Edison may retire both San Onofre nuclear units

San Onofre Nuclear Generating Station California Independent System Operator Corp summer demand electricity reliability

Southern California Edison is considering retiring both of its Pacific coast nuclear reactors, the Associated Press reports.

Both reactors at Edison’s San Onofre Nuclear Generating Station, located between San Diego and Los Angeles, have been offline since January 2012 following the discovery of serious system flaws. Keeping the combined 2,250 MW units offline has come at a price tag of $574 million, a cost that has been passed on to power customers and shareholders.

“There is a practical limit to how much we can absorb that risk,” said Edison CEO Theodore Craver in a conference call of Wall Street analysts, according to the AP.

Craver said a decision on the future of the entire facility is expected before the end of 2013.
