SURREY, B.C. - Most British Columbia residents will pay more for natural gas after an Enbridge pipeline exploded in October near Prince George.

FortisBC says it's received regulatory approval from the B.C. Utilities Commission on interim rates for customers to take effect Jan. 1.

Diane Roy, vice-president of regulatory affairs, says in a release that Fortis strives to deliver natural gas at the lowest reasonable cost.

But she says there has been an impact to costs associated with actions the utility had to take to stabilize supply after the rupture.

Residential customers in Vancouver Island, the Lower Mainland and the Interior will see an annual increase of about nine per cent or $68 based on average annual usage.

Those in Fort Nelson will pay about seven per cent more or $51, while those in Revelstoke receiving piped propane will see a decrease of about 11 per cent or $108.
