Investigation Processes1. FIRE: Frequent Interrupters Requiring Evaluation
(kind of like a DEMI metric)1. Web‐based application that allows us to establish
thresholds for notification or2. If certain triggers are reached, an investigation is
required, which has a expected delivery date.1. Loss of supply investigation2. Lockout investigation3. CAIDI investigation

Investigation Processes2. Reliability Forum
1. If an outage gains management attention or raises concern of key participants, it can be nominated for investigation
2. Typically is the result of departments perceiving the events that took place differently.
3. Summary of findings is developed into structured document with “opportunities” specifically identified as well as what the possible reliability improvements were.

Investigation into device performance can be
performed by any FIRE user

FIRE: Links to Google Earth for virtual inspection
Local conditions of interrupting devices can also be looked at in map form to consider terrain,
exposure

FIRE: Shows device descending impact view
For regional performance and For regional performance and operating area assessment, individual devices can be
investigated to determine which are impacting the most customers and incurring the longest customer
interruptions

Reliability Forum• Data sources include recordings, logs, outage records, drawings and any relevant maps
• Are generally assigned to an operations manager, but recent assignments have been made to dispatch managers
• To date, approximately 30 forum investigations have been done
• Have broken through some organizational barriers• Have begun to build better fact finding skills across organization

Findings from certain analysis…Vehicle Interference
10
• Several large impact outages involved vehicle (and train) accidents
• Resulted in deeper mining for persistence of that specific outage trigger
• Findings were eye‐opening • Have resulted in pilot activities, including collaboration with transportation officials

Vehicle Interference: A Pilot Location & Device
Involved working with City Transportation officials, State DOT, etc.6 months later, pilot device placed (ice storms caused their own impacts to transporting device)

Vehicle Interference: How it stacks up geographically

Outage Investigation: The Moral of the Story
• Each person plays specific roles in outage investigations…leadership is one of the most important
• Figure out what their role can & should be & you’ll be golden
• Create mechanisms to make the investigation more streamlined
• When people investigate & come up with reasonable solutions, support that advancement
• Then the good ideas will start to snowball!
