Direct Customer Impacts

The fallen tree caused a fault on Concord 406 serving three 12kv distribution substations East Brainerd (EBR), Jenkins Road (JEN) and Pine Ridge (PIN).

46KV Circuit & 12KV Substations Affected

6:51:09 PM 11,258 customers lose power
30
6:51:37 PM Service restored to 10,000 customers
Before the 46kv breaker completed the reclose cycle, the distribution automation sensed the loss of voltage, automatically opened and closed switches to reroute power from adjacent 12kv lines.
31
6:51:52 PM Service restored to another 800 customers
As the 46kv breaker completes the reclose
cycle and locks out, the 46kv automation
identifies the fault location, then opens
and closes switches to energize two of the
three stations.
32
6:55:04 PM Service restored to 289 customers
A dispatcher opens the PIN 201 breaker and
closes the first PCR on the PIN 201 circuit.
The 289 customers between these two
points now have electric power service.
33
6:57:47 PM All service restored
A dispatcher now opens the PIN 202
breaker and closes the first PCR on the PIN
202 circuit.
The remaining customers between
these two points now have electric power
service.
All electric services restored

Summary January 14, 2013 Storm
• 11,258 customers lost power due to a tree falling from outside of a right-of-way
• All customers restored through automation or remote operation within 6 minutes and 38 seconds
• Minimum number of switching operations required to restore service: 44
• Mileage between switches: 315
• Restored to normal through automation
• Without automation several hours of manual switching would have been required to restore service
