Southern California Edison asked state regulators Thursday to reject calls to reopen the settlement agreement over the closed San Onofre nuclear power plant.

In a 52-page filing with the California Public Utilities Commission, Edison argued that reopening the settlement would cause “serious harm to the public.”

The utility said reconsidering the settlement could jeopardize its lawsuit with the Japanese contractor that developed the faulty steam generators that led to the nuclear plant’s permanent closure. The contractor, Tokyo-based Mitsubishi Heavy Industries, stated that Edison is seeking $7.6 billion for loss of the San Onofre plant.

Any money that Edison wins in the case is expected to be split 50-50 with customers.

Last November, the PUC approved a $4.7-billion settlement agreement that held the nuclear plant’s co-owners, Edison and San Diego Gas & Electric, responsible for $1.4 billion of the costs and put customers on the hook for $3.3 billion.
