The North Carolina Utilities Commission Public Staff has submitted a motion to intervene and comments to the Federal Energy Regulatory Commission (FERC) in support of Duke Energy's proposed reorganization. The reorganization involves the merger of Duke Energy Progress, LLC, with and into Duke Energy Carolinas, LLC, with Duke Energy Carolinas as the surviving entity. The Public Staff supports FERC's approval of the reorganization as being in the public interest, citing potential savings of more than $1 billion over twelve years and increased efficiency. However, the Public Staff emphasizes that its support does not endorse or support the specifics of Duke's proposal that are properly before the state retail regulators.
