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.
