Task 3a was a continuation of Task 3, in which a computer model for determining the economic value of wind energy to a large electric utility was developed and applied to the case of Germany. The model was adapted and used to the cases of Japan, the Netherlands, Sweden and the U.S.A. The model required wind and WECS cost data as weII as utility system plant mix and load data as input.
Because of an uncertainty in WECS costs, the approach was taken to calculate the breakeven wind turbine cost for displacing conventional fossil-fired units. The benefit of introducing wind power was mainly in fuel savings and, to a lesser extent, in displacing power capacity.
