Keystone XL's Zombie Politics Reveal a Broken Energy Planning System

Few infrastructure projects have traveled as far without moving an inch as Keystone XL. First proposed in 2008 to carry heavy crude from Alberta's oil sands to refineries along the U.S. Gulf Coast, the pipeline has spent nearly two decades as a political football, killed by Barack Obama, resurrected by Donald Trump in his first term, and killed again by Joe Biden on his first day in office. Now, with Trump back in the White House, the question of whether Keystone XL could rise again is circulating once more, and the answer reveals something far more troubling than any single pipeline decision: the United States has no stable framework for making long-term energy infrastructure choices.

The original application, filed by TC Energy (then TransCanada) in 2008, was straightforward enough in commercial terms. Alberta's oil sands hold one of the largest petroleum reserves on Earth, and Gulf Coast refineries, particularly those in Texas and Louisiana, were specifically built to process heavy crude. Moving that oil by pipeline is cheaper and, by most measures, safer than moving it by rail. The economic logic was never seriously in dispute. What turned Keystone XL into a decade-long saga was the collision of that logic with a rapidly shifting political climate, quite literally.

What makes the Keystone XL story so instructive from a systems perspective is not the pipeline itself but the decision-making environment surrounding it. Each time a new administration reverses the previous one's ruling, the signal sent to energy investors, Indigenous communities, landowners, and climate advocates is the same: nothing is settled, and everything depends on who wins the next election. That uncertainty is not a side effect of the political process. It has become the process.

TC Energy ultimately cancelled the project in June 2021 after Biden's revocation of its presidential permit, writing off more than $2.5 billion in sunk costs. Alberta's provincial government, which had invested roughly $1.1 billion in the project, was left absorbing a significant public loss. Those numbers matter not just as balance sheet entries but as data points in a broader calculation that every future energy investor now has to make: is it worth committing capital to a cross-border project that can be erased by executive order before a shovel breaks ground?

The second-order consequence here is already visible. The uncertainty around large pipeline approvals has accelerated investment in rail transport for crude oil, which is more expensive, more carbon-intensive per barrel, and statistically more prone to spills than pipelines. In other words, the political gridlock that was partly motivated by environmental concerns may have produced an outcome that is worse on the very metrics that motivated the opposition. That is a textbook feedback loop, and it is one that neither side of the debate has been particularly eager to acknowledge.

For Keystone XL to genuinely return, the obstacles are now considerably higher than they were in 2021. TC Energy has since spun off its oil pipelines business into a separate company called South Bow, and the original project's permits, easements, and contractor agreements have largely lapsed. Restarting would not be a matter of flipping a switch. It would require a new presidential permit, fresh environmental review under the National Environmental Policy Act, renegotiation of land access across four states, and the willingness of a private company to commit billions of dollars to a project that has already been cancelled twice by executive action.

There is also the question of whether the market still needs it. Canadian oil producers have since invested heavily in the Trans Mountain Expansion pipeline, which reached completion in 2024 and now carries Alberta crude to the Pacific Coast for export to Asian markets. The urgency that once made Keystone XL feel indispensable to Canadian producers has diminished, even if it has not disappeared entirely.

What the Keystone XL saga ultimately exposes is the cost of treating infrastructure as ideology. Pipelines, transmission lines, ports, and rail corridors take decades to plan, permit, and build. They require regulatory stability that extends well beyond any single presidential term. Countries that manage energy transitions successfully, whether toward fossil fuels or away from them, tend to do so through durable institutional frameworks rather than through the whims of electoral cycles. The United States, for all its engineering capacity and capital depth, has repeatedly struggled to build that kind of continuity. Until it does, the ghost of Keystone XL will keep returning, not because the pipeline is uniquely important, but because the system that failed to resolve it never actually fixed itself.
