If you\u2019ve worked in midstream natural gas for more than a couple of years, you\u2019ve likely seen a shift: once hailed as a \u201cbridge fuel\u201d between coal and renewables, natural gas is now both the backbone of global energy infrastructure and a source of persistent operational headaches\u2014many of which start with the compressors that power every link in the chain. As a supplier of natural gas compressor series, I\u2019m not here to bash the equipment we sell or the industry that relies on it. I\u2019m here to call out the real, often unspoken disadvantages that keep our customers up at night, because only by naming these pain points can we solve them. Natural Gas Compressor Series<\/a><\/p>\n

<\/p>\n

Let\u2019s start with the most immediate issue: high upfront and ongoing operational costs for the entire series. When a gas producer or pipeline operator buys a single compressor, they calculate costs around that unit\u2019s horsepower, footprint, and lifespan. But a series\u2014say, three to five compressors sized to handle varying flow rates along a 100-mile trunk line\u2014doesn\u2019t scale linearly. For example, our standard 5,000-horsepower compressor costs roughly $1.2 million, but adding two more identical units for redundancy and load balancing pushes total upfront costs to over $3.5 million, not including installation, foundation work, and pre-commissioning testing. That\u2019s a steep tab for mid-sized operators working on tight capital budgets.<\/p>\n

Worse, the operational costs don\u2019t stay steady. Natural gas compressors run 24\/7, 364 days a year (they rarely shut down entirely, even for holidays), so fuel consumption is a massive expense. Modern models are slightly more efficient than 10-year-old units, but a series of compressors still uses about 2-3% of the gas it moves just to power itself. For a large pipeline moving 1 billion cubic feet of gas daily, that\u2019s 20 to 30 million cubic feet of gas wasted annually\u2014enough to heat 150,000 U.S. homes for a year. Add in maintenance: each compressor in the series needs annual tune-ups, oil changes, and valve replacements, and if one unit breaks down, the others in the series have to work harder to compensate, accelerating wear and tear. Last year, I worked with a regional operator who had four compressors in their series; when one\u2019s bearing failed, the remaining three ran 18% above their rated load for six weeks, leading to two more breakdowns and $280,000 in emergency repairs. It\u2019s a snowball effect that\u2019s hard to avoid when you\u2019re dependent on a series of interconnected equipment.<\/p>\n

Next up: strict noise and emission regulations that are harder to comply with for an entire series, not just individual units. Let\u2019s talk about noise first. Local zoning laws in areas near compressor stations often cap noise levels at 55 decibels (roughly the sound of a normal conversation) at the property line. A single large reciprocating compressor can hit 90 decibels at 50 feet\u2014loud enough to disrupt nearby residents and violate rules. But when you have an entire series running at full capacity, noise levels spike dramatically. We\u2019ve had customers in Pennsylvania and Texas who had to install $50,000 sound dampers on each compressor in their series, just to meet local noise requirements. That\u2019s a huge extra cost that\u2019s not factored in when they first price the equipment.<\/p>\n

Emissions are an even bigger headache, especially as governments tighten rules to fight climate change. Natural gas compressors emit methane\u2014a greenhouse gas 28 times more potent than CO\u2082 over a 100-year period\u2014along with volatile organic compounds (VOCs) and NO\u2093. For a single compressor, leak detection and repair (LDAR) programs can keep emissions within limits, but a series has dozens more connections, valves, and seals, all potential leak points. A 2023 EPA study found that compressor stations with three or more units have 30% higher methane emissions per unit than stations with single compressors, because the more components you have, the more chances there are for leaks. We\u2019ve had customers in California face fines of up to $50,000 for unreported leaks in their compressor series, which isn\u2019t just a financial hit\u2014it can halt operations until the leaks are fixed, costing them even more in lost revenue.<\/p>\n

Another disadvantage I see every day is the limited adaptability of compressor series to changing demand. Let\u2019s say a pipeline operator\u2019s flow needs drop by 40% in the summer, when demand for heating gas is low. A single compressor can be throttled down or shut off, but a series is built to work in sync. Most series are engineered to run at a specific range of flow rates, so if you need to operate at 50% of their rated capacity, you end up with very low efficiency. That means you\u2019re still using almost as much fuel as you would at full capacity, just moving less gas. We had a customer in the Rocky Mountains last year who had a four-compressor series sized for peak winter demand. In June, they only needed half the capacity, so they could only run two compressors\u2014but even then, the remaining two in the series had to stay on standby to compensate if one failed, wasting fuel and adding unnecessary maintenance costs.<\/p>\n

What about reliability? Compressor series are supposed to be more reliable than single units, right? After all, if one breaks, the others pick up the slack. But that\u2019s only true if the series is sized and maintained correctly. In reality, a series of compressors is a single interconnected system, so a failure in one component can bring down the entire line. For example, a faulty control valve in one compressor can cause pressure spikes that damage the other units in the series. Last year, a mid-sized pipeline in the Midwest had a control module malfunction in their third compressor, leading to a pressure surge that cracked the heat exchangers in two other units. That took three compressors out of service, not just one, and cost them a week of downtime while repairs were made. It\u2019s a domino effect that\u2019s more common than most operators realize, because they don\u2019t account for how interdependent each unit in the series is.<\/p>\n

And let\u2019s not forget about the skill gap: operating and maintaining a full compressor series requires specialized expertise that\u2019s getting harder to find. When you have a single compressor, operators can learn the basics in a few weeks, but a series of multiple units, each with its own control system, monitoring tools, and maintenance schedule, needs operators who understand how the whole system works together. We\u2019ve heard from customers that it\u2019s hard to hire and train people with the knowledge to manage these series, especially as older operators retire and take decades of hands-on experience with them. This skill gap leads to more mistakes, more breakdowns, and higher operational costs\u2014all of which are avoidable if you have the right team, but most operators don\u2019t.<\/p>\n

Now, I know what some of you are thinking: \u201cIf there are all these disadvantages, why do you sell compressor series at all?\u201d It\u2019s a fair question, and one I ask myself every day. The truth is, compressor series do have their benefits. They offer redundancy, so if one unit breaks, you don\u2019t have to shut down the entire pipeline. They\u2019re often more cost-effective than buying multiple single compressors for large-scale operations. But those benefits come with real costs that many customers don\u2019t see when they\u2019re placing an order.<\/p>\n

As a supplier, I don\u2019t want to hide these disadvantages from you. I\u2019ve spent 12 years working with compressor series, and I\u2019ve seen firsthand how these pain points can sink a project if you\u2019re not prepared. That\u2019s why I always sit down with customers before they buy, walk them through the upfront costs, the maintenance requirements, the emissions and noise regulations they\u2019ll have to comply with, and how to adapt their series to changing demand. We don\u2019t just sell equipment\u2014we work with you to build a solution that works for your specific needs, not just a one-size-fits-all series.<\/p>\n

<\/p>\n

If you\u2019re dealing with high operational costs, frequent breakdowns, or compliance issues with your current compressor series, I\u2019d love to talk. We can walk through your current setup, identify what\u2019s causing your headaches, and find a solution that balances the benefits of a compressor series with the ability to avoid those disadvantages. You don\u2019t have to figure this out alone.<\/p>\n
