Northwest will make its semi-annual fuel filing to place into effect new factors on April 1, 2019, for fuel gas used and gas lost and unaccounted-for. By this filing, Northwest proposes: (1) an increase from 1.61% to 1.64% in the transportation services factor; (2) an increase from 0.17% to 0.24% in the underground storage services factor; (3) an increase from 0.53% to 0.98% in the LNG liquefaction services factor; and, (4) no change to the current 0.53% in the LNG vaporization services factor. These changes are reflected in the tariff sheet for which Northwest is seeking Commission acceptance. Northwest is proposing no change to the LS-3F and LD-4I liquefaction charge for 2019.
