Efficient integration of renewable energies with sector coupling technologies

Power-to-X technologies are important for the transformation and decarbonization of the energy system. In a project for German Federal Environment Agency (Umweltbundesamt), Consentec in cooperation with Fraunhofer ISI and the law firm Beiten Burkhardt investigated how the integration of renewable energy by means of sector coupling is efficiently designed with respect to regulatory and legal framework. Focus was on the qualitative and quantitative analysis of reform options for government-induced price components. In principle, the analyses show that there are no clearly preferable solutions but that trade-offs always play an important role. The final report and a detailed appendix are published on the website of Umweltbundesamt.



In 2019, Consentec supported the German TSOs in developing recommendations for enhancements to the German imbalance settlement. Consentec has now prepared a comparable expert opinion for the Austrian TSO APG. Based on the “Imbalance Settlement Harmonization Methodology” approved by ACER, the proposal developed provides for introducing an incentivizing and a scarcity component. These two elements are intended to ensure that, on the one hand, balance responsible parties will be able to reduce their imbalance costs, and on the other hand, situations endangering system security can be avoided. The methodology proposed will be consulted.

vzbv publishes study on proposed reforms for electricity network tariffs

There is vivid debate in Germany at present on how the flexibility of new consumption technologies like e-mobility chargers or heat pumps shall be made available for network-oriented purposes. The consumers association Verbraucherzentrale Bundesverband (vzbv) has commissioned Consentec to analyse different models and to develop recommendations on their appropriate design. Special focus was put on a model proposed by consultants of the Federal Ministry of Economic Affairs and Energy and on the option of introducing time-dependent use-of-network charges. vzbv has recently published this study.


Description of concepts for the German system balance and control reserve market

Commissioned by the German TSOs, Consentec prepared a description of concepts for the German system balance and control reserve market already in 2014, which was published on This explanatory document has been updated and supplemented in order to meet the requirements of Article 60.1 of the Guideline on Electricity Balancing (EB GL) The document (English version will soon be published) fulfills the requirement defined in the guideline that TSOs should prepare a report on the electricity balancing system for the previous two years at least every two years.


Agora’s study “Building sector Efficiency: A crucial Component of the Energy Transition” also available in English

Agora’s study “Building sector Efficiency: A crucial Component of the Energy Transition” which was published in 2018, is also available in English. In cooperation with the Institut für Energie- und Umweltforschung Heidelberg (ifeu) and Fraunhofer Institute for Energy Economics and Energy System Technology (IEE) Consentec analysed how climate targets can be achieved by building efficiency measures. To these ends, cross-sectoral effects of building efficiency measures and their impact on the total economic costs of heat-supply were presented. The study also identifies measures to take in buildings, energy systems and networks if energy-saving measures for buildings are not implemented.

Study on behalf of BMWi (Federal Ministry for Economic Affairs and Energy) on procurement of redispatch published

Consentec has conducted a study on how to procure redispatch. The study was on behalf of BMWi and conducted in cooperation with Neon and further partners. The key question was on cost- vs. market-based procurement of redispatch. Our main recommendation is to not introduce market-based redispatch: cost-based of course also has disadvantages (e.g. difficulties incorporating load flexibility, lack of regional investment signals), however market-based redispatch leads to an inconsistent market design. This would harm the functioning of the zonal electricity market (“EOM 2.0”) dramatically. The so-called Inc-Dec-Gaming is a major problem with market-based redispatch. Our findings and conclusions are now published in a final report of the study. Also results of quantitative analyses, of which Consentec was in charge, are published. These analyses show the practical relevance with regard to the problems of market-based redispatch.


Evolution of imbalance settlement price regime – German TSOs publish expert opinion by Consentec

During 2019 the transmission system operators have realized an increasing trend towards very high imbalances of the Grid Control Cooperation. For this reason, they commissioned Consentec to analyze the incentives resulting from the current imbalance settlement as well as to propose amendments to this regime. In this context any current and foreseeable economic development should be taken into account. The report identifies existing misleading incentives to balance responsible parties. A revised model on relationship between imbalance settlement and spot prices was proposed and is now publicly consulted.

Bundesnetzagentur publishes report on the regulatory treatment of distribution network operators’ costs

Energy transition has profoundly changed the requirements to electricity distribution networks. Meeting these challenges, network operators will have access to a wide range of innovative solutions, some of which significantly differ in their cost structures from conventional solutions. Commissioned by German regulator Bundesnetzagentur, Consentec - in cooperation with Frontier Economics - has investigated which kind of incentives the current regulatory framework provides to distribution network operators when selecting the most adequate solutions. Furthermore, the report examines how the incentive regulation regime could be enhanced in order to counteract possible distortions of incentives.


E.ON’s study on impacts of e-mobility

E.ON’s four distribution network operators have commissioned Consentec to analyze the impacts of e-mobility. By analyzing the expected consumption patterns caused by high penetration of e-mobility, fears of very high simultaneities could be rebutted. The subsequent simulation of grid expansion based on detailed models for medium and low voltage networks has proved that the volume of expansion will be feasible. Additional costs associated therewith will be comparatively manageable, even in the case of a 100 percent penetration. Furthermore, the study has quantified the benefits of potential charging control concepts. E.ON has presented the main findings of the study in a press briefing.


Study on Options of Improving the Electricity Network Tariff System published

The Federal Ministry for Economic Affairs and Energy (BMWi) has published the final reports on the study “Options of Improving the Electricity Network Tariff System in Germany to Support a Secure, Environmentally Sound and Economically Efficient Energy Transition”. In cooperation with Fraunhofer ISI, Consentec has examined current issues regarding incentive and cost-distribution effects of electricity network charges. On this basis, manifold options for improvement of the tariff system have been assessed with regard to their effects and feasibility. A separate report is dedicated to the expected development of network charges until 2030 for various types of network users in case the tariff system remains unchanged.


EC study on “Investment incentives in electricity and gas infrastructure in the EU”

The EU Commission has awarded a study contract to an international consortium with Consentec’s participation, aiming at analysing the national regulatory systems for electricity and gas TSOs with regard to their incentive properties for investments in innovation and security of supply. In addition to interviews with network operators and regulatory authorities, we are conducting a short survey in order to seek the view of further interested stakeholders. Interested organisations and individuals are cordially invited to participate in the survey under this link.
