EC3(11) Average Number of Forced Outages
| Performance Measure | 02/03 | 03/04 | 04/05 | 05/06 |
| Average Number of Forced Outages by Asset Class (Large / Strategic / Available Energy / Thermal) (targets) | N/A | 2.4 / 3.8 / | 2.2 /3.6 / | 2.1 / 3.5 / |
| Average Number of Forced Outages by Asset Class (Large / Strategic / Available Energy / Thermal) (actuals) | 2.76 / 3.4 / | 2.26 / 3.04 / | ||
| Definition | A large plant is a station with capacity greater than 200 MW (38 units). Strategic plants include multiple plants on a river system, all Vancouver Island Generating Stations, and generating stations required for ancillary services (25 units). Available energy stations are all stations that are not classed as large or strategic (16 units). Thermal plants (9 units). A forced outage is the count of generating unit outages due to equipment failure or other unplanned events. The intent of this measure is to track the reliability of a generating unit to produce electricity for as long as called upon to do so. Reliability is improved by reducing the number and duration of forced outages. | |||
| Variance Explanation | Average Number of Forced Outages is better than target. While it is still too early to establish a definitive correlation, the improved plant performance may be due to implementation of reliability centred maintenance practices beginning in 2000/2001. | |||
| Benchmark Comparison | Exact comparable benchmark data is not available. However, a recent summary of all benchmarking conducted for BC Hydro by Haddon Jackson and Associates since 1999 showed that all major generating stations performed in the top and upper-mid quartiles. | |||
