STATUS OF WIND ENERGY DEVELOPMENT AS OF 31 DECEMBER 2012

In the course of calendar year 2012, 1,008 wind turbine generators with a total capacity of

2,439.46 MW were installed in Germany. As of 31 December 2012, there were a total of 23,040

operational wind turbine generators. The total installed capacity was 31,331.90 MW.

Table 1 shows an overview of the status of the wind energy development as of 31 December 2012.

Additions to land-based wind energy comprise of new and repowering projects, along with offshore

wind projects. Individual components of these additions are described in more detail in their respective

sections.

It should be noted that the values for repowering and dismantling of wind turbine generators are non-

binding, since a central turbine registry that would correctly report such values does not exist. The

provided trend values were determined within the framework of a statistical data collection. This subject

matter is examined more closely in the section titled Repowering.

Figure 1 shows the development of the annual newly installed capacity, differentiated between new

projects and repowering projects onshore as well as offshore wind energy projects. Also shown is the

annual dismantled capacity.

STATUS OF OFFSHORE-WIND ENERGY DEVELOPMENT

Within 2012, 16 offshore wind

turbine generators with a combined

capacity of 80 MW fed into the

grid for the first time. At the end of

2012, a total capacity of

280.3 MW from offshore wind

turbines was connected to the grid.

109 foundation structures were

installed out at sea.

TENDENCIES IN REPOWERING AND DISMANTLING OF WIND TURBINE GENERATORS

No binding values exist for the development of repowering in Germany. This is due to the absence of a

central turbine registry that would allow for these projects to be accounted for separately. Because of

this reason, only tendencies can be identified in the area of repowering and dismantling.

In the framework of the statistical data collection, construction of 140 repowering turbines with a total

capacity of around 355 MW could be identified for 2012. At the same time, the dismantling of 224

wind turbine generators with a total capacity of 235 MW was identified.

The available data shows that during 2012, repowering occurred mainly in Schleswig-Holstein and

Lower Saxony, because the majority of turbines that had come into their repowering age were located

here. But, repowering was also realized in federal states located in the central and the south regions of

Germany.

The data basis for the numbers cited here is information provided by manufacturers and larger

planning bureaus, as well as own research primarily of press releases. This approach allowed several

paths of information gathering to be taken. Still, it must be assumed that not all realized repowering

projects in 2012 were identified this way. Considering these circumstances, a larger number of turbines

were dismantled than previously determined.

The following circumstances complicate the identification of repowering projects:

Change of manufacturer between the old and the new project, resulting in the manufacturer ofthe turbines for new project having no knowledge about the details of the old project.

Old turbines may be located in counties adjacent to the new project, by which a repowering isnot readily apparent and also often unbeknownst to the permitting agencies.

Based on the current regulations of the Renewable Energy Law 2012 (EEG 2012), in many casesone old turbine is replaced by one new turbine. This means that old turbines are being partially

brokered to adjacent projects, if the number of dismantled turbines is larger than the number of

new ones. Hence, two or more repowering projects can come out of one old project.

Many of the repowering activities currently in progress are being realized by local operatorsand so-called citizens wind farms (Brgerwindparks) and thus are unknown on a national

level.

Lack of a central turbine registry, including capturing repowering information.To analyze the situation around the area of repowering and with that the dismantling of old turbines

more comprehensively, further research is planned.

AVERAGE TURBINE CONFIGURATION

Turbines newly installed in 2012 had an

average capacity of about 2,420 kW.

The average capacity per wind turbine

generator in the total inventory on

31 December 2012 was about 1,360 kW.

REGIONAL DISTRIBUTION OF WIND ENERGY DEVELOPMENT

During 2012, the northern federal states had the largest number of new constructions. Lower Saxony

with about 15 % and Schleswig-Holstein with around 14 % occupy first and second place, followed by

Mecklenburg-West Pomerania with about 13 %. Together, the northern federal states make up more

than 40 % of the newly installed capacity.

Rhineland-Palatinate, a federal state in the south of Germany, comes in at fourth place in relation to

the total installed capacity, about 12 % of the all new construction happened there. The state is

followed by Brandenburg in fifth place with about 10 %.

The detailed analysis according to all federal states is shown in Table 4. Next to the new construction

data for 2012, the average turbine configuration installed in the individual federal states for thetimeframe in question is also shown.

of Germany.

CalendarYear 2012


Attention must be paid to the fact that, because

of variations compared to the statistical databasis of previous years, the cumulative total

capacity and number of turbines in the

individual federal states was determined

based on the states percentage share of the

total installed capacity Germany-wide.

Figure 6 graphically illustrates the distribution

of the installed total capacity across the

North, Central, South and Sea regions

with respect to development over time.

Especially during the 90's, a clear shift of new

construction from region "North" to region

"Central" can be observed.

Since about 2006, the northern share in the

Germany-wide installed total capacity has

remained relatively constant at 42-44 %.

Figure 7 Average Hub Height of Wind Turbine Generators installed in 2012 acrossthe Federal States of Germany

When comparing federal states, the value for Schleswig-Holstein is particularly conspicuous: The

average hub height of turbines installed in this state during 2012 is 81.7 m. This number significantly

influences the Germany-wide average value: When leaving Schleswig-Holstein out of the calculation,

the average hub height of all wind turbine generators installed in Germany in 2012 equates to

114.1 meters. The average hub height of wind turbines installed in Schleswig-Holstein is thus about

32 meters less than the Germany-wide average without Schleswig-Holstein.

It is apparent that the largest average hub heights are being installed in the southern federal states,

namely Bavaria, Baden-Wuerttemberg and Rhineland-Palatinate. These locations have comparatively

low wind speeds, so turbine technology with large hub heights and large rotor diameters are being

employed to optimize energy yields.
