ALHAMBRA, Calif. (AP) — Southern California will survive the summer without major blackouts despite the shutdown of the San Onofre nuclear power plant, but conservation measures will be critical if there is a heat wave or a disaster, state and utility officials said Wednesday.

“We think that we’ll be able to make it through the summer,” said Lynda Ziegler, executive vice president of Southern California Edison, which operates the San Onofre plant. “If we have five or six or eight days in a row that are very, very hot, we will need people to conserve.”
