What would be the best wind turbine option (from the available library) to cover a demand in the order of 100 MW in an wind-diesel hybrid system?

There is no simple answer to the question of which turbine is best suited to a particular application.  It is almost always necessary to model the system with several types of wind turbines, and to compare their relative economics as well as their other properties such as ease of erection, suitability for permafrost, etc.

Did you mean 100 kW?
