BACKGROUND INFORMATION ON THE WIND FARM BIMOLTEN
Enough electricity for approx. 14.000 households
Total installed capacity 25,2 MW (14
units) Type ENERCON E-66/18.70 Rated
power 1,8 MW per unit Rotor
diameter. 70 m Hub height 98
m Average wind speed 6,5 m / s (at hub
height) Annual output approx. 45 Mio.
kilowatt hours Total investment approx. 32
Mio. euros (transformer station
included) Emission savings gt 51.000 t
carbon dioxide (annually) (compariso
n one household 4 p. causes
emissions of approx. 9,3 t CO2 when
consuming conventional electricit

10.000 MW A MILESTONE IN THE HISTORY OF WIND
The milestone of 10.000 MW was achieved in the
wind farm Bimolten.

CO-OPERATION OF LAND OWNERS AND PLANNING COMPANIES
Co-operation concerning the development of the
wind farm of
2 planning companies ? AgRo-Energieagentur GmbH
Co. KG ? WEA Windenergie-Agentur GmbH
Land owners
to be an operator oneself

• Advantages
• - participation in considerations e.g. concerning
  the strategy, financing and implementation of the
  wind farm
• strategy can be perfectly adjusted to the local
  concerns and interests
• - share in profit

WIND FARM BIMOLTEN SUCCESS STORY BY AN EXEMPLARY
SHARE MODEL
CONCEPT Creation of a real municipal wind farm
with a profit-sharing of the land owners,
residents and citizens
Peculiarity of the lease model Economic
advantages also for residents
Peculiarity of the operator model Profit-sharin
g of land owners, residents and citizens
basically coming from this region

• Lease is not only paid to the land owners, but
  also to residents who dont have land in the wind
  farm area

• The wind farm is basically operated by 176
  limited partners including 40 land owners

addition to 83 )
?Result broad acceptance within the population
as well as support for the wind farm project

REGIONAL ASPECTS

• Fortification of the region
• added value remains in the region
• works contract for many local companies
• security for jobs
• growth of know-how
• second economic pillar for farmers by lease
  income as well as by profit-sharing in the wind
  farm
• tax income for city and community
• etc.

Renewables
The present energy mix needs an urgent change,
because fossil energy resources are
becoming rare and therefore more expensive
climatic changes make necessary a reduction
of burning fossil fuels

WIND ENERGY FACTS OF GERMANY
Wind Energy Today Energy consumption in
Germany 501 bill. kWh (year 2003/source
VDEW) Wind energy covers approx. 4 of the
energy demand in Germany Regional proportion of
wind energy in Lower Saxony 16
Schleswig-Holstein 31 in the
district of East Frisia/ Papenburg 54,2
1.240 Mio kWh this corresponds to an annual
consumption of approx. 310.000 detached
houses Saxony-Anhalt 27
Mecklenburg-Western-Pomerania 24
Aim To achieve a proportion of 25
from wind energy in Germany

• POLITICAL COSTS
• political and military protection of natural
  resources
• wars for natural resources
• dependence on the world market handicap for
  political decisions

• NUCLEAR COSTS
• ultimate waste disposal for 25,000 years
• risk of nuclear catastrophes
• circulation of nuclear material
