Oil shippers on the Trans Mountain expansion (TMX) project are challenging proposed pipeline tolls filed by Canadian government-owned Trans Mountain Corp. with regulators last month, citing concerns about significant costs increases.

TMX will nearly triple the flow of crude from Alberta to Canada’s Pacific Coast to 890,000 barrels per day, and is due to start up early next year.

But it has been beset by years of regulatory delay and is expected to cost C$30.9 billion ($23.50 billion), nearly quadruple the original estimate. The Canadian government bought the pipeline in 2018 to ensure the expansion got built.

Over the past week companies including Suncor Energy, Cenovus Energy, and BP registered to intervene in Trans Mountain Corp’s toll application, which proposed a base toll of C$11-C$12 a barrel, depending on the type of crude shipped and its final destination.

“Cenovus is concerned about the escalation in costs and expenses to construct the expanded system,” the Calgary-based company wrote in a letter of comment to the Canada Energy Regulator (CER).

Trans Mountain said the pipeline toll was based on the latest project cost estimate and could rise by around C$0.07 a barrel for every extra C$100 million spent on uncapped costs, which are currently estimated at C$9.1 billion.

Uncapped costs include two specific segments of the pipeline and other factors, including indigenous and community consultation.

A number of shippers said they were concerned the uncapped cost component of the toll had increased from C$1.36 a barrel in a 2017 cost estimate to C$6.48 a barrel.

Shippers also argued against Trans Mountain’s request that the regulator approve the tolls by Sept. 14.

“Given these massive increases, additional time, and detailed information is required to confirm whether the costs were necessarily and reasonably incurred, and to verify which costs properly constitute the uncapped and capped portions of the fixed toll,” PetroChina Canada, a unit of PetroChina Company Ltd., wrote in a letter of comment.

Analysts at Stifel FirstEnergy said the outcome of the dispute should not impact the price of Canadian heavy crude, but will impact margins for shippers.

“With billions of dollars at stake, we expect this dispute process to drag out for at least several months,” Stifel FirstEnergy analyst Michael Dunn said in a research note on Monday.

Trans Mountain Corporation operates Canada’s only pipeline system transporting oil products to the West Coast. They deliver approximately 300,000 barrels of petroleum products each day through 1,150 kilometers of pipeline in Alberta and British Columbia, and 111 kilometers of pipeline in Washington state. The Trans Mountain Expansion Project will provide increased capacity to support Canadian crude oil production growth and ensure access to global energy markets. The largest project in the pipeline’s history, it involves installing approximately 980 kilometers of new pipeline, new and modified facilities including pump stations and terminals, and a new dock complex at the Westridge Marine Terminal in Burnaby, British Columbia.
