Energy infrastructure construction in the United States has entered a period of compressed urgency. Multiple demand signals — AI data centers, industrial reshoring, electrification, and a geopolitical push to become the world's dominant LNG supplier — are hitting the grid and the construction market simultaneously. The result is one of the broadest energy infrastructure buildout pipelines in decades, with active construction happening at both ends of the value chain: at the gas wellhead and LNG terminal, and at the transmission towers and substations serving a grid under sustained load growth.

LNG Export Terminals: A Historic Ramp-Up

The United States is in the middle of the largest expansion of LNG export capacity in its history. According to the U.S. Energy Information Administration's May 2026 report, U.S. LNG exports are projected to grow nearly 30 percent by 2027, reaching 18.7 billion cubic feet per day (Bcf/d) in 2026 and 20.5 Bcf/d in 2027. The peak export capacity of U.S. LNG terminals currently stands at 18.3 Bcf/d.

Several major terminals are in active construction or early-ramp operation right now:

• Golden Pass LNG (Sabine Pass, Texas): A joint venture between QatarEnergy and ExxonMobil, Golden Pass produced its first LNG from Train 1 on March 30, 2026 — a historic milestone for a project that has been in development for years. An initial cargo is expected to depart in Q2 2026. Trains 2 and 3 are expected to begin service in 2027.
• Corpus Christi LNG Stage 3 (Corpus Christi, Texas): Cheniere Energy's expansion of its existing terminal is nearing completion of a seven-train midscale expansion. Trains 1 through 5 have reached substantial completion, and the remaining two trains are expected to complete by the end of 2026. Cheniere also reached a positive Final Investment Decision in June 2025 on a further expansion — Corpus Christi Midscale Trains 8 and 9 — and filed a FERC application in February 2026 for a proposed Stage 4 development.
• Port Arthur LNG Phase 1 (Jefferson County, Texas): A joint venture between Sempra Infrastructure and ConocoPhillips, Port Arthur LNG represents a $13 billion investment currently under construction, with Train 1 expected to achieve commercial operation in 2027 and Train 2 in 2028. Bechtel Energy is the EPC contractor. The Louisiana and Texas Connector pipelines — which will supply feedstock — are also under construction. Across Phase 1 and Phase 2 combined, more than $26 billion is projected to be invested through 2031.

Europe's energy security concerns are a major driver of U.S. LNG export growth. In 2025, Europe received 10.3 Bcf/d of U.S. LNG — a record, and up from 6.3 Bcf/d in 2024 — representing 68 percent of total U.S. LNG exports.

The Grain Belt Express: The Biggest Private Transmission Project in U.S. History

While LNG terminals dominate the energy construction headlines, the transmission side of the grid is seeing its own landmark project move into the construction phase. The Grain Belt Express (GBX) — an $11 billion, 800-mile, 600-kilovolt high-voltage direct current (HVDC) transmission line — is the largest private-sector-led transmission project in U.S. history.

Construction began in 2026 and is expected to take three years, with the line operational in 2029. The project spans Kansas, Missouri, Illinois, and Indiana, delivering 5,000 megawatts of capacity and enabling bidirectional power flow. Developer Invenergy awarded a $1.7 billion first-phase contract to Quanta Services and Kiewit Energy Group, creating more than 4,000 construction jobs. Prysmian North America will supply 12,500 miles of overhead conductors, supported by a 50,000-square-foot factory expansion in Williamsport, Pennsylvania. All four states have approved the line as a project in the public interest. EIA projects the line will generate $52 billion in energy cost savings over 15 years.

Utility Grid Spending: $1.4 Trillion Through 2030

Beyond individual megaprojects, U.S. investor-owned utilities have collectively raised their capital spending plans to a record $1.4 trillion through 2030 — a 27 percent increase from prior plans of $1.1 trillion, according to a 2026 analysis by the PowerLines non-profit. The South (Texas to Maryland) is the most active region with $572 billion in planned spending; the Midwest follows at $272 billion. Nearly half of total planned spending is directed to transmission and distribution infrastructure, with about 30 percent targeting generation.

The primary drivers are AI data center load growth, aging infrastructure, electrification of transportation and buildings, and climate-related resilience requirements. Duke Energy, NextEra Energy, Southern Company, and PG&E are among the largest investors. In 2025 alone, utilities sought $31 billion in rate increases — more than double the prior year — as capital expenditure outpaced revenue growth.

Wind Energy: New Projects Starting Construction in 2026

Several large wind energy projects are entering or nearing construction in 2026 and 2027:

• SunZia Wind (New Mexico): A 3.5 GW onshore project by Pattern Energy Group — one of the largest wind projects in U.S. history — is expected to begin construction in September 2026, linked to the SunZia Transmission Project. Cost: $3 billion. It will supply energy to 1 million homes and create 2,000 construction jobs.
• Coastal Virginia Offshore Wind (CVOW): Dominion Energy's 2.6 GW offshore wind project — the largest offshore wind project in the U.S. — is targeting construction start in late 2026, with a project cost of $10.7 billion.
• Canisteo Wind Farm (New York): A 250 MW project in Steuben County expected to begin construction in early 2026, with a $550 million investment.

What This Means for the Construction Market

Energy infrastructure construction is among the most specialized segments in the industry, requiring contractors with experience in marine and industrial construction (LNG terminals), high-voltage electrical systems (transmission), and large-scale civil work (wind foundations and transmission corridors). The pipeline described above represents hundreds of billions of dollars in active and near-term projects — distributed across the Gulf Coast, the Midwest, the Mid-Atlantic, and the Mountain West.

For owners, developers, and GCs tracking market conditions, energy infrastructure is notable for two reasons: it tends to be largely independent of commercial real estate cycles, and it is driven by long-term contracted demand rather than speculative investment. These projects will be built regardless of interest rate conditions or office vacancy rates.
