On July 1, 2025, Northern filed a Section 4 rate case with the Federal Energy Regulatory Commission. The proposed increase in rates is driven primarily by the significant capital being invested in the pipeline system to comply with pipeline safety requirements and maintain the reliability of service to customers. Northern has also proposed an update to its depreciation and negative salvage rates and a return on equity that reflects Northern’s current cost of capital.

 

Rates are expected to go into effect, subject to refund, January 1, 2026, assuming the Federal Energy Regulatory Commission suspends the rates for the full suspension period. Northern’s filing, Docket No. RP25-989-000, can be found using the following links.
