NEW YORK ( TheStreet) -- How critical is the operational integrity of one power substation and what can happen if just one main transmission line is out of commission?
Residents of the Central Coast of California learned some of the answers Sunday, June 23, around 9:30 p.m. More than 145,000 residences from Solvang to Cambria were without power from an outage that utility company PG&E (PCG) at first said was caused by an interruption to a main transmission line.
Early on, the news services reported that Santa Barbara County emergency dispatchers were reporting on Twitter that power lines were down in Santa Maria, the largest city in the area affected. Later, PG&E tweeted that an equipment failure at a substation had caused the outage.
At that point, I was again reminded about the power and influence of Twitter. It's being used to communicate more and more about emergencies and critical events. Remember the partial power outage at the Super Bowl in New Orleans in January? Millions turned to Twitter for the answers, but I digress.(XLU) was also down a smidge, to $36.31, at about 1 p.m. EST.
