PNG’s transmission pipeline system in the Western System service area connects with the British Columbia pipeline system operated by Enbridge Inc. (formerly Spectra Energy) near Summit Lake, British Columbia, and extends 587 kilometres to the west coast of British Columbia at Prince Rupert. The pipeline between Summit Lake and Terrace, British Columbia has been partially paralleled, or looped, with a second line to increase throughput capacity. PNG also owns and operates over 300 kilometres of lateral transmission pipelines extending into the various communities served by PNG, the most significant being dual lines extending approximately 57 kilometres into Kitimat, British Columbia. The Western System distribution system is comprised of approximately 960 kilometres of distribution pipelines and five compressor units to maintain pressure on PNG’s Western System transmission pipeline system (four of which are presently deactivated due to current demand requirements).
The Northeast System serves theFort St. John and Dawson Creek areas of British Columbia through connections with the Enbridge Inc. pipeline system at several locations. The Northeast System also connects with pipelines owned by Canadian Natural Resources Limited to obtain supply for the Fort St. John area, a producer’s pipeline to serve the Dawson Creek area, and a Canadian Natural Resources Limited gas supply pipeline to serve the Tumbler Ridge area of British Columbia. The entire Northeast System consists of approximately 243 kilometres of transmission lines, 2,202 kilometres of distribution lines and a gas processing plant near Tumbler Ridge with a capacity of 120 cubic metres per day. In the Northeast System service area, PNG(NE) continues to build out its distribution system to newcommunities and to capture new housing and commercial developments in its existing serviced communities.
