Duke Energy CORP 8-K Report, Corporate Update (Apr 1, 2019)

Filed April 1, 2019For Securities:DUKDUKBDUK-PA

Summary

Duke Energy (DUK) announced a significant development on April 1, 2019, regarding coal ash impoundment closures in North Carolina. The North Carolina Department of Environmental Quality (DEQ) has mandated the excavation of all remaining coal ash impoundments across six sites in the state, impacting Duke Energy Progress, LLC (DEP) and Duke Energy Carolinas, LLC (DEC). This directive adds substantial costs to Duke Energy's existing closure plans. Management estimates that the excavation of these nine impoundments will incur an additional cost of approximately $4 billion to $5 billion above the current aggregate project estimate of $5.6 billion. This increased expenditure, which is expected to push closure timelines beyond regulatory requirements, highlights a material financial impact for the company. Duke Energy plans to seek recovery of these additional costs through the established ratemaking process, a strategy previously employed for similar closure initiatives.
