Question

A country needs a total generation of 12,000 GWh per annum. It was decided to meet 25%
of this demand from renewable energy sources. This will be met by P1 (MW) capacity of
wind generation and P2 (MW) capacity of solar PV with the ratio P1:P2 of 5:1.
(a) Assuming that the average capacity factors of the wind generation is 35% and the solar
generation is 20%, calculate P1 and P2.
(b) If 2 MW wind turbines are used to obtain capacity P1, how many wind turbines are
required? If the rotor radius of each wind turbine is 100 m and the coefficient of
performance of each wind turbine is 0.4, calculate the average wind speed required to
obtain 2 MW. Assume an air density of 1.25 kg/m3
.
