“…Possible options range from the completion of deregulation of the electricity market (in order to contain market power and make price ceilings redundant) to regionally differentiated wholesale prices (for better signalling of regional capacity constraints) right through to accelerated authorisation procedures for building new infrastructure [14,18,28]. In the area of energy transformation policy, incentives for a more demand-based feed-in of electricity from renewable energy sources could be set [29][30][31][32]. A fundamental strengthening of the emissions trading scheme would also shift investment decisions in the power plant sector towards gas power plants with lower emission and greater flexibility.…”

Capacity payments to secure electricity supply? On the future of Germany’s power market design

Although the objectives of the Energiewende (energy transition) are broadly accepted in Germany, the practical ways of achieving them remain highly contentious. In particular, the question of whether and how security of supply can be guaranteed over the course of this profound transformation of the energy system is currently the subject of controversy in the scientific and public debate. Recently, calls for additional payments to power plant operators for providing generation capacity have grown increasingly loud. But the introduction of capacity payments of this sort could have far-reaching consequences for the future organisation of Germany's electricity supply. Therefore, the political decision on this issue-which is scheduled for this year-should not be made without a sound scientific analysis. Basically, measures aimed at guaranteeing security of supply must address the possible causes of capacity shortages as broadly as possible. When designing such measures, besides security of supply, additional objectives such as cost-effectiveness and the environmental and social acceptability of electricity supply should also be taken into account. Capacity payments only partially meet these requirements. Moreover, once introduced, they are difficult to adapt, or revise even, to suit changing framework conditions. This is particularly problematic in view of the current lack of clear evidence for future security of supply problems. Therefore, introducing capacity payments at this point in time would not appear to be constructive. It would make more sense to introduce instead a mix of measures which would strengthen the electricity market, create conditions for feeding in electricity from renewable energy sources as and when required, and set incentives for the expansion of grid capacity, storage systems and demand side management. Should security of supply still appear uncertain under these changed framework conditions, the introduction of a strategic reserve, which would be held by the regulatory authority or the transmission system operator, is recommended-not, however, the creation of an entirely new, additional market segment in the form of a capacity market.

“…At present, discussions about the instrumental implementation of this dimension of market integration focus primarily on competitive bidding processes, given that the new EU guidelines on state aid express a clear preference for this instrument type [4]. A further distinction is necessary between the market integration and system integration of RES -the latter aims at improving RES' contribution to grid stability [1,13] but is not the focus of this article.…”

“…On the other hand, however, critics question the usefulness of a direct marketing-driven integration of intermittent RES into the marginal cost-based electricity market, which may be structurally unsuitable to secure their long-term refinancing [18][19][20][21]. Furthermore, there are trade-offs between the objective of exposing RES producers to market price signals in order to increase the efficiency of production and investment decisions on the one hand, and the creation of a secure planning basis for RES investors, which is crucial to achieve a comprehensive transformation to an RES-based electricity system, on the other [13]. If RES producers carry a high share of market risks, this would also tend to increase the costs of supporting the implementation of RES objectives, because higher risks have to be compensated by higher risk premiums in the remuneration [22][23][24].…”

Market integration of renewable energies through direct marketing - lessons learned from the German market premium scheme

et al. 2015

Background: Increasing the market and system integration of renewable energy sources (RES) is regarded as key to reducing the costs of RES support and transforming the electricity system. In several EU countries, feed-in premium schemes have been implemented to better align RES production with electricity prices and to enhance the efficiency of RES marketing by increasing direct participation of producers in electricity markets. This paper examines the lessons learned from the German market premium scheme, which was introduced in the Renewable Energy Sources Act 2012 as an optional alternative to feed-in tariffs. The 2014 reform of that law has made direct marketing mandatory except for small RES plants, thus establishing the sliding market premium as the new primary instrument of RES support. Methods: Combining a qualitative economic analysis with insights from sociological research on direct marketing and simulation results from agent-based modelling, we evaluate how well the optional market premium has performed in setting incentives for demand-oriented RES production and efficient marketing of RES electricity. Furthermore, we examine what efficiency gains can be realistically expected from the changes implemented in 2014, and discuss whether the direct marketing model adopted in Germany is a promising approach for improving the market integration of RES. Results: We find that direct marketing has made a positive contribution to the marketing efficiency of dispatchable RES; for intermittent RES, it provides few structural changes compared to marketing through transmission system operators. The benefits of a greater demand-orientation of RES feed-in remain limited when considering the extent to which load shifting is incentivised. For intermittent RES in particular, incentives for demand-oriented feed-in are only effective in times of negative electricity prices when voluntary curtailment is encouraged.
