This environmental impact assessment for Kriegers flak ... - Vattenfall

Miscellaneous
An application for the development of a wind farm
containing a maximum of 60 wind turbines was rejected
in October 2004 by the Government.
8.2.2 Lilla Middelgrund
Water depth
Between 6 and 40 meters.
Distance to coast
Approximately 20 km. The visual effects on the landscape
are therefore minimal/acceptable and the cost of
grid connection acceptable.
Scope
SufÞ cient, exact details missing.
Seabed conditions
Lilla Middelgrund is a diverse bank with large topographical
variation. Cobblestone Þ elds and blocks of
stone dominate the area with rock piles and ridges.
Local weather conditions
According to SMHI the average wind speed at the
height of 100 meters is 9,5 m/sec. These values are
calculated by 20 year long measurements from stations
at Nidingen, Vinga and Måseskär.
Conditions for grid connection
In the area, there is only the 400 kV transmission grid
to connect to. It is probably possible to connect to
the nearby station Breared but this is a worse alternative
due to the vicinity of Ringhals. It would burden
the limited west coast line further and investments in
the station will be needed. The area has a relatively
well-developed regional grid of 130 kV, which may be
a better alternative.
Environmental restrictions
Lilla Middelgrund is probably one of the most important
spawning areas for herring within Kattegatt and
one of the most important hibernation areas for water
fowl within the Baltic Sea and Kattegatt (Marine Þ shing
banks – knowledge overview and biological assessment).
For the Razorbill species, the area is thought to
be the most important hibernation area in the world
ALTERNATIVE LOCATIONS 47
(Karlsson 1998). Furthermore 14 red algae and three
brown algae species have been encountered in the area
(Karlsson 1998).
Further, the area is one of 13 Swedish areas that the
(Helsinki commission) HELCOM has classiÞ ed as an
internationally important marine protection area.
Lilla Middelgrund is a Natura 2000-area. Both the
National Board of Housing and The Swedish Environmental
Protection Agency are of the opinion that the
area should remain untouched. STEM has also crossed
the area off its list of suitable locations for wind power.
Fishing and navigation
Lilla Middelgrund is part of an area of national interest
for recreational Þ shing. Recreational Þ shing in the area
is extensive. National interest for navigation is west of
the area.
8.2.3 Stora Middelgrund
Water depth
9-15 meters.
Distance to coast
Approximately 35 km. The large distance means that
the visual effects on the landscape are virtually nonexistent.
However it means high costs for grid connection.
Scope
Stora Middelgrund is largely within the Danish economic
zone and the area within the Swedish economic
zone is probably not large enough to accommodate a
Þ nancially viable wind farm.
Seabed conditions
Information missing, but the seabed conditions are
thought to be good.
Local wind conditions
According to SMHI, the average wind speed at a height
of 100 meters is 9,5 m/sec. These values are calculated
from approximately 20 year long measurements from
the stations at Nidingen, Vinga and Måseskär.
Conditions for grid connection
The area only contains a 400 kV transmission line to
