LOS ANGELES (AP) — State regulators will consider whether to investigate soaring costs at the shuttered San Onofre nuclear power plant — and who should pay them.

At issue is responsibility for a bill that has reached at least $165 million for repairs, inspections and replacement electricity for a plant with crippled steam generators.

The plant located between Los Angeles and San Diego hasn’t produced power since Jan. 31.

It’s not clear when, or if, the twin reactors will return to service.

The Public Utilities Commission said Tuesday it plans the vote for Oct. 25.

The commission twice postponed considering an order requiring plant owners to disclose the potential economic hit for ratepayers.

It’s expected to take federal regulators months to review an Edison proposal to restart one reactor at reduced power.
