Subsequent Events [Abstract] |
Subsequent Events | SUBSEQUENT EVENTS For information on subsequent events related to regulatory matters and commitments and contingencies see Notes 3 and 4, respectively. On October 10, 2018, Hurricane Michael made landfall on Florida's Panhandle as a Category 4 hurricane, the most powerful storm to hit the Florida Panhandle in recorded history. The storm caused significant damage and more than a million power outages within the service territories of Duke Energy Florida, Duke Energy Carolinas and Duke Energy Progress. Duke Energy has not completed the final accumulation of total estimated storm restoration costs incurred; however, the preliminary estimate is approximately $235 million of operation and maintenance expenses and approximately $185 million in capital costs. Given the magnitude of the storm, Duke Energy Carolinas and Duke Energy Progress intend to request approval to defer the incremental costs incurred to a regulatory asset for recovery in the next base rate cases, and Duke Energy Florida will recover these storm costs consistent with the provisions in its 2017 Second Revised and Restated Settlement Agreement.
