“…One component of the IPEG is the EEG levy, which aims to support the expansion of electricity generation from renewable sources. Based on the Renewable Energy Act (Erneuerbare Energie Gesetz, EEG), the collected EEG levies are distributed among the renewable power plant owners, for example as a market premium on the per-unit grid electricity feed-in [30]. In the case of PV systems, the electricity grid feed-in should be put on the market by a so-called direct marketer [30].…”

Aggregation of Households in Community Energy Systems: An Analysis from Actors’ and Market Perspectives

In decentralized energy systems, electricity generated and flexibility offered by households can be organized in the form of community energy systems. Business models, which enable this aggregation at the community level, will impact on the involved actors and the electricity market. For the case of Germany, in this paper different aggregation scenarios are analyzed from the perspective of actors and the market. The main components in these scenarios are the Community Energy Storage (CES) technology, the electricity tariff structure, and the aggregation goal. For this evaluation, a bottom-up community energy system model is presented, in which the households and retailer are the key actors. In our model, we distinguish between the households with inflexible electricity load and the flexible households that own a heat pump or Photovoltaic (PV) storage systems. By using a game-theoretic approach and modeling the interaction between the retailer and households as a Stackelberg game, a community real-time pricing structure is derived. To find the solution of the modeled Stackelberg game, a genetic algorithm is implemented. To analyze the impact of the aggregation scenarios on the electricity market, a “Market Alignment Indicator” is proposed. The results show that under the considered regulatory framework, the deployment of a CES can increase the retailer’s operational profits while improving the alignment of the community energy system with the signals from the electricity market. Depending on the aggregation goal of the retailer, the implementation of community real-time pricing could lead to a similar impact. Moreover, such a tariff structure can lead to financial benefits for flexible households.

“…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

et al. 2015

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.
