New BER project "ARegV 3.0" to start in January 2019
The developments of Smart Grids alter the roles and responsibilities of distribution network operators (DNOs) and requires rethinking the regulatory framework, which in Germany is determined by the "Anreizregulierungsverordnung", in short "ARegV".
The most recent ARegV amendment offers additional incentives for network investments but lacks incentives for smartness. Thinking one step further, however, the question is how the conceptual development of regulation towards a future "ARegV 3.0" should look like. This research project analyses misaligned incentives for DNOs based on both a network model and a regulatory model and suggests further adjustments of the regulatory framework.

Marius Buchmann to chair session “Innovation in trading“ on "European Uititiy Week" in Vienna, Austria on November 11, 2018
Technological developments are drastically changing the energy trading industry. Technologies such as Blockchain, automated trading and Artificial intelligence will profoundly change what we recognize today as 'trading'. How will technology change trading? And what does the trader of the future look like? These are the key question that we will answer in this session. Marius Buchmann will open and host this session with presentations from Innogy innovation hub, econtrol, ponton, ark energy and others.

Presentation of Marius Buchmann on "The data management challenge for smart grids" on October 12, 2018.
"10th FSR – BNetzA Forum on the Legal Issues of Energy Regulation", Florence School of Regulation
Marius Buchmann presented his views on the current institutional/regulatory challenges that arise in the context of data management from smart metering and other smart home applications. What are the different data management models that are discussed for smart grids in Europe? How to address data monopolies? What do network and platform economies tell us when it comes to data platform markets? What will the future of data management look like? This and other issues were discussed in Berlin at the BNetzA on invitation from the Florence School of Regulation (FSR).

The Need for Competition between Decentralized Governance Approaches for Data Exchange in Smart Electricity Grids - Fiscal Federalism vs. Polycentric Governance
published in The Journal of Economic Behavior and Organization. Volume 139, 106-117
The institutional framework of the electricity sector is challenged by digitalization. With smart metering, data on energy consumption and production becomes available. Information management shall secure the efficient exchange of this data (e.g. from smart metering) in smart grids. Currently, national as well as regional governance approaches for information management systems are being developed. We discuss how the scale and scope of an information management system has an influence on the level of innovation in the process of the data exchange. We define information management as a club good and apply the insights from the theory of fiscal federalism. We conclude that neither of the extremes of national (central) and decentralized governance approaches for information management will be optimal. Rather, we identify the need of polycentric governance approaches that compete with each other to define the optimal degree of decentralization.
Xgen in der Anreizregulierung: Was kann der Malmquist-Index?
Gert Brunekreeft und Stephan Vaterlaus
published in Energiewirtschaftliche Tagesfragen , No. 3, 2017, 13-16.
Aktuell muss der generelle sektorale Produktivitätsfaktor (X-Faktor oder XGEN) für die dritte Regulierungsperiode der Anreizregulierung für Energienetze bestimmt werden. Dabei lässt die Anreizregulierungsverordnung (ARegV) bei der Bestimmung des XGEN die Verwendung von Unternehmensdaten zu, was in den Diskussionen in der Regel mit der sogenannten Malmquist-Methode in Verbindung gebracht wird. Die Frage stellt sich: Ist die Malmquist-Methode zur Bestimmung eines XGEN im regulatorischen Kontext überhaupt geeignet? In dem Aufsatz werden zwei wichtige Umsetzungsfragen in Bezug auf die Malmquist-Methode aufgegriffen. Zum einen diskutieren wir, welche Auswirkungen die Tatsache auf die Malmquist-Methode hat, dass die BNetzA nur über Gesamtkosten (TOTEX) verfügt. Zum anderen untersuchen wir auf Basis von Simulationen den Einfluss der Datenqualität auf die Robustheit der Malmquist-Ergebnisse.
Joint study of Jacobs University and Polynomics on the Malmquist Index as a means to calculate the general X-Factor for electricity distribution companies.
In German: "Die Ermittlung des technologischen Fortschritts anhand von Unternehmensdaten – Der Einsatz der Malmquist-Methode im deutschen Regulierungsrahmen"
In a joint research study, prepared for the German electricity distribution company NetzeBW, Polynomics and Jacobs University Bremen analyse the use of the Malmquist Index to calculate the general X-Factor (Xgen) for electricity distribution companies in the German regulatory framework. The Xgen needs to be calculated for the next regulatory period starting 2019; currently, the debate is about the method of calculation: Törnquist or Malmquist?
The final report of the study (in German) can be downloaded here.
BER study on the general X-Factor for electricity distribution companies in the face of energy transition.
"Die 3. Periode ARegV: Xgen und die Energiewende"
The general X-Factor (Xgen) as part of price-based regulation aims to capture total factor productivity (TFP) of the network business and ensure a fair distribution of efficiency gains between network companies and consumers.
The main conclusion is that the previous methodology and parameters may have worked fairly well in the past, but do not appear to provide adequate productivity indicators for the future. Given the fundamental structural changes of the energy transition, one should reconsider the “outputs” based on which the networks’ TFP is calculated.

"Distribution Planning and Pricing in View of Increasing Shares of Intermittent, Renewable Energy in Germany and Japan"
The purpose of this research is to evaluate the impact of increasing shares of intermittent, renewable energy in distribution grids. Our research mainly relies on in-depth interviews with sector-experts from German utilities. We discuss both effects in network planning and challenges for network pricing.
The results are now available as Bremen Energy Working Papers No. 20.
Joint research project on future decentralized power networks
"Collective non-linear dynamics of power networks (ConDyNet)"
The project analyzes the dynamics in newly arising complex, decentralized power networks. It is part of the initiative "futureproof networks" funded by the ministry for economic affairs and energy, and the ministry for education and research over a timespan of 3 years. Together with Potsdam Institute for Climate Impact Research, Max Planck Institute for Dynamics and Sefl-Organization, Frankfurt Institute for Advanced Studies and Jülich Research Center, we will model and simulate optimization options, critical network states and risk scenarios. The focus of Bremen Energy Research herein will be on the economic framework for such complex, decentralized networks; deploying agent-based computational economics to asses the influence of innovative pricing scemes on their operation and development.

Our research mainly relies on in-depth interviews with sector-experts from the German utilities. We will discuss both short-term changes and the long-term impact on competition in the electricity market as well as the impact on costs and security of supply.
The results are now available as Bremen Energy Working Papers No. 16.
Joint Study of Bremer Energie Institut and WU Wien

The aim of the project was to identify the key areas within the institutional framework of the electricity sector in Austria where adaptation is required to support the development of smart grids. To address these adjustment requirements we analysed best practises in other countries.
The results are now available at BMVIT Schriftenreihe nachhaltig wirtschaften 7/2014.
Jacobs University Study
"Prices and contracts in the German wholesale gas market"
Over the past few months, Jacobs researches belonging to the BER group performed a study where gas-purchasing strategies of German utility companies were analyzed. Within this study, 250 German gas utilities were addressed with a questionnaire about their gas purchasing strategies, historical price data from the last six years were analyzed, as well as interviews with gas market brokers and market price publishing institutions were performed.
The study was introduced to public in autumn 2013 and can be downloaded using the following link: Preis- und Vertragssituation im deutschen Gasmarkt.
