OMT - Overview
• Customer driven.
• Customer outages are georeferenced.
• Logically connected network.
• Outages are assessed and prioritized.
Geographically related
Electrically related
Prioritized by number and type of customers affected
OMT – Problems
• Relies on customers to report outages.
May or may not report outage.
Customer observations may be unreliable.
• Reactive versus proactive.
• Labor and time intensive analysis.
• Delay in analysis causes restoration delays.
• Verification of outage restoration.
AMI – Overview
• Automated Metering Infrastructure (AMI).
Two-way Automatic Communication System (TWACS).
• Remote meter reading.
• Allows for the “ping” of the meter.

Implementation - Technology
• Visual Studio .NET and C#
• Component-based Scalable Logical Architecture (CSLA .NET) by Rockford Lhotka - www.lhotka.net
• ArcObjects used to create custom trace routines to trace the GIS logical network.
• Service Oriented Architecture (SOA) - Command Request Framework
• TWACS hijacking
