What the filing saysPetition filed with the North Dakota Public Service Commission on June 18, 2026, proposing both a new tariff class for very large customers generally and a specific rate schedule for data centers. Pending PSC approval as of this research -- not yet adopted. Separately, a legislative interim committee is actively studying large-load grid impacts and may recommend further legislation; two bills changing large-power-consumer requirements were also under consideration.
