| Zusammenfassung |
| Wind power over Europe computed from two years of the new 100 m wind product
from ECMWF at 16 km horizontal resolution is 20% of maximum capacity of
an exemplary wind turbine power curve. This is five percent of maximum
capacity less than extrapolated from 10 m winds using model roughness in the
logarithmic law, but eight percent more than multiplying 10 m winds by a
constant factor of 1.28 as in a previous study. The result from the new data
set happens to be very close to the actual capacity factor of 21% for
European wind turbines (Boccard, 2009). The capacity factor in high power
regions between 50 and 58° N and most of northernmost Africa is almost
30%. The aggregation of wind power over Europe smooths onshore day-to-day
fluctuations to at most 7 percentage points during 80% of the year. |
