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.

Back on June 19, PCG declared its second-quarter 2013 regular cash dividend of 45.5 cents per common share. The dividend is payable July 15 to shareholders of record July 1. This evidently helps give shareholders a greater sense of security and safety in owning the shares. some summer and hot-weather safety tips at its easy-to-navigate Web site. The operator of the infamous Diablo Canyon nuclear power plant that sits along the shoreline just north of Pismo Beach is offering "...time-proven tips to help customers be aware of summertime hazards that come with hot, dry weather and certain outdoor activities." No mention of how to cope with power outages was included.
