A new working paper by Smaranda Sgarciu, Daniel Scholz and Prof. Felix Müsgens on how carbon prices accelerate decarbonisation has been published

The paper, "How CO2 Prices Accelerate Decarbonisation - the Case of Coal-Fired Generation in Germany", compares two types of coal phase-out instruments. Namely i) direct regulatory intervention and ii) market-based CO2 pricing instruments. 

Some highlights are:
1. rising CO2 prices can make coal-fired generation unprofitable and thus accelerate the coal phase-out.
2. CO2 pricing instruments lead to a trade-off between accelerating the coal phase-out and accelerating the employment reduction in the coal sector.

Prof. Müsgens discusses the implications of the German dependency on Russian fuels in an interview for Märkische Allgemeine (MAZ)

In an interview for Märkische Allgemeine (MAZ) Prof. Müsgens discusses the dependency of Germany and Europe on Russian gas and oil, the future of lignite and the possibilities of saving energy.
In his opinion, regarding the expansion of sanctions against Russia, the West should focus on the issue of oil, since Russian revenues from oil exports are three times as high as those from gas exports. Also, Germany would more easily cope with a supply stop of Russian oil than a stop on gas supply.

A long version of the interview is available here, a short version here.

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).

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".
