Summary
Duke Energy (DUK) filed an 8-K on March 14, 2022, to disclose a significant development regarding its Indiana subsidiary, Duke Energy Indiana, LLC (DEI). The Indiana Supreme Court reversed a prior regulatory decision that allowed DEI to recover approximately $211 million in coal ash closure costs incurred before a 2020 rate order. The Court ruled that such recovery would violate prohibitions against retroactive ratemaking without prior regulatory approval. As a direct consequence, DEI anticipates recognizing pre-tax charges of $250 million to $275 million in the first quarter of 2022, related to these disallowed coal ash closure costs, accrued interest, and other expenses. Duke Energy Corporation's share of these charges, after accounting for a minority interest sale in its Indiana holding company, is estimated to be between $222 million and $245 million. This development primarily impacts past expenditures and is stated not to affect forecasted coal ash costs.
