Two German offshore wind auctions in 2017 and 2018 saw more than 50% of winning capacity with “zero bids”. The nature of these surprisingly low bids is, however, not yet clear. In our paper, we discuss four hypotheses for possible causes for the auction results: (i) the bids are expected to be profitable due to market development and technological progress, (ii) bids can be perceived as “options to build” that can be realized if projects are profitable, (iii) bids are adjusted to secure grid access, and (iv) other long term reasons not primarily driven by the profitability of the winning bids. Our results suggest that there is evidence for all hypotheses to influence the decision making of auction bidders. In fact, we suggest to see the four hypothesis as cumulative value components, which reveal the true value of winning the auction at “zero cost” in aggregate.
This paper develops an integrated fundamental investment model which considers both the gas and electricity sector. Furthermore, we adopt the theory of stochastic programming with recourse in the combined model to account for uncertainty in the gas market. This approach enables us to analyze how uncertain gas demand in other sectors affects decisions to invest in electricity generation capacities. We find an overall decrease and a reallocation of investments in gas-fired power plants. We also quantify the expected costs of ignoring uncertainty.
Economists often analyze asymmetric cost passthrough
between retail fuel prices and oil prices (‘Rockets and
Feathers’) as a proxy for market power. Such symmetries have been analyzed for different countries and time periods. However, few studies have been conducted for the German market. Furthermore, no study has differentiated between
company types in this context. In this paper, we analyze market behavior in the German diesel market. We compare the pricing strategies of independent petrol stations with the general diesel market. Independent petrol stations have no connection with popular fuel brands and therefore might decrease market power of dominating brand stations. We use an error correction model for the period from 2011 to 2012 to evaluate the specific market behavior. We conclude that asymmetric pricing behavior is given for independent petrol stations as well as for the whole German market.
