Transco exceeds service quality targets
PANGASINAN (3 April) -- The National Transmission Corporation (TransCo) has surpassed its 2006 performance target for service quality and reliability as shown by marked improvements in its key operational indices.
A national report released by TransCo through District III headed by Engr. Jose R. Arellano, showed that Transco's improved service quality indicators include the internationally recognized Sustained Average Interruption Frequency Index (SAIFI) or the total number of times a customer experiences power interruptions in a year; Sustained Average Interruption Duration Index (SAIDI) or the length of time in hours of power interruptions that a customer experiences in a year; and Unsaved Energy(UE) or the amount of energy a customer was not able to use due to power interruptions.
Records presented at TransCo's 2006 Year-end Review show that the corporation has steadily improved its SAIFI, SAIDI and UE levels since 2003, the year Transco started operating separately from the National Power Corporation.
"Being a utility firm, we are aware of the rising expectations of our customers. We remain committed to continuously raise the bar of our performance," says TransCo president and CEO Arthur N. Aguilar.
The SAIFI and SAIDI indicators gauge the quality of power delivery to TransCo customers in terms of the reliability of the transmission network. Less frequent and shorter power fluctuations or interruptions that hamper power customer's activities translate to more reliable electricity service.
TransCo registered 0.5 customer interruptions (SAIFI) in 2006, a 36.6% improvement from its target of 0.82. In 2003, it was 0.98. A lower SAIFI means lesser number of times that a customer is out of power due to Transco caused outages.
SAIDI level in 2006 was at 0.40 hour,18% better than the 0.49 hour target for the year. The 2003 SAIDI level was 1.47 hours. This was reduced to just 0.49 hour by 2005. A lower SAIDI indicates that TransCo is able to restore transmission service after a power interruption within a shorter time period.
Meanwhile, in terms of System Availability (SA) or the time that major components of the transmission system such as lines, breakers and transformers are available, TransCo registered consistently high 99% availability since 2003. Through the years, TransCo has been improving the reliability of the grid through rehabilitation of transmission lines and substations, the addition of moraines and the upgrading of transmission capacities.
