Southern California Edison will challenge a recommendation that it refund $74 million to customers who were charged operating costs for the now-closed San Onofre nuclear power plant.
Administrative law judges for the California Public Utilities Commission recommended the refund on Tuesday, saying Edison improperly kept spending money on the plant last year. They recommended a $19 million refund from the plant's co-owner, San Diego Gas & Electric.
The PUC will consider the refunds next month.
An Edison statement Wednesday says the utility will submit comments challenging the criticism.
The Southern California coastal plant stopped producing electricity last year after a small radiation leak led to the discovery of extensive damage to tubing.
But Edison kept some operations going and only announced in June that the plant would close for good.
