Wet Compression has been a reliable and proven method of injecting water into the gas turbine inlet. Wet Compression is perfectly suited for upgrading peak load machines. A power increase can help you take fuller advantage of high peak load electricity prices. Wet Compression is designed to increase the power output of the gas turbine by reducing compressor inlet temperatures, intercooling the compressor and increasing mass flow throughout the turbine.
Wet Compression can be an effective system for recovering power loss experienced at high ambient temperature. The mutual occurrence of peak load electricity demand and high ambient temperature make Wet Compression more beneficial and valuable.
Benefits can include:
- Power increase of up to 15% and potentially more depending on the frame and operational requirements *
- Up to 3% gas turbine heat rate improvement *
- Higher exhaust energy for increased steam production
- Greater operational flexibility.
These benefits can lead to the ability to produce more power in peaking and base load operation.
Wet Compression is largely independent of the ambient relative humidity. While somewhat higher performance improvement can be available in a very hot dry climate, Wet Compression can also be very effective at times of high humidity.

Besides a diligent original equipment manufacturer assessment of the gas turbine and the involved power plant components, the scope of this modernization includes:
- Compressor inlet Wet Compression water distribution system with nozzles
- Inlet duct treatment
- Wet Compression pump skid
- Piping between pump skid and distribution system
- Compressor coating (where required by gas turbine frame and version
- Compressor upgrade (depending on gas turbine frame and version)
- Modification of existing control logic Gas turbine customization (e.g. axial trust compensation and compressor drains where applicable).
Installation and commissioning of Wet Compression can require an outage from one to three weeks depending on plant and gas turbine configuration. We offer a full range of field service capabilities to help you manage your maintenance and outage schedules.
