FortisBC says that customers could see up to a 50 percent reduction in natural gas supply this winter.
The drop is due to an explosion earlier this month near Shelley, the cause of which is still unknown.
Enbridge, who operates the pipeline, expects the ruptured 36 inch line to be replaced by mid-November, but according to FortisBC, both that line and the 30 inch line will only be running at 80 percent through the winter.
Fortis says it is working to secure more natural gas in the meantime, but forecasts are on a week-to-week basis.
The energy company is still asking natural gas users in the province to conserve as much as possible.
