Item 8.01 Other Events

North Dakota Rate Case Settlement

On December 30, 2024, the North Dakota Public Service Commission (NDPSC) approved a settlement agreement between Otter Tail Power Company (OTP), a wholly owned subsidiary of Otter Tail Corporation, and certain interested parties in OTP’s general rate increase request originally filed on November 2, 2023. Per the terms of the settlement agreement, OTP will receive a $13.1 million, or 6.18%, net increase in annual base rate revenue. The net increase is reflective of an allowed rate of return on rate base of 7.53%, including an allowed rate of return on equity of 10.10% on an equity ratio of 53.5% of total capital. OTP’s revenue requirement was reduced by approximately $3.0 million primarily due to the inclusion of forecasted production tax credits plus adjustments for new customer load additions which were not included in OTP’s updated request filed on July 3, 2024. The settlement includes an earnings-sharing provision, whereby any earnings above a 10.20% return on equity will be shared, with 70% refunded to North Dakota customers and OTP retaining 30%. We anticipate the implementation of new base rates in North Dakota in the first quarter of 2025.
