Quality of service
The quality of service provided by REN, understood in terms of security
and continuous supply of electrical energy with the necessary technical
characteristics, once again reached a high level, maintaining and consolidating a
trend observed in previous years towards a gradual and sustained improvement
in the performance of the National Transmission Grid (RNT).
The figures recorded by three (ENS, EIT and SARI) of the five general indicators
for service continuity established in the Quality of Service Regulations, were the
second best ever, thereby placing REN on a level with the world’s best companies
in a similar field. The remaining two indicators (SAI FI and SAIDI ) recorded the
third best figures ever. The Equivalent Interruption Time (EIT), an indicator of
overall performance commonly used by electrical utility firms, was 5.4 seconds,
the second best figure ever, equivalent to energy not supplied of 8.6MWh. That
is to say, REN fed electrical energy to the various consumer delivery points
99.99998% of the time (almost 999 hours, 59 minutes and 59 seconds, for every
1 000 hours).
