San Diego Avoids Widespread Blackout With Large-Scale Outage
LCG, Feb. 28, 2002--A backup transmission connection that was in use during repairs at the San Onofre substation failed yesterday, necessitating that San Diego Gas & Electric cut power to about 210,000 customers without warning.The failure took place at 10:42 a.m., and caused Southern California Edison's San Onofre Unit 3 to shut down according to design. The loss of 1,100 megawatts of capacity resulted in the California Independent System Operator ordering SDG&E to cut 300 megawatts of demand to head off a blackout in San Diego.All or part of the following communities were affected: Blossom Valley, Bonita, Calsbad, Chula Vista, City Heights, El Cajon, Escondido, Fletcher Hills, Highland Valley, La Mesa, Lakeside, Lemon Grove, Mission Hills, Mission Valley, downtown San Diego, National City, North Park, Paradise Hills, Poway, Ramona, Rancho Bernardo, Rancho Del Rey, Rancho Santa Fe, San Marcos and Sweetwater. James P. Avery, SDG&E's senior vice president of electric transmission, said, "when the transmission connection at San Onofre was lost, that put pressure on the only other transmission line into San Diego, the Southwest Power Link. Once our proposed Valley-Rainbow Interconnect transmission line is built and placed in service, this type of incident wil not impact our customers."Lorie O'Donley, public information officer at the California Independent System Operator, said, "I couldn't tell you the last time something tripped off line since that is a pretty common occurrence. To lose a unit of 1,100, that is a pretty significant event."Power was restored to all affected customers by 11:35, and aside from expected inconveniences and lost productivity, backup power maintained operations at water treatment plants and hospital facilities.
