The North Carolina Utilities Commission has approved the proposed merger of troubled South Carolina utility SCANA with Dominion Energy.

The utilities announced the commission's approval in a news release Monday. The merger remains contingent upon approval from the Public Service Commission of South Carolina.

Previously, the merger had received approval from a number of agencies, including the U.S. Nuclear Regulatory Commission, which approved the indirect transfer of the operating license for the V.C. Summer Nuclear Station from SCANA subsidiary South Carolina Electric & Gas Co. to the Virginia-based company.

SCANA needed a buyer after spending $5 billion on a pair of reactors abandoned a year ago at V.C. Summer, costing thousands of jobs. The move spawned more than a dozen lawsuits and followed the bankruptcy of lead contractor Westinghouse.
