| Summary/Abstract |
Offshore wind power is regarded as a crucial renewable energy technology to achieve the ambitious CO2 reduction targets of the EU. However, offshore wind power is not yet competitive with traditional electricity generation technologies, so its sustained development depends on national support policies.
Employing a DCF model, this paper scrutinizes how national regulations and geographic conditions of designated national offshore wind development areas affect profitability. The focus of the analysis is on a set of hypothetical offshore wind park scenarios from five countries (Belgium, Denmark, Germany, France, and the UK). The inclusion of geographic conditions is significant, since water depth and distance to shore influence costs and because available wind resources determine the amount of electricity produced.
The paper's findings are threefold: Firstly, profitability results indicate that currently relevant scenarios in the UK and Germany are most attractive, but that the upcoming UK Round III projects have low attractiveness. Belgium, France, and Denmark follow in the rankings successively. Secondly, there is high variation among scenarios with respect to capital costs-differences amount up to +61%. Lastly, a future scenario assuming technology improvements and learning effects suggests that remuneration levels could be lowered by ~25% by 2020.

| Summary/Abstract |
Public fast charging infrastructure (FCI) is essential for the adoption of electric vehicles (EVs). To reach higher EV penetration, investments into the development of a comprehensive and widespread fast charging network are necessary. However, current investments in FCI are only profitable in specific locations resulting in a severe lack of deployments in most areas. The wish for rapid development of both, EVs and related charging opportunities, requires political support measures for FCI. This paper investigates various support measures regarding their contribution to a comprehensive expansion of FCI through profitability enhancement. We illustrate the impact of different support measures on the profitability of three different charging power categories at three different located charging sides along the German freeway. Besides the traffic volume, the profitability of FCI strongly depends on the location's surrounding charging facilities and population characteristics and decreases with increasing charging power. Currently available support measures such as investment subsidies or the exemption from the electricity tax do not contribute significantly to a widespread expansion of FCI. Changes in the demand charges have a higher potential to support nationwide investments in FCI.
