. This workshop, a graveyard as Raamay calls it, is a sign of how the electricity crisis hurts Pakistan's economy.
"This is not just the story of this single factory. There are dozens of factories in this particular area, and there are hundreds of factories in this city that have closed down due to this power crisis," said Raamay.
