Industrial CHP

Large industrial facilities requiring reliable base-load power with heat recovery.

Buying a Used SGT-800 — What to Know

Used SGT-800 units range $5M–$15M depending on output rating, hours, and package completeness. The high availability record means condition is generally good on well-maintained units. Verify: compressor cleanliness, DLE combustion system, and whether the unit has been upgraded to the latest output rating.

Frequently Asked Questions

What is the SGT-800 availability record?

The SGT-800 fleet has demonstrated availability above 99% across many long-term service contracts, making it one of the most reliable mid-size industrial gas turbines available.

Can an SGT-800 operate in combined cycle?

Yes. The SGT-800's exhaust temperature and flow make it well-suited for a single-pressure heat recovery steam generator (HRSG). Combined-cycle efficiency can exceed 55% in optimized plants.
