Northwest filed with FERC its semi-annual fuel filing to place into effect new factors on April 1, 2021, for
fuel gas used and gas lost and unaccounted-for. By this filing, Northwest proposes: (1) a decrease from
0.88% to 0.87% in the factor for transportation services under Rate Schedules TF-1, TF-2, TI-1, and DEX-
1; (2) an increase from 0.20% to 0.32% in the factor for underground storage services under Rate
Schedules SGS-2F and SGS-2I; (3) no change to the current 0.25% in the LNG liquefaction factor under
Rate Schedules LS-2F, LS-3F, LS-2I, and LD-4I; and, (4) an increase from 0.14% to 0.29% in the
vaporization factor under Rate Schedules LS-2F, LS-3F, and LS-2I. 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 $0.90855 during the upcoming April 2021 through March 2022 period.
