This thesis investigates the effects of the in 2017 amended German Renewable Energy Sources Act (EEG) on an onshore wind project in Brandenburg: the Sernow wind park and its promotion of electricity. The research question for this thesis reads:

What are the options to promote wind turbines in Sernow on the German power market in regards of the EEG 2017 amendment in a business-economic feasible way?

The EEG 2017 prescribes direct marketing of electricity and the subsidy is paid as market premium in regards of market prices. In order to compare the different marketing options on the power exchange, the Sernow wind park was modelled and optimised in windPRO to obtain a generation profile on a time resolution that corresponds with the one of the market prices. The considered marketing options – called scenarios in the at hand thesis – are a day-ahead, an intraday and a mixed promotion. Furthermore, the possible participation for wind turbines on the balancing power markets is examined.

Based on the legislative framework of the EEG 2017, which switches from fixed feed-in tariffs to an auction system concerning the individual subsidy determination, different ways of promoting the generated electricity lead to the following results: even though the Intraday Scenario performs marginally better than the others, all scenarios have a very similar outcome. With the present subsidy scheme from the EEG applied on the Sernow wind park, the way of promotion does not play an important role. The results are however sensitive to different inputs, that can let the wind park become a non-feasible investment. Further, potentials could be identified for wind turbines to participate on the negative tertiary control reserve market, there are however financial obstacles due to subsidy losses and low price expectations.
