Direct Customer Impacts

27

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

28

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

34

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
