You might think comparing pipeline stocks is like lining up utility poles—boring, predictable, uniform. But scratch the surface and it’s more like trying to map underground rivers: invisible, complex, and full of pressure points.
The Midstream Landscape: What PAA Actually Does (and Where It Fits)
Plains All American Pipeline—PAA—runs one of North America’s largest networks for transporting crude oil. We’re talking over 18,000 miles of pipeline. Add another 140 million barrels of storage capacity across the U.S. and Canada. The company doesn’t produce oil. It doesn’t refine it. It moves it. Stores it. Connects producers to refineries. That’s the midstream: the middle child of the energy sector, often overlooked, rarely glamorous, but absolutely necessary. When there’s a bottleneck from the Permian Basin to Houston, PAA notices. When Keystone shuts down, PAA gains leverage. Their revenue model? Mostly fee-based contracts. Think toll roads for oil. Volume fluctuates, but the tolls keep coming.
And that changes everything in a downturn. While upstream producers cut rigs or declare bankruptcy, midstream firms like PAA often keep chugging along. Their cash flow is more stable. Their dividend yield? Around 6.5% as of late 2023—eye-catching in a low-interest world. But stability isn’t immunity. A prolonged drop in drilling activity eventually hits volumes. And if new pipelines keep coming online while oil production flatlines, the toll road gets crowded.
Why Midstream Is a Game of Scale and Geography
It’s not just about having pipes. It’s about having the right pipes in the right places. PAA’s strength lies in its dominance across key shale plays—especially the Permian. They’ve spent over $3 billion since 2018 expanding takeaway capacity out of West Texas. That matters because the Permian produced roughly 5.8 million barrels per day in 2023—nearly 40% of U.S. onshore output. But so do their competitors. Enterprise Products Partners has an even larger network: over 50,000 miles of pipeline. They’re not just big—they’re diversified. Natural gas, NGLs, petrochemicals. PAA is more oil-focused. That’s a strength in an oil rally, a weakness in a shift toward gas or decarbonization.
Scale brings cost advantages. Larger firms negotiate better rates, spread fixed costs thinner, and access cheaper capital. But it also brings regulatory scrutiny. And that’s where Energy Transfer enters the ring.
Enterprise Products Partners: The Quiet Giant You Can’t Ignore
EPD isn’t flashy. No CEO headlines. No aggressive investor presentations. Yet it’s the largest publicly traded midstream partnership by enterprise value—over $90 billion. It’s a bit like the Swiss Army knife of energy infrastructure: pipelines, export terminals, fractionation plants, even offshore rigs. Their Gulf Coast footprint is unmatched. They control critical export points where U.S. crude hits global markets. PAA has access, but EPD owns the door.
And because their revenue is even more diversified—only about 45% crude oil vs. PAA’s 70%—they’re less exposed to oil price swings. Their dividend coverage ratio hit 1.8x in 2022, meaning they earned nearly twice what they paid out. PAA? Around 1.4x. That cushion matters when markets tighten. We’re far from it being irrelevant.
But EPD’s size can be a burden. Bureaucracy slows innovation. Their growth rate? Modest—around 3% annually. PAA, by contrast, has been more aggressive in targeting short-cycle projects with quicker returns. Which explains why some investors prefer PAA for growth, EPD for stability.
Contract Structures: The Hidden Battleground
You’d think pipelines compete on miles of pipe. They don’t. They compete on contract terms. Take-or-pay agreements? That’s the golden ticket. A shipper signs a 10-year deal to move a minimum volume—or pay for it anyway. Locks in cash flow. EPD has more of these than PAA. In fact, over 75% of EPD’s EBITDA comes from fee-based or take-or-pay contracts. PAA’s mix is closer to 65%. Not bad, but less insulated. That said, PAA has improved this over the last five years, renegotiating expiring deals into longer-term commitments.
Here’s the thing: when oil prices crash, shippers want out. But take-or-pay contracts prevent mass walkaways. It’s like a gym membership that keeps charging you even if you stop going. And that’s why EPD weathered 2020 better than most.
Energy Transfer and the Aggressive Playbook
Energy Transfer (ET) is the brawler of the midstream world. Led by Kelcy Warren, they’ve built an empire through acquisitions and relentless expansion. Their enterprise value? Around $50 billion. Smaller than EPD, but growing faster. They’ve spent over $20 billion in acquisitions since 2015—including the controversial Dakota Access Pipeline.
ET’s strategy? High volume, lower margins, maximum coverage. They operate in every segment: crude, gas, NGLs, even fuel retail. Their dividend yield is even higher than PAA’s—around 7.2%. But so is their debt. Leverage ratio of 4.8x in 2023 versus PAA’s 4.2x. Riskier? Yes. But in a rising rate environment, debt becomes a real anchor.
And because ET owns both pipelines and gathering systems, they capture more of the value chain. It’s a vertical integration play. PAA, by contrast, focuses on trunk lines—the highways, not the on-ramps. So while ET may underbid on certain routes, they’re also more exposed to upstream volatility. You don’t see that on the surface. But it’s there.
Debt and Distributions: The Tightrope Walk
Midstream firms run on leverage. But how much is too much? The industry average is around 4.5x net debt to EBITDA. ET is above it. PAA is just below. One more rate hike, and refinancing gets painful. Interest expenses for ET jumped 34% between 2021 and 2023. PAA managed a 22% increase—better, but still significant.
And here’s the kicker: investors buy these stocks for the yield. But if distributions are funded by debt, not cash flow, that yield is a mirage. ET’s distribution coverage was 1.2x in 2022—barely above 1.0x, which is the danger line. PAA was at 1.4x. EPD at 1.8x. That’s three different risk profiles wrapped in similar-looking yield labels.
MPLX vs. PAA: The Marathon in the Permian
MPLX—Marathon Petroleum’s midstream arm—is a different beast. It was spun off in 2012, designed to capture stable cash flow from its parent’s refining operations. But it’s expanded aggressively into third-party business. Today, about 40% of its revenue comes from non-Marathon sources.
Their sweet spot? The Permian and Midwest. They’ve invested over $2.5 billion since 2020 in crude gathering and rail terminals. PAA competes directly in those areas. But MPLX has a built-in advantage: guaranteed volume from Marathon’s refineries. It’s like having a guaranteed customer. PAA must bid for every barrel. That said, overreliance on one shipper is a risk—if Marathon slows, MPLX feels it first.
And because MPLX has a more balanced asset mix (pipelines, logistics, storage), they’ve maintained a stronger investment-grade credit rating. PAA is rated BBB by S&P—just one notch above junk. MPLX? BBB+. That may not sound like much, but it means cheaper borrowing and wider investor appeal.
Frequently Asked Questions
Does PAA Face Threats from Renewable Energy?
Not directly. The midstream sector isn’t being replaced by wind or solar. But long-term demand for oil could decline. EV adoption at 40% of new car sales by 2030? That changes everything. PAA has started modest investments in carbon capture and renewable diesel infrastructure. But it’s less than 5% of capital expenditures. So yes, the risk is structural, not immediate. Experts disagree on the timeline. Some say 2040. Others say we’re already past peak oil demand. Honestly, it is unclear.
Is PAA a Buy Compared to Its Peers?
Depends on your appetite. If you want yield with moderate growth, PAA is fairly valued at around $12.50 per share (as of early 2024). EPD is pricier—$28—but safer. ET is cheaper—$11—but riskier. MPLX sits in the middle—$36, with strong parent support. I find PAA’s balance compelling, but only if you accept midstream as a long-term hold. It’s not a quick flip.
Why Isn’t Kinder Morgan Mentioned More?
Kinder Morgan (KMI) is a giant—enterprise value over $80 billion. But they’re more gas-focused. Nearly 60% of their business is natural gas pipelines and storage. PAA is oil-centric. So while they overlap in areas like Texas intrastate systems, their core markets differ. That said, KMI’s scale and BBB+ rating make them a shadow competitor—especially in acquisitions.
The Bottom Line: PAA’s Position in a Shifting Arena
PAA isn’t the biggest. It isn’t the safest. It isn’t the highest-yielding. But it occupies a strategic niche: crude oil transportation in the most prolific basin in North America. Its competitors—EPD, ET, MPLX—each have advantages. EPD has scale and diversification. ET has aggression and cost control. MPLX has captive volume and credit strength. Yet PAA remains relevant because of its Permian dominance and improving contract profile.
But—and this is important—the midstream world is shifting. Environmental pressure, decarbonization trends, and slower oil demand growth mean even stable toll roads face headwinds. You can’t just collect fees forever. The firms adapting fastest will survive. PAA’s moves into carbon capture and renewable logistics are small, but they’re steps.
My take? PAA is a hold for income investors, not a bold buy. The yield is attractive, but the long-term runway is narrowing. If you’re building a diversified energy portfolio, include it—but don’t overweight it. Because while the pipes may last decades, the crude they carry might not. And that’s the inconvenient truth no one likes to talk about at investor conferences. Suffice to say, the ground is moving. Even if the pipelines aren’t.
