Our GE frame 9E gas turbine load has decreased since the start up after the major outage.Main factor seems to be high humidity which is running more than 60% now a days.Ambient temperature vary from 22ºC to 36ºC.We have three gas turine of 130MW each.Load at GTA/B/C is 119MW/113MW/115MW respectively at 26ºC ambient temp at 63% humidiy.GTA OFF line water wash carried out a week ago.GTC OFF line water wash carried out a month ago.GTB not washed since start up.

Are you asking about efficiency or horsepower output? Seems the question is related to output rather than efficiency.
Based on your information the water washing seems to have improved the performance of the compressors on the two that were washed.
You have said nothing about the type of inlet filter, the exhaust back pressure and the question of an evaporative coolers on the inlet.
Do you have waste heat recovery and if so what kind and are there nox reduction catalyst systems installed?
All of these items can change the performance of the turbines.
Finally what kind of load sharing system so you have and is it having a effect?

I suggest you go to "Engineering Tips" and choose the mechanical forum. This question is too specialized to answer here.
Engineering Tips is a forum where your question will be analyzed by experts.
Otherwise, you should consult with GE

The efficiency of an engine depends on various factors, e.g. load factor (percentage of full load),engine size, and engine type, maintainence
