In this paper, CEER explores how the relationship and regulatory arrangements between DSOs and TSOs may need to evolve to ensure that efficient system solutions (either conventional or new) can be deployed to accommodate the needs of a sustainable energy system. The paper puts forward specific principles which CEER believes should set the trajectory of the future DSO-TSO relationship and related regulatory arrangements in the areas of governance arrangements, network planning and system operation.
This is the final report for the pan European efficiency benchmarking of gas transmission system operations commissioned by the Netherlands Authority for Consumers and Markets (ACM), Den Haag, on behalf of the Council of European Energy Regulators (CEER) under the supervision of the authors: project team leaders professors Per AGRELL and Peter BOGETOFT from SUMICSID and Urs TRINKNER from Swiss Economics.
The project acronym is E2GAS (Economic Efficiency analysis of GAS transmission operators). The report is open. No part of the final report has been formally reviewed by the Commissionaires and expresses only the viewpoint of the authors, who exclusively bear the responsibility for any possible errors.
The views have not been adopted or in any way approved by CEER and should not be relied upon as a statement of CEER´s views. CEER does not guarantee the accuracy of the information given in the study, nor does it accept responsibility for any use made thereof.
Citizen's Q&A CEER Status Reviews provide an overview of the status of implementation of the DSO and TSO unbundling provisions set out in the EU's "3rd Energy Package". Under this Package the energy networks are subject to unbundling requirements, which oblige Member States to ensure appropriate separation of networks from generation/supply activities, in order to protect the energy consumer.
This report provides a general overview of the regulatory regimes, the required efficiency developments and analyses the overall determination of capital costs in EU Member States and Norway. A major focus is placed on the calculation of an adequate rate of return, the determination of the regulatory asset base (RAB) and the depreciation of assets in the different regulatory regimes. Importantly, individual parameters presented in this study have to be interpreted in the context of a whole country-specific regulatory regime. The data collection, covering investments in 2015, took place in summer 2015.
The Council of European Energy Regulators (CEER) brings together Europe’s independent energy regulators allowing them collectively to play a major role in developing and delivering the Internal Energy Market alongside their significant contributions to the work of the Agency of the Cooperation of Energy Regulators (ACER). CEER also supports the work of the European institutions and seeks to foster good regulatory practices with consumer interests at their heart.
