2013 Service Continuity Data on Distribution System Performance in Electrical Utilities
Composite, Non-Confidential
Electric Power System Reliability Assessment
INTRODUCTION This report presents the results of the fifty-first consecutive survey of the performance of the Distribution Systems in electrical utilities. The report, prepared by the Canadian Electricity Association (CEA), presents a statistical summary of the Distribution Systems Performance for the year 2013 and compares it to 2012, as well as to the 2009-2013 five-year average. The report presents some industry standard metrics for the Electricity Distribution including:
• System Average Interruption Frequency Index (SAIFI) • System Average Interruption Duration Index (SAIDI) • Customer Average Interruption Duration Index (CAIDI) • Index of Reliability (IOR) • Customer Interruptions per Kilometre (CIKM) • Customer Hours per Kilometre (CHIKM)
By using the above metrics in combination with the cause of an electricity interruption, utility companies can
• set targets for improvement • develop programs in support of their improvement targets • make design/build decisions that try to mitigate interruption causes
Members of the Service Continuity Committee and participants in the Service Continuity program follow a systematic procedure for collecting and analyzing data with regard to the Distribution System Performance according to definitions set by the Committee. This procedure follows the guidelines set out by CEA’s Electric Power System Reliability Assessment program (EPSRA) which governs system continuity statistics for the entire electricity system. This includes the statistics captured in this report for the Distribution system and also statistics captured in the Bulk Electric System (BES) for service interruptions within the Transmission system. The EPSRA program is governed by the Consultative Committee on Outage Statistics (CCOS). The CCOS Committee was chaired until early 2010 by Dr. Roy Billinton of the University of Saskatchewan, a world renowned expert in the field of Electricity Equipment and Systems Reliability. The mission and vision of the Service Continuity Committee is below: Mission: Provide a comprehensive database of component and system reliability and performance data which will assist member utilities in the optimal utilization of corporate and financial resources. Vision: To be recognized as a world-class reliability database which meets the needs of its member utilities. At the recommendation of the program participants, CCOS approved the creation of the Service Continuity Committee (SCC). The objectives of the SCC are:
• To add value to SCC members by providing a forum for Distribution System personnel to identify, develop and monitor the relevancy of key performance indicators and actively seek ones that provide a perspective on the continuity of electric supply to the customer
• To facilitate development of inter-utility networking for Distribution System reliability • To maintain, update and provide guidance on common definitions and terms used in service continuity
performance measurement consistent with Canadian and international utility practices • Provide guidance with respect to maintaining data integrity • Reporting to CEA’s Consultative Committee on Outage Statistics (CCOS) and supporting its overall
mandate of providing its members with relevant comparative reliability information together with a network of contacts to enhance performance
• Coordinate with other CEA groups such as the Distribution and Customer Councils The membership of SCC includes one member of each of the participating CEA Corporate member utilities. It is chaired by Tom Janzen of Fortis Alberta. The Vice-Chair is Lisa Gryba of EPCOR.

1.0 DEFINITIONS 1.1 DEFINITION OF TERMS DISTRIBUTION SYSTEM A Distribution System is that portion of an electric power system which links the Bulk Electricity System (BES) or sources with the customer's facilities. Subtransmission lines, distribution substations, primary feeders, distribution transformers, secondaries and customers’ services all form different parts of what can generally be called Distribution Systems. The Delivery Point (DP) is the delineation point between the BES and the Distribution System. It is the low voltage busbar of the step down transformer station, whereby the transformer busbar is considered part of the BES System. At the transformer station the voltage is stepped down from a transmission voltage, which may cover a range of 60-750kV to a distribution voltage of under 60kV. Where the reporting company does not own the equipment up to the Delivery Point as defined above, the delineation point shall be at the point of ownership. CUSTOMERS The average number of customers served in the region during the reporting period. This means the number of customer services fed at secondary, primary and subtransmission voltages. A customer is defined as a metered service. Municipal utilities buying power from Provincial utilities should not be reported as customers by the Provincial utility. INTERRUPTION An interruption is the loss of service to one or more customers and is the result of one or more component outages. A momentary interruption is defined as an interruption with a duration of less than one (1) minute. These are interruptions generally restored by automatic reclosure facilities, which are of a very short duration (on the order of a few seconds). INTERRUPTION-DURATION This is the period from the initiation of an interruption to a customer until service has been restored to that customer. INTERRUPTION START TIME
An interruption is deemed to have occurred when the utility supplying power is made aware that a customer is without power. This is either the time the customer calls in or the time remote monitoring devices indicate a power interruption. It may be for either a full or part power interruption.
INTERRUPTION END TIME
An interruption is deemed to have ended when the utility supplying power is made aware that a customer's power has been restored. This is either the time the restoring crew reports the restoration is complete or the time remote monitoring devices indicate a power has been restored. CUSTOMER-HOURS OF INTERRUPTION This is the product of the customer services interrupted by the period of interruption. CUSTOMER-INTERRUPTIONS This is the sum of products of the customer services interrupted by the number of interruptions that affect those customer services.

SYSTEM AVERAGE INTERRUPTION FREQUENCY INDEX (SAIFI)
This index is defined as the average number of interruptions per customer served per year.
SAIFI = Total Customer-Interruptions Total Customers Served
SYSTEM AVERAGE INTERRUPTION FREQUENCY INDEX (MOMENTARY) SAIFI (MI) This index is defined as the average number of interruptions per customer served per year for momentary
interruptions (interruptions of a duration less than 1 minute). SAIFI (MI) = Total Momentary Customer-Interruptions Total Customers Served (in area where momentary interruptions are monitored)
SYSTEM AVERAGE INTERRUPTION DURATION INDEX (SAIDI) This index is defined as the system average interruption duration for customers served per year. SAIDI = Total Customer-Hours of Interruptions Total Customers Served
CUSTOMER AVERAGE INTERRUPTION DURATION INDEX (CAIDI) This index is defined as the customer average interruption duration for customers interrupted during a
year. CAIDI = Total Customer-Hours of Interruptions Total Customer Interruptions
CUSTOMER INTERRUPTIONS PER KM Customer Interruptions per KM = Customer Interruptions Circuit Km
CUSTOMER HOURS PER KM Customer Hours per KM = Customer Hours Circuit Km
INDEX OF RELIABILITY The per unit of annual customer-hours that service is available. Index of Reliability = 8,760 hours/year - SAIDI 8,760 hours/year

1.2 CLASSIFICATION OF INTERRUPTIONS BY CAUSE
A customer interruption has been defined in terms of primary cause of the interruption. These causes have been assigned the following codes:
0 - Unknown
Customer interruptions with no apparent cause or reason which could have contributed to the outage.
1 - Scheduled Outage
Customer interruptions due to the disconnection at a selected time for the purpose of construction or preventive maintenance.
2 - Loss of Supply Customer interruptions due to problems in the bulk electricity supply system such as underfrequency load shedding, transmission system transients, or system frequency excursions. During a rotating load shedding cycle, the duration is the total outage time until normal operating conditions resume, while the number of customers affected is the average number of customers interrupted per rotating cycle.
3 - Tree Contacts
Customer interruptions caused by faults due to trees or tree limbs contacting energized circuits.
4 - Lightning
Customer interruptions due to lightning striking the Distribution System, resulting in an insulation breakdown and/or flashovers.
5 - Equipment Failure Customer interruptions resulting from equipment failures due to deterioration from age, incorrect maintenance, or imminent failures detected by maintenance.
6 - Adverse Weather
Customer interruptions resulting from rain, ice storms, snow, winds, extreme ambient temperatures, freezing fog, or frost and other extreme conditions.
7 - Adverse Environment
Customer interruptions due to equipment being subjected to abnormal environment such as salt spray, industrial contamination, humidity, corrosion, vibration, fire or flooding.
8 - Human Element
Customer interruptions due to the interface of the utility staff with the system such as incorrect records, incorrect use of equipment, incorrect construction or installation, incorrect protection settings, switching errors, commissioning errors, deliberate damage, or sabotage.
9 - Foreign Interference
Customer interruptions beyond the control of the utility such as birds, animals, vehicles, dig-ins, vandalism, sabotage and foreign objects.
