Enbridge’s Line 3 Replacement is complete and will ship its first oil on Dec. 1. In Canada, that is.
The Minnesota portion – the replacement portion – has not been built, due to continual delays in Minnesota. But that does not mean that Line 3 is not in operation, nor is the Canadian Line 3 replacement a pipeline to nowhere. The new pipe meets the old pipe at the international border at Gretna, Manitoba. And the old pipe, in the U.S., continues to be in use until it is replaced.
As a result, the new pipeline, one of five pipes that makes up Enbridge Mainline system, will soon be in operation.
“We’re going into commercial service Dec. 1,” said Enbridge spokesperson David Coll on Nov. 26. “We are putting this into service because it’s brand new infrastructure that’s ready to go.”
The mainline system runs from Hardisty, Alberta, east-southeast through southern Saskatchewan and Manitoba. It crosses into North Dakota at its very northeast corner before going on through Minnesota to Superior, Wisconsin. From there the mainline system splits, going through Wisconsin and Michigan to Sarnia, Ontario, and south to Chicago, around Lake Michigan, and again to Sarnia.
While there are other export pipelines, the Enbridge mainline system is the primary conduit of Canadian oil exports from Canada to the United States.
As the old Line 3 in the United States is operating at a reduced capacity, the new line in Canada is, for now, going to run at about half its rated capacity. The Line 3 Replacement will continue to transport light and medium grades of crude oil as it does today.
Coll provided a statement by email, saying, “Enbridge had previously indicated 50,000 to 100,000 barrels per day of additional throughput on the Mainline in 2019 through various optimizations. Having the Canadian portion of the Line 3 Replacement Program (L3RP) in-service provides additional flexibility in terms of how we meet our 2019 throughput objective.
“The new Line 3 won’t have the same operating restrictions of the old line in Canada. Bringing it into service allows us the flexibility to transport more product in Canada and it allows us to maximize previously under-utilized points on the system, which can then be connected to existing Mainline pipes in the U.S. that are able to take on the capacity while still meeting all regulatory requirements, including all maximum allowable operating pressures.”
The new pipeline will run at approximately half of its rated capacity, some 400,000 barrels per day, until such time as the Minnesota portion receives final approval, is constructed and brought onstream.
“First and foremost, the Line 3 project was about enhancing the safety and integrity of infrastructure that is critical to the functioning of our society, much like a highway, a bridge, or an airport,” Leo Golden, Vice President, Line 3 Project Execution said in an emailed statement. “Today, Line 3 is one of more than 80 oil and gas pipelines and 30 major electric transmission lines that cross the Canada-U.S. border, operating as part of a single, integrated North American energy market. Access to this continental energy market is critical for consumers, industry, and governments.”
The new pipeline stretches approximately 1,070 kilometres (665 miles) from Hardisty, Alberta to Gretna, Manitoba. At an estimated cost of $5.3 billion, it represents the largest capital expenditure – which Enbridge noted is most successful stakeholder engagement undertaking – in its 70-year history in western Canada.
“We are truly grateful and humbled by the tremendous support we’ve received across Alberta, Saskatchewan and Manitoba for this project over these past six years,” said Golden. “Without that support and collaborative mindset, we wouldn’t be where we are today.”
