Supply reliability refers to the trouble-free operation of network components and networks as a whole, and is assessed by metering the average frequency and duration of supply interruptions. The reliability indicators that can be calculated form these data also enable international comparisons of supply reliability.
Definition in the technical and organisational rules
Part A of the technical and organisational rules defines supply reliability as “the ability of an electrical system to fulfil its tasks under certain conditions during a predefined period of time.”
E-Control’s contribution to supply reliability Since 2002, E-Control has been monitoring supply reliability in accordance with the Statistik-Verordnung (Statistics Ordinance). We cooperate with the system operators and with the Association of Austrian Electricity Companies and publish the results of our monitoring exercises annually. They confirm that Austria enjoys a high level of supply reliability.
