Northwest reduced available capacity at Sumas from 1,313,000 Dth/d to 800,000 Dth/d due to engine damage discovered during routine inspections on Units 7 and 8 at the Sumas Compressor Station. Current net southbound nominations through Sumas are approximately 692,000 Dth/d, Northwest said. Emergency repairs are under way and Unit 7 is expected to be in service as early as Tuesday, while Unit 8 is expected to return to service March 16, it added. Available capacity will increase to 1,000,000 Dth/d when unit 7 is placed back in service, and the station design capacity of 1,313,000 Dth/d will be restored when both units are available for service. If primary nominations exceed 800,000 Dth/d prior to Unit 7 returning to service, Northwest said it will declare a deficiency period and cut nominations accordingly. “If customers require additional supply, Northwest suggests that they source gas from Alberta or Rockies interconnections,” the pipeline said.
