On September 30, 2019, Duke Energy Carolinas, LLC (“DEC”) filed a general rate case with the North Carolina Utilities Commission (the “NCUC”) to request an approximate overall 6.0% increase in annual retail revenues, or approximately $291 million, with an overall rate of return of approximately 7.58% based on approval of a 10.3% return on equity and a 53% equity component of the capital structure. The request is premised upon a DEC North Carolina retail rate base of $15.5 billion as of June 30, 2019, and adjusted for known and measurable changes through January 2020.

While a procedural schedule has not yet been established by the NCUC, hearings are expected to commence in early 2020. DEC requested that the NCUC approve the requested rates to be effective no later than August 1, 2020.
