Would other states be able to provide it? I saw a post a few days ago showing that wholesale electricity prices are up 10x in nonimpacted states (California)
Yes. At the peak, Texas wholesale electricity spot-prices went up by 10,000% - 10x is child's play. What would have happened was non-essential use in California would have been priced out by desperate Texan households who'd pay almost anything to keep residences heated.
Energy companies absorb the fluctuations, except for that one company that thought it was a great idea to pass-though prices to the customers. It was a great idea when the prices were low, but many of their customers will likely experience sticker shock on their next bill.
