The North Dakota Public Service Commission on July 2 suspended proposed tariff changes and issued a notice of opportunity for hearing in Otter Tail Power Company’s thermal-market energy pricing rider (case PU25-203).

Commissioners said the filing, submitted June 9, proposes a new rider to establish a thermal-technology market energy rate. The tariff would be new to North Dakota; commissioners noted Otter Tail has already filed a version in South Dakota and plans to seek approval in Minnesota. The commission will consider whether the proposed tariff revisions and rates are just and reasonable.

The commission invited interested persons to comment on the application and said written requests for a hearing must identify the requester’s interest and reasons. Comments and hearing requests must be received by Aug. 18, 2025. The commission may decide the matter without a formal hearing if deemed appropriate.

Commissioner Hogan Hafford moved to suspend the rates and issue the notice of opportunity for hearing; the motion passed on a voice vote. The suspension begins the administrative process to review the tariff in case PU25-203.
