Wind park [onshore wind (5.5)] of about 10 wind energy converters built onshore with a total net
capacity of 15 MWe and an average wind velocity of 5.5 m/s at a height of 50 m which corresponds
to the height of the hub. The average load factor is about 17.7%.

Cost estimates provided for the present study are taken from different studies and the literature, and are
given after clearance with different manufacturers and electric utilities. All cost estimates for steam cycle
plants are based on plant types already built or approved. For nuclear plants, costs incurred during the time
between plant shutdown and plant decommissioning are also taken into account and are covered by the
specific capital investment costs. Tables 7 to 9 show an overview of the input data of the analysed power
plants from a national point of view.
The progressions of fossil fuel prices are taken from the Enquete-Kommission 14 and are given to the
border of the power plant (refer to Table 10).
