Status of the German Wind Energy Market and Prospects for the Future
Claudia GrotzGerman WindEnergy Association (BWE)
EWEC 2007 in Milan, Italy
German wind market
Overview on the current political and on the market situation
Wind Energy in Germany – data 2006
Installed capacity 20,622 MW
Turbines 18,685
Electricity generation 30.5 billion kWh
Share in gross electricity consumption
5.5%
Employment 73,800
Turnover 9.25 billion Euro
Export rate 62 %
Current share of RES and Wind energy in German energy sector
Current RES share in primary energy consumption: 5.3 % (2006)
Electricity sector:
• Original German target: 12.5 % share of RES electricity until 2010; target will be reached in 2007
• Currently 11.8 % share = 72.7 TWh (end 2006)
• Wind power: 5.5 % share in gross electricity consumption
Political background
Current RES target(s) in electricity sector:
• 27 % by 2020 (BMU-Leitstudie 2007) (beginning 2007)
• „More than 27%“ Government declaration on Climate Protection (26th April)
• 25 % by 2020 (Spokesmen for Environment of the Federal States branches of the Conservative Party (CDU/CSU) (March 2007)
• Conservative party (CDU) planned general programme: 30 % RES electricity until 2020 (24th April 2007)
• 35 % by 2020 (Renewable Energy Associations)
Political atmosphere positive towards RES – IPCC reports, debate on energy dependency, German EU-presidency-fight for binding RES targets at EU-level until 2020 (…)

Future challenges: Repowering
1995 2005
Capacity 600 kW 2300 kW
Rotor blade diameter 46 m 80 m
Hub hight 78 m 105 m
Energy yield 1.25 Mio. kWh/a 6 Mio. kWh/a
Full load hours 2,000 h/a 3,000 h/a
Average turbine:
Increase in capacity and efficiency:Development of turbine technology
Status of Repowering projects in 2006:• 235 turbines repowered ( replaced by 109 turbines) = decrease
of 54 %
• 81.65 MW replaced by 258 MW = increase of 210 %
Barriers – economical reasons and building restrictions • Repowering bonus and regulations in current EEG not sufficient
• Hight restrictions and distance recommendations do not allow to harvest full potential
Status of and Barriers for Repowering today
Effect of hight restriction:Same turbine, less energy yield!
Total hight 100 m 140 m
Capacity 2000 kW 2000 kW
Rotor blade diameter 80 m 80 m
Hub hight 60 m 100 m
Energy yield 4.4 Mio. kWh/a 6 Mio. kWh/a
Full load hours 2,200 h/a 3,000 h/a
On the same – not always the identical - area:• Half the number of turbines• 2-fold increase of capacity• 3-fold increase of electricity generation
At the same time: • Reduced rotation time• Increase of full load hours by 50 %• improved grid compatibility
Calculation – rule of thumb for Repowering
Target until 2020:
Accumulated capacity onnew and designated area: ca. 30,000 MWRepowering: ca. 15,000 MW
ca. 45,000 MW
Electricity generation: about 110 billion kWh/a (2.500 full load hours)
= 20% of German electricity consumption
Potential wind energy onshore until 2020 – provided repowering takes off

Future challenges: Offshore development
2,9 Mrd. Euro
2,1 Mrd. Euro
Status• 15 projects currently licensed in German North Sea (including 4 cable
connections) and 4 projects in Baltic Sea with total capacity of about5,000 MW
• 3 “near-shore” turbines installed (4.5 MW, 2.0 MW and 2.5 MW)
• No building decision for any project yet
• First German offshore wind farm: test site with 12 offshore turbines (60 MW) at Borkum West site in the North Sea (6 turbines REpower 5 M and 6 turbines Multibrid M5000); operation expected 2009
Offshore wind – current status and projections
Target German Ministry of the Environment / BMU:• 1,500 MW until 2011
• 20,000 – 25,000 MW until 2030
2,9 Mrd. Euro
2,1 Mrd. Euro
• Grid connection represents a substantial part of offshore windfarms capital cost (up to 30 %)
• New Infrastructure Planning Acceleration Act (end 2006): obligation for transmission system operators (TSOs) to bear costs for connecting offshore wind farms to the mainland grid
• Intention is also to channel the cables underground: connections to offshore wind farms will be shared by a number of projects
• New law only applies for offshore plants that will be constructed prior to 31st December 2011
• Negotiations with TSOs and project planners have started. Speed of implementation?
• Tariff: discussion about postponing planned degression of tariffs (planned for 2008)
New German offshore grid regulation
German wind market
Future challenges: Grid integration
• Production management already applied in some regions – grid expansion needs to happen more speedy
• Grid operators are obliged to expand grid
• In the meantime: demand for optimised use of grid, consideration of application of underground cable
Example for optimised grid use through overhead-line monitoring:• Depending on ambient temperature and wind speed increase of
transmission capacity up to 50 %
• Only temperature: 1 % capacity per degree (ambienttemperature / Celsius)
Grid integration – current issues
