If a wind turbine of 2MW (of "capacity" or "max load") produces 5256 MWh in 1y, the average load (or yield) is 5256 MWh / 365 days / 24 hours / 2 MW = 0.3 Some

If a wind turbine of 2MW (of "capacity" or "max load") produces 5256 MWh in 1y, the average load (or yield) is 5256 MWh / 365 days / 24 hours / 2 MW = 0.3 Some day it will be near 0 (0% efficiency), or near 0.9 (90% efficiency). It depend on weather conditions.
