To get a sense of the magnitude of the power crisis hitting Texas, take a look at how it compares to the blackouts that roiled California last summer during a searing heat wave.
The California grid was short about 1 to 2 gigawatts for two evenings, while Texas has been short about 15 to 25 gigawatts for two straight days, according to Andy DeVries, a power analyst at CreditSights. And while California’s rolling blackouts left customers in the dark for a couple of hours at a time, customers in Texas have been without power for more than a day.
