The California Public Utilities Commission has scheduled public hearings Tuesday in San Diego on whether energy customers are due money back during an 18-month period the San Onofre Nuclear Generating Station was off line.
The hearings are part of the state agency's investigation into costs associated with the troubled facility and ratepayers' responsibility to absorb those costs.
The time period in question stretches from January 2012, when the plant was shut down after leaking radioactive steam, to June 7 of this year, when Edison formally announced it planned top close the facility permanently.
The utilities commission is looking into whether customers of Southern California Edison (SCE) and San Diego Gas and Electric (SDG&E) are due refunds or rate reductions related to the outage period and the permanent closure.
The agency is considering removing all costs related to the San Onofre shutdown from the utility rates going forward and whether to refund costs already collected in rates going back to January 2012.
Just how much that means in refunds or rate reductions isn't known.
