Subject: 2026 Summer Fuel Filing and CRM Surcharge
Notice Text:
Northwest filed with FERC its semi-annual fuel filing to place into effect new factors on April 1, 2026, for fuel gas used and gas lost and unaccounted-for. By this filing, Northwest proposes: (1) a decrease from 1.15% to 1.04% factor for transportation services under Rate Schedules TF-1, TF-2, TI-1, and DEX-1; (2) a decrease from 0.39% to 0.10% in the factor for underground storage services under Rate Schedules SGS-2F and SGS-2I; (3) an increase from 1.31% to 2.65% in the LNG liquefaction factor under Rate Schedules LS-2F, LS-3F, LS-2I, and LD-4I; and (4) an increase from 1.56% to 2.00% in the vaporization factor under Rate Schedules LS-2F, LS-3F, and LS- 2I and LD-4I. These changes are reflected in the tariff record for which Northwest is seeking Commission acceptance.
Since no shippers have utilized services under either Rate Schedule LS-3F or Rate Schedule LD-4I Service Agreements, Northwest proposes no change to the Rate Schedules LS-3F or LD- 4I Service Agreements liquefaction charge of $0.58646 during the upcoming April 2026 through March 2027 period.
Additionally, Northwest filed with FERC its second annual Modernization and Emissions Reduction Program Cost Recovery Mechanism (CRM)surcharge filing. Effective April 1, 2026 through March 31, 2027, the CRM surcharge is $0.03389.
A copy of the proposed filing is available on Northwest's website under Regulatory/Proposed Tariff Filings at the following link: http://www.northwest.williams.com/NWP_Portal/ (click 'Regulatory,' then 'Proposed Tariff Filings').
