The costs associated with the shutdown of San Onofre nuclear plant has reached $553 million for Edison International. The parent company of Southern California Edison told investors the plant may have to be closed entirely without approval from the Nuclear Regulatory Commission to restart its troubled reactor. The update comes as summer approaches. The plant hasn't generated electricity since January 2012, because damaged to tubes carrying radioactive water was discovered.

Where will California get its energy without San Onofre's plant? What would happen if the plant had to be mothballed entirely?
