The Office of Ratepayer Advocates is joining a San Francisco consumer group in no longer supporting the settlement over the shutdown of the San Onofre nuclear power plant and wants state regulators to reopen the case, the Los Angeles Times reports. As a result, there could be a change in how much the utilities and consumers would have to pay of the $4.7 billion in costs for shutting down San Onofre. Edison maintains the existing settlement is in consumers' best interest.
