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.
dena Smart Meter Study
"Implementation of Smart Meters in Germany"
The dena Smart Meter Study analyses the parameters influencing efficient and operative structuring of the rollout of intelligent meters and intelligent metering systems in Germany. In cooperation with eleven German electricity distribution grid operators or their affiliated metering station companies.
The final report of the dena Smart Meter Study is now available for download (in German language) on the website of Deutsche Energie-Agentur (dena).

"Unbundling of electricity transmission system operators in Germany – An experience report"
The purpose of this research is to evaluate the impact of vertical unbundling on German electric utilities. 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 Institutional Framework for Smart Grids in Austria"
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.
