That's every single winter where I live in the US. We don't have a word for it like the Germans do, though, we just call it January.

The good news is: you're on a national (or semi-national) grid, and conditions like that are more unusual than they are common across the USA.

		You want us to transport energy 1500 miles? Cold, dark winters cover enormous swathes of the US - inconveniently, often at similar times. So what - we're turning Florida into a solar park so the rest of the nation can use that while they're dark? Our energy grid can't currently handle the ability to charge electric haulers locally at any scale let alone to move an entire city's worth of energy, so the solution is not to 85x the national electric grid all at once.
