FortisBC is scrounging far and wide to keep natural gas flowing to its customers after a massive fire at an Enbridge pipeline near Prince George on Tuesday cut off about 60 per cent of its normal gas supply.

With one large pipeline still shut down by the incident, the province’s gas distributor is pulling new supply from an existing east-west pipeline, revaporizing liquid natural gas (LNG) stored on Vancouver Island, and is drawing gas back that would otherwise be headed to the United States.

“When a major artery like this is cut, we have some options to serve customers — we have flexibility to take gas from several points into our system,” said Dennis Swanson, FortisBC’s vice-president of energy supply and resource development.

The company was able to pull additional gas from Alberta through the Southern Crossing Pipeline, which runs close to the U.S. border.

“We also have an interconnection to the south with neighbouring utilities and they really leaned in to help us out,” said Swanson.

Northwest Natural, Puget Sound Energy and Northwest Pipe — which normally receive gas from the Enbridge pipeline — were able to reverse the flow back north.

“By operating with stored LNG, they were able to push gas back up into B.C. to help us survive this crisis,” he said.

Fortis also pushed gas from its own Mt. Hayes LNG plant on southern Vancouver Island by revaporizing the gas stored there for export and backfeeding it to from the Island to the Lower Mainland.

At the Fortis LNG plant, natural gas is cooled until it condenses into a liquid at about 1/600th of its usual volume. It can be stored in its liquid form, loaded for transport from the facilities, or converted back to …read more
