Gas Turbines Industry Explained: The U.S. View
When U.S. utilities and data center developers need large amounts of reliable power quickly, they mostly turn to natural gas, and gas plants need turbines. Only a few companies make large gas turbines, and their factories cannot be expanded fast because the hottest parts, blades and vanes made of superalloys, come from a small group of casting suppliers. The result is a queue. GE Vernova, the U.S.-based maker, reported that its gas power equipment backlog plus slot reservations, agreements that hold a place in the production line, rose from 100 gigawatts to 116 GW in the second quarter of 2026 alone, and it expects at least 125 GW by the end of the year. It signed 20 GW of new gas equipment in the quarter, mostly reservations, while shipping 3 GW. Its plan is to reach 20 GW of annual turbine output in the third quarter of 2026, 24 GW in 2028 and 30 GW by 2030, so today's backlog equals several years of production. Power segment orders more than doubled, up 134% organically to $16.7 billion. Natural gas already supplies about 40% of U.S. electricity, according to the EIA.

How the chain works
GE Vernova gas power, Q2 2026
| Start of quarter | End of quarter | |
|---|---|---|
| Equipment backlog | 44 GW | 53 GW |
| Slot reservations | 56 GW | 63 GW |
| Total backlog and reservations | 100 GW | 116 GW |
| Signed in quarter | 20 GW (18 GW reservations, 2 GW orders) | Shipped 3 GW |
Why everyone wants gas turbines
Gas plants can run around the clock, can be sited near demand, and burn plentiful U.S. natural gas. According to the EIA, gas generated about 40% of U.S. electricity in 2025 and 2026. With data centers adding large, steady loads, gas is the main source of new firm capacity that can be built within a few years.
GE Vernova's chief executive Scott Strazik said in July 2026 that global demand for its products continues to grow. In the second quarter, the company booked orders for 52 heavy-duty units, including 15 of its largest HA turbines, and 61 smaller aeroderivative turbines, which can start quickly and suit on-site power for industrial sites and data centers.
Slot reservations: buying a place in line
Because factories are full, customers now sign slot reservation agreements years before delivery, then convert them into firm orders. In the second quarter of 2026, GE Vernova signed 20 GW of new gas equipment, 18 GW as reservations and 2 GW as orders, converted 10 GW of reservations to orders and shipped 3 GW. Its equipment backlog rose from 44 GW to 53 GW and reservations from 56 GW to 63 GW.
Total backlog and reservations of 116 GW compare with planned output of 20 GW a year from the third quarter of 2026, rising to 24 GW in 2028 and 30 GW by 2030. New customers are effectively buying turbines for the end of the decade.
Supply chain and money
Turbine output is limited by the hottest parts: blades and vanes made from nickel superalloys by a small number of casting suppliers. That is why makers expand step by step rather than doubling output.
Demand shows up in the numbers. GE Vernova's Power segment orders reached $16.7 billion in the second quarter of 2026, up 134% organically, and the company's total backlog reached $176 billion. Its Electrification segment, which makes grid equipment, reported data center orders of more than $5 billion so far in 2026, more than double all of 2025.
How the U.S. view differs from the China view
The Chinese version of this page looks at China's efforts to build its own heavy-duty gas turbines and its role as a supplier of castings and parts, in a country where coal, hydro and renewables matter more than gas for power.
In the U.S., gas is the largest power source and the default for new firm capacity, and the leading turbine maker is American. The question is not whether to build gas plants but how long customers must wait for turbines.
2026: the turbine queue
Data center demand and rising power prices pushed utilities and developers to order gas plants in 2026.
GE Vernova added 16 GW to its backlog and reservations in a single quarter, reaching 116 GW, while shipping only 3 GW.
With output planned at 20–30 GW a year through 2030, new orders now mean deliveries years away. Turbine factories, not gas or money, set the pace of new gas power.
- Gas turbines are the main source of new firm power in the U.S.
- Slot reservations show demand running years ahead of supply.
- Superalloy castings limit how fast turbine output can grow.
Common misreadings
MythGas plants can be built quickly anytime.
RealityGE Vernova's backlog and reservations of 116 GW compare with 20 GW of yearly output.
MythData centers only use renewable power.
RealityGE Vernova reported over $5B of data center orders in 2026, more than double 2025.
MythTurbine makers can just build more factories.
RealityOutput is planned to rise step by step: 20 GW in 2026, 24 GW in 2028, 30 GW by 2030.
MythA reservation is the same as an order.
RealityOf 20 GW signed in Q2 2026, 18 GW were reservations and 2 GW firm orders.
Demand, supply and policy: scenarios
| Scenario | Main effect | How it passes through |
|---|---|---|
| Data center demand keeps rising | Turbine orders | Longer queues, higher prices |
| AI spending slows | Reservations | Some reservations not converted to orders |
| Casting capacity expands | Turbine output | Faster deliveries |
| Natural gas prices rise | Plant economics | Less attractive versus other sources |
| Emissions rules tighten | New gas plants | Higher costs or delays |
| Aeroderivatives used for on-site power | Smaller units | Faster, flexible additions |
Supply and demand by segment
| Segment | Supply rigidity | Concentration | New demand | Policy role | What to watch |
|---|---|---|---|---|---|
| Superalloy castings | Very high | Very high | Yes | Medium | Supplier capacity |
| Heavy-duty turbines | Very high | Very high (few makers) | Yes (data centers) | High (permits) | Backlog GW |
| Aeroderivative turbines | High | High | Yes (on-site power) | Medium | Unit orders |
| Gas plant construction | High (labor, permits) | Medium | Yes | High | Plant announcements |
Supply rigidity: how long new capacity takes and whether money can speed it up. Concentration: whether output sits in a few countries or companies. The more rigid and concentrated, the more prone to shortages.
