This data-file profiles gas turbines and gas turbine companies according to their manufacturing capacity. 30 companies are profiled, including the ‘big three’ – GE Vernova, Siemens Energy and Mitsubishi Heavy. 100 gas turbines are profiles. And 25 gas turbine manufacturing facilities are also covered, in order to estimate gas turbine manufacturing capacity by region and by company.
25 gas turbine manufacturing facilities are captured in this data-file, owned by major OEMs, such as GE Vernova, Siemens Energy and Mitsubishi Heavy, covering 8M m2, employing 40,000 people, with capacity to produce 70GW pa of turbines.
As of 2026, we have expanded this data-file, looking facility-by-facility, in order to estimate global gas turbine manufacturing capacity (in GW), by company and by region, as summarized in the chart below.
100 gas turbines produced by the top ten largest manufacturers are also tabulated, capturing their sizes (in MW, apples-to-apples, on a simple-cycle basis), efficiencies (in %, again, simple-cycle basis), masses (in tons) and units sold (where disclosed). Elsewhere, we have compiled more granular operating parameters for gas turbines.
High concentration is visible in this industry. It is among the more concentrated capital goods sub-sectors in our overview of market concentration. The biggest three facilities are situated at Greenville SC, Takasago Japan, Huttenstrasse Germany.
However, increasing competition is also underway in the industry, as we have recently profiled offerings from Doosan Enerbility and Shanghai Electric. Capex costs of adding gas turbine manufacturing capacity are shown in the data-file and are surprisingly low (in $/kW-pa). Other sources of competition are substitutes, such as demand shifting and other forms of gas generation.
Expansions are underway in the face of perceived turbine shortages. Mitsubishi is adding 30%. GE Vernova has said it will expand Greenville to manufacture 70-80 heavy-duty turbines per year, with 20GW capacity. Our attempt to model the entire market is described in detail in our recent report into Gas Turbine Manufacturing Capacity.
Case studies from one company, commercializing small, combined heat and power turbines, are presented in a backup tab, showing operational disclosures on cost savings, energy savings, CO2 reductions, payback periods and motivations for adopting the system.
A recent trend has been exploring smaller-scale turbines with integrated CHPs. Although please email us if you would like to discuss some of these gas turbine companies, as we have some perspectives on costs and waste heat recovery from following this space.
Our other research and data-files capture the outlook for gas turbines in the energy transition, an overview of thermodynamic cycles, a buildup of the efficiencies of gas turbines, operating parameters of gas turbines and typical economics of CCGTs.
