| Title | Interruption indexes |
| Project Number | 22110 |
| Abstract/Scope | This Technical Report provides guidance on how to calculate continuity of supply indices. These recommended indices are more particularly given for European benchmarking of distribution network performance. For transmission network performance, more representative indices ) may be used. It presents – an overview of practices in Europe on long and short interruptions, – definition of physical interruptions in a harmonized way, – philosophy and criteria for recommending indices, – a suggested common approach to continuity indices. The fact that the networks in different parts of any particular country will be subject to different conditions (e.g. weather and customer density) mean that it is not viable to apply common performance standards to all networks within any one country or any group of countries without making these targets so weak that there is a good prospect of them being achieved in all areas. The present situation where national regulators set performance targets within their own countries is widely regarded as being the most effective mechanism for achieving optimal socio-economic performance. For these reasons this Technical Report does not provide common targets for the number and duration of interruptions that should not be exceeded. This Technical Report is designed to be a first step towards benchmarking the interruption performance of European countries. Rules on the aggregation of interruptions, in particular short interruptions, have not been considered in this Technical Report, however it is recognised that it might be necessary to describe aggregation rules in a second version of the Technical Report. |

| Normative reference (6) |
(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved
(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat
(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level
(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement
(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn
(6) This list of normative references is purely indicative. The only official list of normative reference is the list of the published standard.
