The Race to Expand America's Gas Pipelines
As electrical demand surges and President Trump inks deal after deal to slash America's trade deficit by selling the world LNG, the race is on to expand and upgrade the country's aging pipelines.

Beneath the hills of Appalachia lies the nation’s largest natural gas-producing basin, yet many of the pipelines needed to move this vital resource are operating near capacity.
Meanwhile, demand for electricity is growing faster than it has in years. Data centers accounted for 50 percent of that demand growth in 2025, according to the International Energy Agency.
In the famous “Data Center Alley” of northern Virginia, energy giant Williams Companies is expanding its Transco natural gas pipeline system, while developers are proposing to build gas-fired power plants adjacent to data centers to bypass traditional grid interconnections, according to Global Energy Monitor.
Enlarging the support network for ramped-up natural gas production involves far more than installing and replacing pipes. Systems require stations that maintain the pressure to move gas over hundreds of miles, through processing plants, storage facilities, and metering stations. They also require connections to power plants, factories, export terminals, and local distribution networks.
Industry experts say this infrastructure network must continue modernizing to improve reliability and reduce supply bottlenecks.
“We need to build an awful lot more [natural gas] infrastructure, potentially 25 percent more than we currently have,” said Henry Froats, owner of Hydrotech Testing Services. “Areas with aging infrastructure will be replaced and upgraded, but the real need is expanding total capacity to handle electricity generation demand and data center growth over the next 25 years.”
Ian McPhillips, director of energy engineering and principal at BL Companies, explained it’s not just the total annual consumption that’s increasing. The fact that the majority of that increase is driven by power generation makes it tricky.
“Generation facilities are being built around the entire country to keep up with electric demand, and if those plants are using gas that would otherwise be heading to the population centers in the Northeast, significant changes will be needed to provide gas to generators during periods of cold weather when firm gas supplies are committed to the space heating markets,” he said.
Demand Surge
Natural gas accounts for 39 percent of American electricity production, according to the Energy Information Administration (EIA).
“Natural gas supply is critical as we forecast that U.S. liquefied natural gas exports expand and electricity demand rises through 2027, driven domestically by increasing demand from large computing facilities, including data centers,” EIA Administrator Tristan Abbey said in a January press release.
In May, the EIA reported that project developers plan to add 44.9 billion cubic feet per day of new natural gas pipeline capacity, which should come online in 2026 and 2027. Most of this expansion will be in Texas, and 70 percent of this new capacity is already under construction.
The timing is significant. After years of relatively stable electricity demand, utilities are preparing for sustained growth driven by data center expansion, domestic power generation, and a growing export sector for natural and liquid natural gas, the EIA said.
The agency reported that America’s natural gas exports will grow by 30 percent by 2027. At the same time, five liquid natural gas export development projects are ramping up production through the end of next year.
The United States is the world’s largest LNG exporter, eclipsing Qatar and Australia in 2022, with domestic producers now supplying 25 percent of global consumption. Nearly 70 percent is shipped to buyers in Europe, with Japanese and South Korean consumers increasing imports over the past few years.
Power generation has also risen alongside record-high electricity consumption in the United States. This number grew from 4,195 billion kilowatt-hours in 2025 to 4,271 billion kWh in 2026 and is forecasted to reach 4,397 billion kWh in 2027.
An analysis by the Interstate Natural Gas Association of America Foundation found that the United States needs to add around 34,000 miles of new natural gas pipeline and increase transmission capacity by 39 percent by 2052. Some estimates place that number much higher.
While demand for natural gas continues to climb, expanding the infrastructure needed to supply that growth presents a different challenge.
Aging Infrastructure
Existing natural gas infrastructure is showing its age, and rising costs are making both expansion and proactive maintenance difficult.
According to the Department of Transportation, bare steel, cast iron, and wrought iron transport pipes are some of the oldest energy-related pipelines operating in the United States today. Many were installed more than 60 years ago.
Scott Schwandt, president and infrastructure systems expert at Gajeske, said that many of these older metal pipe systems “are becoming increasingly exposed to spills, resulting in severe threats and significant environmental damage.”
Schwandt believes it’s paramount to identify and replace decades-old piping with more advanced high-density polyethylene (HDPE) material, which could reduce distribution leaks at pipe joints and require “substantially lower” levels of routine maintenance.
Labor and Costs
Employment in oil and gas extraction in the United States decreased by 7 percent in the Biden years between 2022 and 2024, according to market dynamics platform Taggd, dropping from 152,000 workers to around 141,000. Now, as the energy sector grows, the current workforce is aging faster than workers can be replaced — 50 percent of existing energy-sector employees are now 45 or older.
Goldman Sachs estimated there will be a need for more than 750,000 new workers in power generation by 2030. Meanwhile, the U.S. oil and gas sectors “continue to face acute workforce constraints,” according to a MADICORP report.
Rising costs associated with pipeline maintenance, buildout, and replacement are an additional complication.
“Costs are getting higher and higher. Now it’s the cost of laying down new pipelines,” said Amishkumar Patel, piping and mechanical engineering resource leader at Hargrove and Associates.
One knock-on effect of rising material and labor costs is the adoption of a reactive rather than proactive approach to pipeline maintenance.
“If you look at the increase of labor costs ... but the funding was increased by very minimal, people started looking at leaks instead of looking at entire service lines. Now they don’t inspect it if there’s not a leak,” Patel said.
Schwandt has observed a similar practice in his work in terms of existing gas pipe inspections.
“Aging distribution lines have often received little attention until a leak has been detected by other means and not through planning replacement,” Schwandt said.
Like Patel, he has observed the steady rise of material and labor costs. He believes this is causing utility companies to delay repairs across much of the network until forced into action by what he called a “critical failure.”
Patel said that some inspectors don’t report potentially problematic natural gas pipes, only those with active leaks. He doesn’t believe that technological advancements and better equipment would offset the pressures from rising demand and higher costs.
Schwandt said, “This ultimately plays into a negative spiral because proactively replacing the modern HDPE infrastructure would mostly alleviate the emergency maintenance costs that keep feeding a reactive, cyclical situation.”
Global Pipeline Boom
Despite the issues, America’s pipeline boom is just beginning. But it isn’t alone.
Construction just began on a $4 billion pipeline expansion in British Columbia, and will shortly commence on a $2.9 billion pipeline project in Alberta. Meanwhile, prompted by Iran’s attempts to close the Strait of Hormuz, multiple Gulf states are greatly expanding pipeline capacity for both oil and gas, with routes to the Arabian, Red, and Mediterranean Seas.
Even Syria, wracked by civil war from 2011 to 2024, is getting a major infrastructure boost as the world races to make Hormuz irrelevant, depriving Tehran of any leverage over global markets once and for all.
But no country is benefitting from the new energy order so much as the United States. And to keep growing what Trump likes to call “Energy Dominance”, the pipelines Democrats long blocked have become more important than ever, not just to the U.S. but to the world.

I'm Albertan. Do you have a person to replace Trump when his term is up? Hate to see all this good work go to waste.
