Yes, we actually had a blackout in one area of our city yesterday! My brother, in Houston, sent out an alert about probable rolling blackouts there today.
The explanation is that the power companies are doing 'work and upgrading' during this early spring period! If it's already around 90* here in April I dread later on!
Rolling power black outs...
Strange, but that's how it got started in California, that led to about a 30 billion drain on the state's treasury. Later led to the recall of then Gov. Davis, then replaced by the "Terminator." Wacky, huh!
