Taimyra Batz and Prof. Felix Müsgens have published an article in the Journal Energy Policy about the evaluation of the German solar auction program.

In this study, the authors present an algorithm to overcome data limitations regarding the publication of individual bid information by combining four publicly available databases. The algorithm is applied to the German solar auction programme allowing the evaluation of auctions using quantitative methods. They calculate realisation rates and—using correlation and regression analysis—explore the impact of PV module prices, competition, and project and developer characteristics on project realisation and bid values. The results confirm that the German auctions were effective. The authors also found that project realisation took, on average, 1.5 years (with 28% of projects finished late and incurring a financial penalty), nearly half of projects changed location before completion (again, incurring a financial penalty) and small and inexperienced developers could successfully participate in auctions.

Structural change in the energy industry in Lusatia

On June 30, 2021, Prof. Felix Müsgens discussed the new opportunities arising from the energy transition and structural change in the Lausatia region in a presentation for jalta.consultants e.V. 

The energy transition aims to reduce greenhouse gas emissions. In the process, the energy system is being changed from the ground up. Generation from centralized large-scale power plants using fossil fuels is being replaced by decentralized plants that produce electricity depending on the weather. Lusatia, with its focus on electricity generation, is particularly affected by this development. In this context, the presentation discusses the new academic and economic opportunities for students and entrepreneurs.

Potsdam Science Days #PTDW

In the context of the the Potsdam Science Days (3-9 May), the Brandenburg University of Technology Cottbus-Senftenberg has been present with several contributions, including Prof. Müsgens presentation on the energy transition in Germany and its effects in Europe.

Prof. Müsgens and Prof. Antweiler have published an academic paper “On the long-term merit order effect of renewable energies” in the journal Energy Economics.

Using a stylized electricity market model, the authors analyze market equilibria under different levels of renwable energy. In the short-term the merit order effect is unambiguously negative: adding RES lowers prices. However, in the long-term, the merit order effect is zero – assuming base load remains in the system and competition is perfect. 
The paper was mainly written while Prof. Müsgens was visiting professor at UBC Sauder School of Business, hosted by his co-author Werner Werner Antweiler.

Iegor Riepin and Prof. Felix Müsgens have published a research article on "Seasonal Flexibility in the European Natural Gas Market" in The Energy Journal

The authors focus on seasonal demand swings in the European natural gas market. They quantify the role of different flexibility options (domestic production, gas storage, and pipeline and LNG imports) that are used to cover European demand fluctuations. This work contributes to the existing literature on seasonal flexibility by addressing the problem with a mathematical gas market optimization model. The paper provides valuable empirical insights into the decline of gas production in northwestern Europe. Furthermore, the authors propose a new metric to quantify the importance of supply sources for seasonal flexibility provision.

Why is Germany’s energy transition so expensive?

This is the question Thorsten Engelhorn and Prof. Müsgens answer in their latest paper  "Why is Germany’s energy transition so expensive? Quantifying the costs of wind-energy decentralization" published in Resource and Energy Economics.

Some of their conclusions include:

  • Variations in (annual average) wind speeds are high even within countries. 
  • One argument in favor of building a strong transmission grid for electricity: it allows using the best wind sites. 
  • In the period from 2000 to 2015, the same annual amount of electricity from wind energy in Germany could have been produced at lower costs for turbines (saving up to 30%), lower land use (saving also up to 30%) and significantly less installed turbines (up to 40% less).

Article published: Modelling uncertainty in coupled electricity and gas systems—is it worth the effort?

We are excited to share news that Iegor Riepin, Thomas Möbius and Felix Müsgens published an article on „Modelling uncertainty in coupled electricity and gas systems—is it worth the effort?” in Applied Energy journal. The authors study a trade-off effect between the complexity and precision arising from combining an optimization problem for the integrated electricity and gas system models and stochastic optimization techniques useful to capture multiple uncertainties existing in both systems. The authors analyze and compare the impact of uncertain factors, such as gas and electricity demand, renewable energy capacities and fuel and CO2 prices, on the quality of the solution obtained in the integrated optimization problem. Thus, the paper quantifies the value of encoding uncertainty as a part of an integrated energy system model. Such methodological contribution will be of interest for energy modelers, while findings of the paper are relevant for industry experts and stakeholders with an empirical interest in the European energy markets.

Research results on market design from the Academies’ project ESYS have been published

The energy transition is progressing, but the electricity market design is lagging behind. With the shift towards climate-friendly alternatives in transportation and heating, the demand for green electricity is growing. In this context, the promotion of wind and solar energy as well as the efforts to expand the grid are not enough. The academy project “Energy Systems of the Future” (in German „Energiesysteme der Zukunft“), in which Prof. Müsgens and Prof. Hartmut Weyer (Clausthal University of Technology) lead the working group “Electricity Market Design”, presents two proposals for a new market design that promotes sector coupling and effectively manages network congestion.

The statement "Pricing CO2, restructuring taxes and side payments" poses the question how a stronger integration of the electricity, heating and transport sectors can contribute to the greening of the overall system. Prof. Müsgens explains: “If the income from CO2 pricing is used to reduce taxes and levies that burden low-emission electricity generation, a twofold benefit can be achieved. First, the CO2 pricing corrects the externality of greenhouse gas emissions, which also means that climate-friendly technologies benefit. Second, it generates an income that can be used to relieve the burden of companies facing international competition and private households."

The final presentation on the topic "Pricing CO2, restructuring taxes and side payments" can be found under the following Youtube-Link.

Articel published in Nature Energy

Felix Müsgens and Iegor Riepin just published an article on „Offshore wind competitiveness in mature markets without subsidy” in Nature Energy. After 18 month of research collaboration with an international team of scientists, we are excited to share our results.

The article analyses the results of 17 auctions for offshore wind energy in five European countries with a total of 41 accepted wind farms. As the auction designs vary considerably over time and between countries, the results were harmonized and converted into an average revenue per MWhel.

Our results suggest that we are approaching a subsidy-free era for offshore wind. Furthermore, we spot the first offshore wind farms that not only can be operated without subsidies but will probably even pay money back over lifetime for the right to produce electricity, i.e. receive "negative subsidies".

Digital, decentralized, international? The energy system of the future

Im November 2019 war Prof. Felix Müsgens als Co-Leiter der AG Strommarktdesign innerhalb des Akademienprojekts „Energiesysteme der Zukunft“ (ESYS) Podiumsteilnehmer bei der Jahresveranstaltung 2019. Die im Berliner Futurium ausgerichtete Diskussion drehte sich vor allem um Fragestellungen zur Digitalisierung und Flexibilität eines künftigen treibhausgasneutralen Energiesystems. Zusammen mit Jutta Hanson (Technische Universität Darmstadt) und  Christoph Mayer (OFFIS – Institut für Informatik) diskutierte Prof. Müsgens entsprechende Herausforderungen, u. a. auch das möglichst effiziente Management von Engpässen im Stromnetz. Die gute Nachricht: Da erneuerbare Energien zunehmend wettbewerbsfähig werden, können sie verstärkt in den Bereichen Wärme und Verkehr eingesetzt werden. Um diese Sektorenkopplung weiter voranzubringen, müssten alle Energieträger in einen offenen Wettbewerb miteinander treten. Die im Klimapaket der Bundesregierung beschlossene CO2-Bepreisung sollte dafür das zentrale Instrument sein.
