E.ON is building one of the world’s largest
offshore wind farms in Denmark
Rödsand 2
In spring 2009, E.ON commenced con­
struction of Rödsand 2, south of the
island of Lolland in Denmark. The wind
farm, which is expected to be com­
pleted in autumn 2010, will be located
three kilometres west of Nysted
Havmöllepark (Nysted Wind Farm).
Rödsand 2 comprises 90 wind turbines with a collective output of 207
megawatts and will produce 800 million
kWh per year and supply electricity
to 200,000 households. Rödsand 2 will
replace power from coal-fired plants
and thus reduce carbon dioxide emissions by 700,000 tonnes per year in the
Nordic electricity system. Rödsand 2
will be constructed between Nysted
Havmöllepark, Gedser and Rödby in
southern Denmark on a 34 square
kilometre area. The site office during
construction is Rödby harbor. The wind
turbines will be shipped from Nyborg to
the wind farm. The concrete foundations
will be produced in Poland and towed
from there on barges directly to the
offshore construction site. The 115 meter high wind turbines will be located in
five rows with 18 wind turbines per row.
A total of 75 kilometres of cable
from the wind turbines will be connected to the transformer station, which is
also offshore.
E.ON is responsible for the wind
turbines, foundations and the offshore
grid system. Energinet.dk is responsible
for the transformer station and the grid
connection to land.

Impact of Rödsand 2 on the environment
sounds and vibrations into the immediate surroundings. Noise calculations are
based on the environmental investigations and have shown that levels are far
below the noise limits.
During the construction period, a
500 meter safety zone will be marked
with yellow buoys around the area and
sailing inside this area will not be permitted for safety reasons.
When the wind farm has been completed, sailing through the farm will be
allowed but it will not be permitted to
dock or access the wind turbines or the
transformer station.

During construction, the immediate
environment around the farm will be impacted. There will be a certain amount of
noise and the ocean floor will be ­affected
when the foundation is being put in place
and when cables are being laid.
E.ON will investigate the environ­
mental impact during the entire construction phase and environmental
management is an important part of
the Rödsand 2 project. A continuous and
open dialogue will be held with the Danish authorities pertaining to the project.
When the wind turbines have been
commissioned, they will emit certain
Energy for the future
Wind power is currently the most rapidly
growing renewable source of energy in
the world. While carbon dioxide emissions
are the most serious threat ever to the
global climate, wind power produces zero
emissions. Consequently, environmentally
friendly wind power is a highly prioritized
energy source worldwide.
Denmark is world-leading in wind
power utilization. Already today, nearly
one quarter of Danish electricity is derived from wind power (23 percent). In 30
years, nearly 50 percent of all electricity
in Denmark will be produced by wind
farms. Per capita, Denmark is the world
leader in terms of electricity generated
from wind. And since wind power
­replaces coal-fired power, the current
­levels of environmentally hazardous
emissions in Denmark have been
reduced by 30 percent.
Naturally, a wind turbine must be constructed where it can harness the most
wind – at sea. An offshore wind farm will
produce 50 percent more electricity than
one based onshore.
Nysted Havmöllepark, which was
formerly the world’s largest offshore wind
farm, has been in operation since 2003
outside Lolland. It is 20 percent owned by
E.ON. Nysted comprises 72 turbines with
a total output of 165 megawatts, which
jointly produce 600 million kWh and supply electricity to 140,000 households.
The facility is expected to:
• Cost approximately € 450 million
•S
upply 200,000 homes with electricity
• Have an output of 207 MW distributed
• Reduce carbon dioxide emissions by
among 90 turbines
• Produce 800 GWh per year
700,000 tonnes per year
