And that’s exactly where it gets messy. You’d think it’s just about oil moving from Alberta to Texas. But it’s not. It’s about timing, public sentiment, regulatory hurdles, and which companies have the financial cushion to wait it out. I find this overrated as a standalone catalyst—sure, it helps—but it’s one gear in a much larger machine.
Keystone Pipeline Explained: More Than Just a Pipe in the Ground
Let’s rewind. The Keystone Pipeline System was designed to transport crude oil from Canada’s oil sands in Alberta to refineries along the U.S. Gulf Coast. Phase 1 started in 2010. Phase 2 came online in 2011. The controversial Keystone XL extension? That’s where the political fireworks began. It was supposed to add 830,000 barrels per day of capacity, slicing through Montana, South Dakota, and Nebraska. Instead, it became a geopolitical football.
Construction halted in 2021 after President Biden revoked the cross-border permit. TC Energy, the Calgary-based firm behind it, suspended work and eventually terminated contracts. But the existing system—Phases 1 to 4—still runs, moving about 622,000 bpd from Hardisty, Alberta, to Nederland, Texas. That’s not nothing. It handles roughly 15% of Canada’s oil exports. And because it’s integrated with other systems, the ripple effects are real.
How the Existing Keystone System Works Today
Right now, the operational Keystone network includes four segments: Keystone, Keystone-Cushing Extension, Keystone Gulf Coast Extension, and the now-dead Keystone XL. The first three are active. They rely on pumping stations, storage terminals, and interconnects with refineries like those in Port Arthur and Houston. Think of it as a circulatory system—some arteries clogged, others still pumping. And refineries dependent on Canadian heavy crude? They’re still getting fed.
But—and this is a big but—the full economic benefit hinges on expanded capacity. Without Keystone XL, Canadian producers face bottlenecks. Rail alternatives cost $10–$15 more per barrel. That margin squeeze hits producers hard, which in turn affects pipeline utilization rates. So yes, the current system benefits from stable throughput, but its upside is capped.
Why Keystone XL Became a Political Flashpoint
It wasn’t just about oil. It was about symbolism. Environmental groups saw Keystone XL as a license to expand carbon-intensive extraction. Indigenous communities raised concerns over water contamination and treaty rights. Nebraska’s regulatory fight over the Sandhills region delayed the route for years. And then there’s the emissions math: the oil sands produce about 17% more greenhouse gases per barrel than conventional crude.
But here’s the twist: U.S. refineries built to process heavy crude can’t just switch to light shale oil seamlessly. They’re optimized for the stuff coming out of Alberta. Shut down Keystone XL, and you don’t stop the oil—you reroute it, often less efficiently. That’s why some Democratic lawmakers in refining states quietly supported the pipeline, despite party rhetoric. The issue remains: energy security vs. climate goals, and nowhere is that tension more visible.
Top Stocks That Would Gain from a Keystone Revival
Let’s cut through the noise. Not every energy stock gets a lift from this. It’s not like flipping a switch and the whole S&P 500 energy sector jumps. We’re looking at a narrow group: pipeline owners, midstream operators, and integrated oil companies with exposure to Canadian production. Some names are obvious. Others fly under the radar.
TC Energy: The Obvious Play, But Risky
TC Energy (TSX: TRP, NYSE: TRP) is the elephant in the room. It’s the sole developer and operator of the Keystone system. If Keystone XL were revived—say, through a future administration or a court decision—its stock would react fast. We’re talking about $34 billion in market cap, yields around 6.5%, and a business model built on long-term pipeline contracts. These are take-or-pay agreements, meaning shippers pay whether they use the pipe or not. That’s stability.
But—and this is critical—TC Energy already wrote down $1.3 billion on Keystone XL. It’s not sitting idle; it’s redeploying capital into LNG export projects and power transmission. So a Keystone revival would be a positive surprise, not a core growth driver. The stock isn’t priced for a miracle. That said, a reinstated permit could push shares up 15–20% in six months. Not guaranteed. But plausible.
Canadian Natural Resources and Suncor: Heavy Crude Producers With Skin in the Game
These aren’t pipeline companies. They’re oil producers. But they’re directly impacted. Canadian Natural Resources (TSX: CNQ, NYSE: CNQ) and Suncor Energy (TSX: SU, NYSE: SU) both operate large-scale oil sands projects. Their breakeven costs? Around $45–$55 per barrel. Without Keystone XL, they’re stuck with discounts on Western Canadian Select (WCS), which often trades $15–$25 below WTI.
Expand pipeline capacity, and that discount narrows. A $10 improvement in realized pricing could boost CNQ’s annual cash flow by $1.2 billion. Suncor, with its downstream refining arm, benefits twice: higher upstream margins and stable feedstock costs. But—and this is where people don’t think about this enough—both companies are diversifying into lower-carbon ventures. Suncor’s investing in hydrogen and wind. CNQ’s buying shale assets in the U.S. So while Keystone helps, it’s not their only lifeline.
Enterprise Products Partners: The Silent Beneficiary
You might not expect this. Enterprise Products Partners (NYSE: EPD) doesn’t own a mile of Keystone. It’s a U.S.-based midstream giant with 50,000 miles of pipelines. But it does have extensive Gulf Coast infrastructure—terminals, storage, and interconnects. If Keystone XL ever moves oil to Texas at scale, that oil doesn’t just vanish. It gets stored, blended, and shipped. Enterprise’s Nederland terminal? It’s less than 10 miles from Keystone’s endpoint. Coincidence? No. Strategy.
And because EPD operates on fee-based contracts, it doesn’t care where the oil comes from—only that it flows. More volume means more revenue. Their distribution yield sits at 7.2%. Stable. Predictable. A bit like a toll road for oil. And that’s exactly where the real money is—not in who drills, but in who moves and stores it.
Keystone vs. Alternatives: Is the Pipeline Still the Best Option?
Maybe not. Rail transport has surged. Canadian Pacific Kansas City (TSX: CP, NYSE: CP) moved over 180,000 carloads of crude in 2023. That’s up from near zero a decade ago. Each car holds about 700 barrels. So we’re talking 126 million barrels moved by rail last year—roughly 345,000 bpd. That’s over half of Keystone’s current capacity. Rail’s flexible. It can reach refineries off the main pipeline grid. But it’s expensive. And less safe. One derailment in Alberta in 2022 spilled 30,000 liters. Public backlash followed.
Then there’s Line 3, Enbridge’s replacement pipeline from Alberta to Wisconsin. Completed in 2021, it added 370,000 bpd. Enbridge (TSX: ENB, NYSE: ENB) now moves more Canadian crude than Keystone. Its stock has outperformed TC Energy by 8% over three years. Why? Diversified assets, better regulatory navigation, and fewer headline risks. So while Keystone grabs attention, Enbridge quietly dominates. We’re far from it being the only game in town.
Frequently Asked Questions
Is the Keystone Pipeline Still Operating?
Yes. The original Keystone system (Phases 1–4) is operational, moving oil from Alberta to Texas. The Keystone XL extension, however, was canceled in 2021 after the presidential permit was revoked. No active construction is underway, and TC Energy has moved on—officially.
Which President Cancelled the Keystone Pipeline?
President Joe Biden revoked the cross-border permit on his first day in office, January 20, 2021. The decision reversed a 2019 approval by the Trump administration. That said, the original Keystone system was never canceled—just the XL expansion.
How Does Keystone Affect Gas Prices?
Not directly. The pipeline moves heavy crude to refineries, not gasoline to consumers. But if more supply reaches refineries efficiently, it can lower refining costs. In theory, that might ease prices at the pump by a few cents—especially during supply crunches. But global oil markets dominate price trends. Keystone’s impact? Marginal at best.
The Bottom Line: Keystone Matters, But It’s Not a Market Mover
Let’s be clear about this: no single pipeline will reshape the energy sector. Keystone’s fate is symbolic as much as economic. The stocks that benefit—TC Energy, CNQ, Suncor, EPD—are solid, but they’re not one-trick ponies. I am convinced that midstream infrastructure remains undervalued, not because of Keystone, but because of consistent cash flows and high barriers to entry.
That said, if political tides turn and Keystone XL gets revived—say, after the 2024 election—TC Energy could surge. But experts disagree on how likely that is. Some analysts give it a 40% chance. Others say 15%. Honestly, it is unclear. Data is still lacking on long-term demand for heavy crude, especially as U.S. refiners adapt to lighter shale blends.
My personal recommendation? Don’t bet the farm on Keystone. But if you’re already in energy infrastructure, a small position in TC Energy or EPD adds optionality. Because when politics and energy collide, someone profits. Usually not the environment. But that’s a different article. Suffice to say, the pipe may be shut. But the conversation—and the opportunity—is wide open.
