Company Evaluates Reliability Performance At a Variety of Levels

Reliability Process: Is Based on Time & Location• Daily comparison against device, cause

code, duration thresholds are performed…FIRE web-based notification tool

• Periodic review to determine those which are not operating reliably or experiencing deteriorating trends

1) Tabular data reviewed: circuit metrics, including weighted blended score

2) Graphic data reviewed, including geospatial

• Evaluated by operations, engineering, maintenance and vegetation personnel

• Implement plans that are developed and monitor their delivery

• Review results & modify plan as needed

Location

Time

Reliability Programs: Many tools in the toolbox• Fuse It or Lose It (FIOLI)-circuit

coordination program• Saving SAIDI-circuit hardening program,

which could include animal guard installations, hot-spot vegetation treatment

• Network Initiatives-capital circuit enhancement, generally recloser installation, substation relay replacement

• Pilot Programs-evaluating new products or processes for implementation, i.e. spacer cable, TripSavers and Fusesavers (tapline reclosing devices)

• FIRE web-based threshold notification process

• Faulted circuit indicator installation• Circuit infrared inspection• Substation relay instantaneous trip settings

2) A DESCRIPTION OF THEIR CURRENT DISTRIBUTION SYSTEM MAINTENANCE PROGRAMS


PacifiCorp’s Distribution Maintenance Programs Include both Preventive and Corrective Components

Preventive Maintenanceinspect facilities, identify abnormal conditions, and perform appropriate preventive actionsTransmission and Distribution Lines Performed in accordance with General Orders 95, 128 and 165. Patrol inspections are designed to identify damage or defects that may endanger public safety or

adversely affect the integrity of the electric system. Detailed inspections are in depth visual inspections of each structure and the spans between each

structure or pad-mounted distribution equipment. Pole intrusive testing includes a sound and bore to identify decay pockets that would compromise

the wood pole’s structural integrity.Substations and Major Equipment Performed in accordance with General Order 174. Pacific Power inspects and maintains substations and associated equipment to ascertain all

components within the substation are operating as expected. Abnormal conditions that are identified are prioritized for repair (corrective maintenance).

Pacific Power has a condition based maintenance program for substation equipment Protection system and communication system maintenance performed on a time interval basis.

PacifiCorp’s Distribution Maintenance Programs Include both Preventive and Corrective Components

Corrective MaintenancePrimary focus of the corrective maintenance plan is to correct the abnormal conditions found during the preventive maintenance processTransmission and Distribution Lines Correctable conditions are identified through the preventive maintenance process. Outstanding conditions are recorded in a database and remain until corrected. Priority of conditions establishes corrective timeframes and General Orders (as appropriate).• Substations and Major Equipment Correctable conditions are identified through the preventive maintenance process, often

associated with actions performed on major equipment. Corrections consist of repairing equipment or responding to a failed condition.

PacifiCorp’s Distribution Maintenance Programs Wisdom is Incorporated into Reliability Planning

Basic PremiseMany safety code non-conformities do not result in reliability issues, however certain of them have a higher likelihood of resulting in poorer reliability As a result, inspection results are reviewed when performing reliability

planning and when investigating repetitive device operations. Geospatial tool overlays inspection conditions onto circuit topology

(GREATER). Device operation tool (FIRE) associates inspection conditions with zones of

protection of the circuit. May be corrective immediately or queued up for annual planning process.

1) Review condition comments and evaluate their probability of causing any reliability

issues…2) Select conditions of interest

3) Press View Conditions in PowermapTip…if you want to organize by map string use the

Reliability Tools: Geospatial Overlay of Inspection Conditions with Reliability Performance

3) A DESCRIPTION OF THE DATA AND METHODOLOGY THEY USE TO IDENTIFY POOR PERFORMING CIRCUITS AND ANY SOLUTIONS USED TO RESTORE PERFORMANCE TO ACCEPTABLE LEVELS


Reliability Programs: Many measures to discern opportunities to improve reliability

• Industry benchmarks• Company and district level comparisons• Time based comparisons• Circuit level performance• Blended circuit metrics (i.e. circuit

performance index)CPI = Index * ((SAIDI * WF * NF) + (SAIFI * WF * NF) + (MAIFIE * WF * NF) + (Lockouts * WF * NF))Index: 10.645SAIDI: Weighting Factor 0.30, Normalizing Factor 0.029SAIFI: Weighting Factor 0.30, Normalizing Factor 2.439MAIFIE: Weighting Factor 0.20, Normalizing Factor 0.70

Lockouts: Weighting Factor 0.20, Normalizing Factor 2.00Therefore, 10.645 * ((3-year SAIDI * 0.30 * 0.029) + (3-year SAIFI * 0.30 * 2.439) + (3-year MAIFIE* 0.20 * 0.70) + (3-year breaker lockouts * 0.20 * 2.00)) = CPI Score

• Customer metrics (i.e CEMI, RPI)

Reliability Process: Output from Review ProcessCrescent City

carry over from 2014:- no outstanding work.

FIRE tasks etc.:- 5r171/170 high impacting, lots of loss of

supply- 5r165 t/r from trees- 5r152 planned and vehicle accident,

equipment failure, no actionable

2015 Plans:- 5r165:

- look into relocating recloser to south branch at FP304701 and add trip saver to east.

- recloser will require more poles and reconfiguration.

- other option is to install fault indicators at the pole where it splits.

- need a fault indicator on south side of 100T fuse to indicate where to isolate, at FP057901

- 5r167:- install ~6,300 ft

spacer cable between FP142300 and FP227102
