Re: Much of Pakistan blacked out.
There appears to be a lot of "fog" surrounding this!

"Why did the power outage occur?
Addressing an early morning press conference in Islamabad the next day, Ayub said that the power supply snapped at 11:41 PM on Saturday due to a “technical fault” at the Guddu power plant located in southern Pakistan’s Sindh province. The blackout was triggered by a sudden drop in the frequency of the power transmission system from 50 to 0 in less than a second.
“It had what we call a ‘cascading effect’ and shut down the power system, choking about 10,320 megawatt of electricity,” he explained. Urging people to remain patient, he later tweeted that he was personally overseeing the power restoration efforts. He said that a team was trying to restart the Tarbela power station, which would lead to a sequential restoration of power in the rest of the country.
However, the energy ministry is yet to determine the exact cause of the power crisis. “Our teams are still working in the Guddu area to investigate the reasons that caused the fault, but heavy fog is making their job difficult,” the energy minister said."

Re: Much of Pakistan blacked out.
I would say that demand regulary exceeds supply, and that there is no reliably functioning means to automatically shed load in such circumstances.
So much of the electricity is stolen that revenue is insufficient to fund an increase in generating capacity.
Theft of electricity is done both by illegal connections to infrastructure, and by corruption whereby favoured consumers are not billed, or not cut off if they fail to pay the bill.
Grid tied PV finds little favour due to administerative hurdles, and the grid voltage and frequency being too unstable for grid tie inverters to work reliably.
