Area classification | ||||||||||||||
|
The total model area is: 678 km2 while the area above land is: 398 km2. The land area is classified in four groups according to the average wind speed at 50 meters height. The first and largest group cover the land area where the average wind speeds is above 6 m/s. The subsequent groups covers reduced areas as the average wind speed is increased to above 7 m/s, 8 m/s and 9 m/s. | ||||||||||||||
|
|||||||||||||||
|
The suitability of an area for wind energy purposes depends on the size of high wind speed areas. Further it will be an advantage if the high wind speed areas are grouped or connected. Table 1 classifies areas according to minimum wind speed and minimum size of connected sub-areas. | ||||||||||||||

Energy production | ||||||||||||||
|
The maximum theoretical energy production from the total land area with wind speed above 6 m/s is: 18296 GWh /year |
 |
|||||||||||||
|
|||||||||||||||
|
The energy production is based on an installed capacity of 15MW/km2.
The installed capacity will only be obtained when the wind speed typically exceeds 12-13 m/s.
For lower wind speeds a wind turbine produces its installed capacity only a fraction of the time, usually
expressed as full load hours. The right figure gives the relation between full load hours and average
wind speed used in the energy calculations in this study:
