4Some facts about GT24/26

The GT24/GT26 Story

� A GT26 in combined cycle, produces enoughpower (400 MW) to provide energy for500,000 people.

� The turbine inlet temperature is 1280°C, closeto the melting point of the blades which requireadvanced cooling methods.

� The 120 ton shaft, with a diameter of more than3 metres, rotates 50 times per second.
