Regulatory framework Performance standards

Performance standards

Refers  to  the  level of quality  a  company  (or  a  group  of companies) is expected and/or required to provide. The definition of performance standards must take into account conditions that are inhe rent to each system ( i.e., topology, weather phenomena, etc. ) and can sough to be achieved gradually over time.

Even  though  quality  indicators  and  performance  standards  are  most  commonly reported and  tracked  at  an  aggregate  or  average  level  (i.e. , annual  SAIDI  of  a company, average SAIDI in a country, etc.), they can also be specified for groups of end users depending on their importance or prioritization. For example, a SAIDI indicator  or  30  hour s  for  a distributor means , that  on  average,  a  client  will experience 30 hours of electricity supply interruptions within a year, however, the average value most probably conceals the fact that there are a set of customers that  experience supply  interruptions  totaling  way  over 30  hours in  the  year . The previous example reveals that even though a distributor can on average improve its  quality  indicators, it  is  not  necessarily  making  improvements  for  the  users experiencing the worst service quality within the network.

To  cope  with  th is issue ,  the  concept s of individual  quality and worst - served customer (customers whose service quality is below a certain threshold relative to the average service quality ), may be used . P erformance standards can therefore be set a t an individual level or for a group of customers. Service quality monitoring and  analyses  must consequently be  done  at  a  much  lower  disaggregation  level (i.e. , circuit level)
