Notice Text:

Northern made two separate rate filings with the Federal Energy Regulatory Commission in Northern’s rate case proceeding in Docket No. RP25-989: (1) Base Case Rates; and (2)  Interim Rates. The Federal Energy Regulatory Commission must act to accept the rates. Northern's proposal is to move the Base Case Rates into effect on January 1, 2026, but to charge the lower Interim Rates effective on that date, January 1, 2026, subject to Northern's right to terminate the Interim Rates and place the Base Case Rates in effect prospectively on 30-days’ notice.

 

The Base Case Rates tariff filing was submitted in compliance with the Commission’s July 31, 2025, suspension order in this proceeding requiring Northern to motion in the filed Base Case Rates, subject to adjustments for costs associated with plant in-service as of the end of the test period, December 31, 2025.
