This report updates some of the interruption data contained in CEER’s 6th Benchmarking Report (in 2016). This report includes newer data on continuity of supply in electricity, and the technical operational quality of gas and some new ways to present the data such as aggregated box-plot summary graphs. The main indicators covered in this report include:
• System Average Interruption Duration Index (SAIDI)
• System Average Interruption Frequency Index (SAIFI)
• Customer Average Interruption Duration Index (CAIDI)

This CEER Conclusions Paper on Incentives Schemes for Regulating Distribution System Operators (DSOs), including for innovation is the result of a public consultation, a workshop in April 2017 and CEER’s own deliberations on the topic in light of the input received. The paper addresses the changing needs and aims of regulation, which are driven by ongoing market developments and the energy transition. The paper focuses on 4 aspects of regulation:
- the changing aims of regulation
- approaches of good practice on the balancing of regulatory choices
- innovation and
- steps to reach an optimal outcome for the whole system.
This CEER Conclusions Paper lists the main goals that regulators should pursue in their regulation of DSO regulation, including 10 key recommendations for creating optimal incentives schemes, particularly for the encouragement of innovation. Advocating a “whole system approach”, requires the DSOs to look at the societal net benefits for the whole system, rather than the impacts only on their own grid.
An annex to the document contains an evaluation of responses to the public consultation.

This document presents CEER report on investment conditions 2017 in European countries. High quality regulation is a fundamental requirement for a sound investment climate, which, in itself, is a pre-requisite for an adequate flow of the new investments needed to develop secure, competitive and sustainable energy infrastructure and markets. Predictable independent regulation also helps to reduce regulatory and legal risks for investors, and hence lowers the cost of capital. This report provides a general overview of the regulatory regimes applied in 2017, 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. Other important, individual parameters and new incentive mechanisms presented in this study have to be interpreted in the context of a whole country-specific regulatory regime. Some figures only reflect an ex ante approach for 2017, while ex post calculations still are to be executed. This report also serves as a background paper to CEER work on incentives, both in a quantitative as in a qualitative way.
