I imagine each grid is built to expected temperatures. So if it unusual for the area, it is problematic. I know my parent has similar weather in Ireland about 15 years ago and all the water pipes were frozen so they lost running water. That was about 15 degrees c colder than usual, about 10 degrees colder than I ever remember growing up. Texas has had recurrent problems too with their grid. Australia has had problems due to flooding. It’s just another effect of global warming.

I’d guess wind is the biggest factor here, but it’s just not mentioned in this quote.
