Beschrijving

The electricity market in Germany is likely to undergo several significant structural changes over the years to come. Here one may think of Germany’s ambitious renewable agenda, the disputed decommissioning of nuclear facilities, but also unbundling of TSOs as enforced by European regulation. This study is a scenario-based analysis of the impact of different realizations of known investment plans for transmission and generation capacity on the future German power market while accounting for internal congestion. For this analysis the static equilibrium model of the European electricity market COMPETES is deployed, including a 10-node representation of the German high-voltage grid. Results for the multi-node analysis indicate that price divergence and congestion are likely to arise in the German market as renewable additions affecting mainly the North of Germany, the debated decommissioning of nuclear facilities in the South, and the expected decommissioning
of coal-fired facilities in Western Germany appear to render current investment plans for transmission capacity insufficient. The current system of single-zone pricing for the German market may therewith be compromised. However, transmission additions would not benefit all market parties, with producers in exporting regions and consumers in importing regions being the main beneficiaries. Vertical unbundling of German power companies could increase the incentive for constructing transmission lines if generation capacity would cause Germany to be a net-importing country. In case Germany remains a net-exporting country, the effects of vertical unbundling on interconnector capacity are less clearcut.
