What is TIAC?Turbine Inlet Air Chilling (TIAC) is a power enhancementsystem that is applied to a gas turbine to enhance power

output and efficiency

Offsets the negative impact of higher ambienttemperatures

Improves operational effectiveness by stabilizing theavailable power output and efficiency

Typically applied to gas turbines at power plants

TIAC systems are based on several cooling technologies

including mechanical chilling, evaporative cooling andfogging

TIAC systems have been successfully applied to hundredsof gas turbines worldwide

What drives customer demand?

Power plant owners and operators integrate TIAC intotheir power plants to realize the significant benefits ofTIAC

Reduce project costs

Peak power enhancement without having to invest inadditional generation assets (permitting, environmental

impact, cost) Operational stability with plant output maximized year

round

Higher return on asset (more exportable kWh and

higher capacity) Improve operational flexibility

Improved power plant lifecycle cost
