32. Customer Satisfaction -Reliability Indices
SAID – System wide outage duration
Outages affecting major circuit backbones
CAID – Customer average outage duration
Outages affecting specific customers through lateral taps – localized storms, animal, and equipment failures
SAIF – System wide outage frequency
Number of outages experienced by system

33. Reliability Indices Industry Standard Measures from Y2000/2005

40. Conclusion
The Division received APPA’s RP3 Platinum Award (score of 98/100) on May 21, 2008 for its Reliability, Safety, and System Improvement programs. Electric Division has improved system performance since 1995 through employee commitments in positive work ethics, acceptance of new division procedures and policies, technical and customer service training, system ownership, increased productivity, and excellent design and maintenance standards.
ITS GOOD TO BE MORE THAN YOU ARTURNED ON TURNED OFF!
Narrative
We continue to make great strides toward improved reliability. Again, it is important to understand that we are still in the early stages of the Big Picture. We will continue to work consistent with our new policy procedure and standards always respecting safety as #1. The key to customer satisfaction is system reliability. The Planning Studies addresses system reliability which begets Customer Satisfaction.
