After $3 billion spent, Keystone XL can't get oil companies to sign on

Keystone XL is facing a new challenge: The oil producers and refiners the pipeline was originally meant to serve aren't interested in it anymore. Delayed for nearly a decade by protests and regulatory roadblocks, Keystone XL got the green light from President Donald Trump in March. But the pipeline's operator, TransCanada Corp., is struggling to line up customers to ship crude from Canada to the U.S. Gulf Coast, say people familiar with the matter.TransCanada Chief Executive Russ Girling remains committed to completing Keystone XL and believes it will prove profitable in the long term, say two people familiar with his thinking. But it may be years before the company recoups its investment in the pipeline, these people say.TransCanada has spent $3 billion to date on Keystone XL, much of it on steel pipe, land rights and lobbying. Completed, the pipeline would travel 1,700 miles from Alberta to Steele City, Neb., where it would link up with existing pipelines that run to the Gulf Coast.
