Development of distribution outage and interruption reporting system on the intranet to facilitate asset management

Tenaga Nasional Berhad (TNB) embarked on a project to review the existing distribution outage and interruption reporting system on the intranet (known as TOMS - TNB Outage Management System) with the view to include the following major attributes/objectives.: 1) To align reporting methods and terms used to international standards. 2) To make use of utility-wide databases on assets, customer billing and information as the sources for identifying affected components and customer counts. 3) To improve customer service and supply reliability in the light of evolving industry drivers that include performance-based regulation, guaranteed service levels, e-business economy, deregulation, competition, highly publicized outage events and enhanced customer awareness. 4) To apply the asset management concepts of FMECA/FMEA in identifying outage modes and causes. 5) To review reliability index calculations in line with internationally accepted standards. 6) To establish applications of the outage database for reliability-based and risk-based network planning.
