New publication on energy-efficient behavior in the workplace published

Do messages to employees help and how should they be formulated to fund energy-efficient behavior in the workplace?

Christin Hoffmann and Kirsten Thommes have investigated this and published their findings in their latest publication "Can leaders motivate employees' energy-efficient behavior with thoughtful communication?" in the internationally renowned "Journal of Environmental Economics and Management".
The focus was on the effects of an employer's communication on the energy-efficient behavior of a company's employees. Christin and Kirsten found that messages with this purpose are generally worthwhile. With the help of natural language processing tools, the effects of positive and negative emotions, collective or individual focus and the complexity of the language were also analyzed.

Using a large test group of truck drivers as an example, the authors compared the daily energy efficiency after receiving a message with the daily performance without a previous message. They found that messages generally increased energy-efficient behavior. In addition, messages that conveyed positive emotions and emphasized a collective orientation were more successful. Sending a message showed significant effects on driver performance for up to six days afterwards, leading to economically relevant cost reductions. In our case, messages led to an overall saving of 0.5l of fuel per 100km.

New flagship publication on European hydrogen infrastructure planning published!

Our latest analysis looks at the future of European hydrogen infrastructure planning and focuses on hydrogen and green chemical energy carriers such as ammonia (NH3), liquid hydrogen (LH2), methanol (MeOH), liquid methane (LCH4) and Fischer-Tropsch diesel (FTD).

Important findings from our study are:

1️⃣ Significant cost reductions in green energy sources are expected between 2030 and 2050, which will have a significant impact on European Energy Economics.

2️⃣ Ammonia (NH3) will become a major player for hydrogen expansion due to its dual role as a hydrogen carrier and for direct consumption.

3️⃣ The low-cost sourcing from countries such as Chile, Egypt and Morocco highlights the global dimension of the European energy transition and emphasizes the importance of international cooperation.

Our findings underline the importance of innovation and strategic investment in research and development to accelerate the transition to a sustainable energy landscape. The focus on NH3 opens up new avenues for policy and investment that are in line with EU climate goals. This focus highlights the diversity of energy sources and the need for a nuanced approach to energy transition efforts. This analysis is part of the TransHyDE flagship report, which provides the latest research findings for European hydrogen infrastructure planning. You can access the full article here:

New working paper published: The impact of biogas plants on the real estate market

We are pleased to present the latest working paper of the EECON | Energy Economics Lab entitled "Smells like Green Energy - Quasi-Experimental Evidence on the Impact of Bioenergy Production on Residential Property Values"

Together with Christin Hoffmann, Shanmukha Srinivas Byrukuri Gangadhar and Felix Muesgens, we dive into the relationship between bioenergy production and property values and gain recent insights into the public acceptance of renewable energy.

The research used an improved difference-in-difference methodology that provides richer insights compared to traditional two-way fixed effects analysis. As a key finding, the study shows a significant negative impact of bioenergy production on property values, with this impact decreasing with increasing distance to the annex (0.5 km to 3 km). In particular, medium-sized bioenergy plants show a strong negative impact on real estate prices.Gaseous biogas plants have a significant negative impact on real estate prices compared to solid or liquid bioenergy plants, with this impact decreasing with increasing distance.

German Offshore Wind Energy Auctions: Competition and Challenges

In an interview with the newspaper Frankfurter Allgemeine, Prof. Felix Muesgens and Prof. Axel Ockenfels provided valuable insights into offshore wind energy

When it comes to restructuring the German electricity industry, policymakers rarely rely on the market. Too often, they get lost in a thicket of regulations and subsidies, miss their targets and drive up electricity prices for consumers. Occasionally, however, competitive elements come into play. One of these is purchasing auctions for renewable electricity: whoever offers the cheapest green power wins the bid. 
The latest success of the competitive process was seen in the recent wind offshore tenders in Germany. The rights to build 7,000 MW of offshore wind power were sold for €12.6 billion. Mind you, these are not subsidies for wind power, but payments by the companies for the right to produce offshore wind power. The grid connection is paid for by the state. The revenues from the auction are used to finance the grid connection, relieve the burden on electricity customers and protect the marine environment as best as possible. 

Despite this good news, there are voices who, in view of the surprisingly high price bids, want to change the tender rules and push competition back again. In particular, according to the proposal, the maximum level of auction prices should be limited in the future. The fear behind this is that wind power producers could demand high electricity prices on the wholesale market in response to high auction prices, so that their revenues are high enough to pay the auction price. However, this argument not only contradicts the logic of business management (companies do not seek to maximize profits only when costs are high), but is also based on a misunderstanding of how competitive electricity markets work (already "sunk" investment costs, which include auction expenses, do not play a role in price formation). More likely than rising wholesale prices as a result of the tender is that the additional feed-in from the new wind turbines will cause the wholesale price to fall in many hours. In addition, given the high revenues, it is conceivable that policymakers will now bring more offshore wind sites to the market more quickly and more often. Another argument against auction pricing is that the winning bidders may have been too optimistic in their assumptions (at least more optimistic than the losing bidders) and therefore their price bids were 'inflated' in the tender. This phenomenon is sometimes referred to as the 'winner's curse' and can indeed lead to problematic auction results. However, it is also true that investors can miscalculate in virtually any investment decision, from buying mobile spectrum in the telecommunications sector to buying stocks for retirement. Even if the state wanted to protect investors from such investment risks, a price cap in the auctions would be inappropriate for this purpose. The state cannot assess the market value of wind licenses any better than the companies. If it were otherwise, it would not need an auction to set the price and could instead set the selling price directly. Moreover, it remains unclear how the government should ration wind licenses if demand exceeds supply when the price cap is reached. In any case, a lottery or complex individual negotiations with suppliers are not attractive alternatives, as they may weaken competition, lead to inefficient allocation, increase electricity costs, and lead to increased lobbying.

Investors in power generation capacities are best protected by a stable and reliable energy policy. Risks, e.g. with regard to future electricity price developments, can be hedged on the electricity market. If the state wanted to assume the entrepreneurial risks (for which there are few reasons here), instruments suitable for competition would also be available for this, e.g. indexing auction payments to future electricity prices.
 However, there is also justified criticism. In wind auctions, the winners have to make only a small payment to the government compared to the size of the project if it is abandoned. But if the winners can get rid of their obligations at relatively low cost, financially strong bidders might see this as an invitation to consider wind licenses as an option rather than an obligation to build wind turbines: Only if the business and political conditions develop positively will investments then actually be made. As a result of auction obligations that are not very reliable, there is an increased risk that plants will not be realized and national climate plans will be put in jeopardy. Only recently, the Swedish utility Vattenfall announced its withdrawal from the development of the Norfolk Boreas offshore wind project with a capacity of more than 1,000 megawatts off the British coast, justifying this with the increased construction costs. However, these and other criticisms should not lead us to question competitive pricing altogether, as they can be addressed through smart auction design.

Our latest publication in the Journal of Hydrogen Energy: "Supply costs of green chemical energy carriers at the European border: A Meta-analysis

The paper overview, 

  • a meta-analysis of 30 studies, providing a detailed database on supply costs and parametric assumptions.
  • Our projections show that supply costs for all energy carriers could vary by 4x in 2030 and by 5x in 2050, primarily driven by production costs.
  • Significant parameters for production costs were identified as the weighted average costs of capital and capital expenditures of electrolyzers and conversion.
  • Transport costs were found to have a significant dependence on the choice of energy carrier and the weighted average costs of capital.

Scientific Advisory & Project Board meeting with the topic "Green base load for industry needs electricity storage".

As part of a preliminary study commissioned by the transmission system operator 50Hertz, the results on the topic of "Green base load for industry" were presented by the BTU Cottbus-Senftenberg and the Fraunhofer Institute for Energy Infrastructures and Geothermal Energy. This was done during the Scientific Advisory & Project Board meeting on June 21, 2023. 50 Hertz spoke to various companies for the study. The tenor was clear: there is a high level of interest in the topic of "green base load". A crucial point for the companies is that the geographical areas from which the renewable electricity comes are not too narrow when implementing such a project. This increases flexibility and resilience, for example against storms," emphasizes Prof. Dr. Felix Müsgens from BTU Cottbus-Senftenberg.

The key findings of the study are:

  • Aggregate RE capacity between 6.3 MW and 7.6 MW is needed to provide 1 MW of green baseload. Short- and long-term storage technologies, as well as sector coupling technologies, play a critical role in limiting the overbuilding of needed renewable generation capacity.
  • The cost of 10 cents/kWh is achievable with a renewable share between 90-95% of electricity.

International Energy Economics Conference 2023 (IEWT) in Vienna.

During a presentation at the International Energy Economics Conference 2023 (IEWT) in Vienna Prof. Müsgens spoke about the effects of the Ukraine war in the energy market. While the war will have a positive long-term impact on climate protection and the energy transition, in the short term, negative consequences of the conflict are still to be expected. The energy transition will be completed more quickly as a result of the event. On the one hand,  natura gas has lost its importance as a bridging technology and on the other, the acceptance of renewable energies and their expansion has risen sharply.

The FOCCSI 2 project is a three-year research project funded by the Federal Ministry of Economics and Climate Protection (BMWK). 
In the project, we will develop "meta-forecasts" for both PV and wind feed-in based on weighted combinations of individual forecasts using AI and ML methods. The proposed methodology will be applied based on PV and Wind forecasts provided by TenneT data. 

New publication in Energy Policy on how CO2 prices accelerate decarbonisation in Germany

Our new article “How CO2 prices accelerate decarbonisation – The case of coal-fired generation in Germany” provides new insights on how different instruments to reduce carbon emissions impact the development of coal phase-out. We compare instruments to reduce emissions and their impact in the German market. We find that with current CO2 prices, more coal may leave the system than regulation foresees. As a consequence, market forces may reduce employment even faster than planned in the regulation.

New publication on wind energy auctions in Germany

Some highlights from the publication "Evaluating the German onshore wind auction programme: An analysis based on individual bids" published in EnergyPolicy's special issue on "Renewable energy auctions - past, present, and future":

- Realisation rates have been low so far – below 50% of awarded projects have been built.
- Secondary objectives (such as acteur diversity) are difficult to translate into design elements, making them even more difficult to achieve.
- A lack of competition has played a major role in keeping subsidy levels high.
- The auction design has reinforced the advantages of large developers.

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.

Hydrogen supply becomes a reality in the Lausitz

The news outlet RBB covers the plans for future green hydrogen station in the Lausitz. Prof. Müsgens gives a short comment on the importance of hydrogen in the energy transition.

You can access the video 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.

Is the coal phase-out coming sooner than expected?

The news outlet RBB reports on LEAG's decision to adjust its plans for the coal phase-out in Cottbus. The company plans to produce even less coal than expected, which could lead to an earlier exit. Prof. Müsgens comments on this decision and talks about the difficulties for coal-fired power plants to remain profitable at current and projected energy prices.

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).
