This gives us a rough rule of thumb of a 1% efficiency reduction and 5% reduction in output for every 10 °C change. For every K rise in ambient temperature above ISO conditions the Gas Turbine loses 0.1% in terms of thermal efficiency and 1.47 MW of its Gross (useful) Power Output. This relationship is a problem hot climates where peak demand ...
ISO 21789:2022(en), Gas turbine applications ? Safety
The overall objective of this document is to ensure that equipment is designed, constructed, operated and maintained throughout its life in accordance with ISO 12100:2010. This document approaches gas turbine safety from an international perspective based on the content of existing, recognized ISO and IEC standards to the greatest extent possible.
Gas turbine power and thermal efficiency are usually rated at the International Organization for Standardization (ISO) conditions: 15 C/60 F, 60% relative humidity, and 101.3 kPa. Power and thermal efficiency are inversely related to ambient temperature and proportional to ambient pressure.
