Importance of Successful Commissioning In the Power Industry the performance of a Turbine Inlet Air Cooling (TIAC) system is linked to the performance of the Power Plant itself by the Power Plant’s rated output that is contractually guaranteed by the Power Plant designer and/or contractor. This makes the successful commissioning of TIAC systems more mission critical than the “normal” cooling system project. A properly defined and executed commissioning plan is essential to this success. 2. Commissioning Starts During the Project Proposal Phase Properly selecting and rating the system equipment is essential to meeting performance guarantees. Accurate equipment ratings which address manufactures tolerances and system losses must be taken more seriously as compared to “normal” HVAC or refrigeration proposals because typical load diversity cannot be considered as a safety factor in equipment sizing calculations for TIAC systems. The equipment must be sized for the plants design cooling load which many instances exceeds ASHRAE 0.4% ambient design conditions. This is particularly true due to the
