Industrial Gas Turbines

An industrial gas turbine is a mid-size, single-shaft machine purpose-built for continuous industrial duty — typically in the 15 to 62 MW range. It is neither a re-purposed jet engine (an aeroderivative) nor a large utility frame (heavy-duty); it is a robust, moderately-sized machine designed to run steadily for years.

The class is defined by its jobs more than its size:

• Combined heat and power (cogeneration) — generating electricity while its exhaust heat is captured for steam or process heat, giving very high total fuel utilization.
• Mechanical drive — turning compressors and pumps directly (common in oil, gas, and process industries) rather than only a generator.
• Mid-scale on-site power — right-sized for a campus, plant, or facility that needs tens of megawatts, not hundreds.

Single-shaft simplicity and a mid-size envelope make these units durable and comparatively straightforward to install and maintain — a practical middle ground on the power-generation spectrum.

The three gas-turbine classes line up by scale and purpose:

• Aeroderivative (~20-70 MW) — jet-engine-derived, fast-start, high simple-cycle efficiency; the bridge-power class.
• Industrial (~15-62 MW) — mid-size single-shaft machines for cogeneration, mechanical drive, and mid-scale power. The class covered here.
• Heavy-frame (tens to hundreds of MW) — large utility machines for baseload and combined-cycle plants.

Industrial turbines overlap the aeroderivative band on output but differ in intent: an aeroderivative optimizes for fast starts and stop-start flexibility, while an industrial machine optimizes for steady, efficient continuous running and for cogeneration, where capturing exhaust heat matters more than a quick start. For an on-site plant that runs around the clock and can use its waste heat, the industrial class is often the most economical fit.

The industrial units available through Pantheon are below, flagship first. Per-unit output and fuel flexibility are shown on each tile; exact rating and configuration are confirmed at quote. The Siemens SGT line anchors the class — the ~62 MW SGT-800 down through the SGT-400 — alongside the Solar Titan 130 and Kawasaki L30A. Each links to its full specification.

Industrial units in this class run roughly 15 to 62 MW in simple cycle at simple-cycle efficiencies in the mid-30s to low-40s percent. But the class's real efficiency story is cogeneration: when the exhaust heat is captured for steam, hot water, or process heat, total fuel utilization can exceed 80% — far higher than any electricity-only figure, because energy that would otherwise leave as waste heat does useful work.

That is why industrial turbines dominate combined-heat-and-power installations: a campus, district-heating scheme, or process plant that needs both power and heat extracts far more from each unit of fuel than a power-only plant. Where only electricity is needed and speed matters, an aeroderivative may fit better; where both power and heat are used continuously, the industrial machine is hard to beat.

Industrial units are quoted per configuration on request — the figure depends on the model, condition (new, refurbished, or surplus), whether the unit is configured for power-only or cogeneration or mechanical drive, balance-of-plant, and quantity, all confirmed at quote.
