RATIONALE FOR THE QUALITY OF SUPPLY POLICY; DETERMINATION OF QUALITY OF SUPPLY TARGETS

This paper describes how ENECO NetBeheer, a Dutch network company, determines its quality of supply targets and gives some insight how it is going to meet these. Quality of supply targets have been determined for HV, MV and LV networks related to several regions. To determine its quality of supply targets, ENECO NetBeheer has applied trend analyses, using a two years horizon to comply with the issue dates of its Quality & Capacity Document. Uncertainty has been indicated using confidence intervals. Targets have been decided and the remaining risk was estimated. To facilitate the development of measures to pursue the targets, performance indicators have been subdivided according to the type of faulted component and the causes of the initiating events. Improvement measures were focused on those causes that can be influenced by ENECO NetBeheer.
