What is Pacific Northern Gas? Pacific Northern Gas is a natural gas company that operates one pipeline in northwest B.C., serving over 40,000 residential, commercial and industrial customers along the Highway 16 corridor. The Western Transmission Gas Line connects to an Enbridge pipeline at Summit Lake, near Prince George, which gets its gas from sources in the northeast, and terminates in Prince Rupert and Kitimat. It has been operating at reduced capacity since losing a few of its major industrial customers over the past 20 years — Prince Rupert’s pulp mill shut down in 2001, Kitimat’s methanol and ammonia facility followed in 2005 and the Kitimat pulp and paper mill closed its doors in 2010.
