Aeroderivative Gas Turbines

An aeroderivative gas turbine is a stationary power-generation turbine derived from an aircraft jet engine. The engine core — compressor, combustor, and gas generator — is essentially a flight engine adapted for continuous ground-based duty, coupled to a power turbine that drives a generator.

That aviation heritage is what defines the class:

• Light and compact — high power-to-weight, so the unit ships as a factory-assembled package rather than being erected on site.
• Fast to start — full power in minutes, not the slower ramp of a heavy industrial machine.
• Modular to maintain — the gas generator can be swapped as a module, shortening overhauls.

The trade-off is scale: aeroderivatives top out around 70 MW per unit, below the hundreds of megawatts a heavy-frame machine delivers. For distributed and on-site power that ceiling is rarely the constraint — deploy speed and flexibility are what matter.

Gas turbines split into three broad classes, and the right one depends on scale and how fast you need power:

• Aeroderivative (~20-70 MW) — jet-engine-derived, fast-start, quick to install. The class covered on this page.
• Industrial (~15-62 MW) — mid-size single-shaft machines like the Siemens SGT line, built for cogeneration and mechanical drive.
• Heavy-frame (tens to hundreds of MW) — large industrial machines built for utility baseload and combined-cycle plants, at the cost of much longer lead times.

Because heavy-frame order books are booked years out, aeroderivatives have become the bridge power for data centers — energizing a site now, for the multi-year window until a grid connection or a larger plant arrives. They are less fuel-efficient than a full combined-cycle plant, but availability and deploy speed outweigh efficiency when the alternative is waiting.

The aeroderivative units available through Pantheon are below, flagship first. Each is a jet-engine-derived machine in the ~20-70 MW class; per-unit output and fuel flexibility are shown on each tile, with exact rating and configuration confirmed at quote. The GE Vernova LM2500 and LM6000 and the trailer-mounted TM2500 are the volume workhorses; the Rolls-Royce Trent 60 and Pratt & Whitney FT4 round out the class. Each links to its full specification.

Aeroderivative units in this class run roughly 20 to 70 MW in simple cycle, at simple-cycle efficiencies in the high-30s to low-40s percent — higher than most heavy frames of comparable size, a direct benefit of the modern aero engine core. Most are dual-fuel or multi-fuel (natural gas with a liquid-fuel backup), and many current-generation units offer hydrogen co-firing as gas blends evolve.

Where aeroderivatives give ground is at the top end: a single unit cannot match a heavy frame's hundreds of megawatts, and in a full combined-cycle plant the heavy frame's exhaust drives a steam bottoming cycle to higher plant efficiency. For on-site power the practical answer is often to run several aeroderivative units in parallel — adding capacity in fast, modular increments rather than committing to one large, long-lead machine.

Aeroderivative units are quoted per configuration on request — the figure depends on the model, condition (new, refurbished, or surplus), fuel system, balance-of-plant, and quantity, all confirmed at quote. Tell us the output band and timeline you are planning around and we will return availability and a facility-fit review.

Figures on this page are representative public manufacturer specifications for the aeroderivative class and the models shown — not a specification of any specific unit. Actual output, efficiency, condition, and configuration vary by unit and are confirmed at quote; nothing here is an offer, a price, or a warranty.
