Natural gas-fired generation

Why the concentration exists

Gas-fired generation turns natural gas into electricity through combustion turbines, most commonly in combined-cycle configurations that pair a gas turbine with a steam turbine driven by waste heat. These systems sit at the bottleneck of the AI compute buildout because the gas turbine itself is a heavy industrial good whose production is capital-intensive and capacity-constrained. GE Vernova can build roughly 10 GW of heavy-duty gas turbines per year through 2030, against a global order book equivalent to 110 GW of power, and available manufacturing capacity is only capable of producing 60–70 GW.[10][17]

The supply constraint shows up in wait times rather than raw material scarcity. Lead times for new gas turbines are somewhere on the order of five years-plus, and one industry executive has stated that a new gas-fired generation facility cannot be brought online until 2032 because of the queue for equipment. Slot reservation agreements and deposits are the mechanism OEMs use to allocate that scarce output, with one OEM holding 29 GW of backlog and an additional 21 GW of slot reservations under contract.[2][13]

Because the bottleneck is production rate, pricing power accrues to the turbine makers. The price for natural gas turbines is expected to surge to $600/kW by the end of 2027, a 195% increase from 2019, and one chairman reported that the price of a gas turbine has gone up threefold in 24 months. EPC margins are squeezed in parallel, as costs to build natural gas-fired power plants in the US increased 66% between 2023 and 2025, with average combined-cycle project expense rising to $2,157 per kilowatt.[17][13][16]

What the evidence shows

Who supplies it

Beyond the heavy-duty trio, smaller OEMs and packagers address niche and smaller-scale segments. Solar Turbines supplies industrial gas turbines for power generation, gas transmission and compression, storage and offshore platforms, and its product line includes natural gas centrifugal compressors. GE Vernova's LM2500XPRESS aeroderivative units can start in as few as five minutes and be installed in as little as two weeks, a configuration used at the 162-MW Mountain Peak Power Plant in Keenesburg, Colorado, which features six of those units.[1][5]

Utility-scale buyers concentrate project pipelines around a small number of developers. NRG Energy has signed a project development agreement with GE Vernova and TIC to develop up to 5.4 GW of natural gas generation across four projects serving the ERCOT and PJM wholesale markets. Capital Power operates one of the largest utility-scale natural gas fleets across North America and quadrupled its capacity while raising gas weighting from under 25% to 90% over the past 15 years.[6][14]

What it depends on, and what depends on it

On the demand side, the output feeds a grid now stretched by data-center load. S&P Global projects U.S. data center demand will rise from 76 gigawatts in 2026 to 134 gigawatts by 2030, which is why behind-the-meter gas is being pursued. Behind-the-meter gas generation capacity is expected to grow by 25 GW by 2030, with one executive calling it the 'near term winner' solving for speed-to-market and affordability. Chevron, Engine No. 1, and GE Vernova plan up to 4 GW of gas-fired generation co-located with data centers in the Southeast, Midwest, and Western U.S., with operations expected by the end of 2027.[12][8][7]

Where it sits in the stack

What would break it

If demand growth outruns OEM expansion, the backlog will lengthen further. Turbine orders are expected to peak in 2026 as developers attempt to secure equipment for 63 GW of natural gas capacity additions from 2026–2030. GE Vernova expects to approach 70 GW of contractual gas power commitments by the end of 2025, with significant momentum into 2026, having installed nearly 200 machines in its gas turbine factories in a single year and added 800 production workers globally.[17][11]

What to watch

Several multi-gigawatt projects have firm in-service dates still ahead. The Maple Creek natural gas-fired power project in Sullivan County, Indiana, using a GE Vernova 7HA.03 in single-shaft configuration, is expected to enter commercial operation as soon as 2029. Oglethorpe Power's new Monroe County, Georgia plant, also using GE Vernova 7HA.03 combined-cycle technology, is expected to generate more than 1,400 MW and begin commercial operation in 2029.[4][9]

Data-center-driven behind-the-meter projects have staged commissioning through 2032. NRG Energy's first facility, with an expected capacity of 1.2 GW, is due to begin commercial operations in 2029, with the other three plants slated to come online through 2032. NextEra Energy has stated that a new gas-fired generation facility cannot be brought online until 2032 due to the queue for gas turbines.[6][13]

Capacity-add figures from third-party trackers still lie ahead of realization. Jefferies expects at least 19 GW of total available gas equipment capacity by 2028, increasing to 49 GW by 2029 and 76 GW by 2030. Yes Energy is tracking over 340 natural gas projects expected to come online between 2026 and 2031, and U.S. developers and operators plan to add 86 GW of new utility-scale electric generating capacity to the grid in 2026, a record if realized.[8][15][3]
