Update 1: Northern will be reviewing the Section 4 Rate Case Filing presentation during the customer call scheduled for Monday, June 16, 2025. The presentation can be found on the Regulatory and Rate Proceeding Documents webpage.

Original Notice: Northern is scheduling a customer call for Monday, June 16, 2025, at 2 p.m. CCT to discuss its upcoming Section 4 rate case filing. The need for a rate case is driven by investments in asset modernization and maintenance. From January 1, 2023, the end of the test period in Northern’s last rate case, through December 31, 2025, Northern will have placed in-service $1.6 billion of assets related to modernization and other maintenance capital. Net of depreciation, this represents $1.1 billion in non-revenue generating capital that is not being recovered under Northern’s current rates. During the customer call, Northern will describe the major components of its filing, including the planned rate increases and tariff changes.
