Discussion of future challenges of supply security in the electricity market 2.0

It is questionable whether the current design of the electricity market will be able to guarantee the current level of supply security in the future. This is because the decline in conventional generation and the simultaneous expansion of supply-dependent renewable energies pose challenges for the market. This is the result of a new study commissioned by Zukunft Erdgas e.V. and carried out by the Institute of Energy Economics at the University of Cologne (EWI).

Starting Conditions for the Marketing of Demand Flexibility: Status Quo Analysis and Metastudy – 2nd version

This study by EWI, Fraunhofer FIT and FIM is part of the research project SynErgie which is funded by the German Federal Ministry of Education and Research for the enabling of the energy intensive industries in Germany to adapt the demand for electricity to the increasingly fluctuating supply of electricity. This study first describes the fundamentals of electricity market design and the legal framework. The reference to the application to industrial processes is always taken and potential barriers to the participation of flexible demand processes are worked through. The analysis serves the cluster-wide information about the status quo of market structures and regulatory framework conditions. In addition, the project partners analyze scientific findings on the subject of demand flexibility and prepare them in a comprehensive meta-study.

Short study: Flexibility potential of households for the network-related reduction of demand peaks

In future, increased use of heat pumps and electric cars in the building and transport sectors could create new requirements for network expansion and operation, especially in the low-voltage networks. The increased use of heat pumps and electric cars has an impact on the quantity of electricity demanded and on the temporal structure of electricity demand. Against this backdrop, the question arises as to which flexibility potentials could be used cost-effectively in households in the future.

In the context of this study, the flexibility potential of different household types is analysed. The focus here is on the costs of flexibility in time windows that are potentially critical for low-voltage grids. The study is based on the ewi ER&S model for the analysis of consumer behaviour (COMODO) and analyses the flexibility potentials for the year 2030.

Economic assessment of the market development model

To extend the current marketing possibilities for electricity from renewable energy sources, Bundesverband Windenergie (BWE) and ARGE Netz propose a market development model. This proposal of changing the Renewable Energy Sources Act (EEG) is supposed to allow a direct retail of renewable electricity from the plant operator to final consumers and at the same time to ensure the proof of the simultaneousness of generation and consumability. ewi ER&S analyses the economic effects of the market development model.
For final consumers, the model creates a possibility to show their preference – and thereby their willingness to pay – for consumable renewable power and to purchase it. This allows the plant operators a better marketing option of their consumable renewable power. If production and consumption happen spatially close to each other, this can additionally relieve the grids. The EEG account will not receive additional financial burdens, even reliefs are possible.
