Generation System Performance

The Generation System Availability and the Generation System Forced Outage Rate are updated once a month. These values only related to Centrally Dispatched Generation Units (CDGU).  The Generation System Availability values and the Generation System Forced Outage Rate for the past 3 years and this year to date are available below, along with a brief explanation of each.

1. System Generation Availability

This is calculated on a rolling 52-week basis. For example, the Generation System Availability for week 52 of 2004 is equal to the sum of the weekly availability for week 52 plus the preceding 51 weeks divided by 52. The weekly availability for each week is calculated as the sum of available centrally dispatched generation units divided by the total installed capacity of the centrally dispatched generation units.

2. System Generation Forced Outage Rate

The Generation System Forced Outage Rate is also calculated on a 52-week rolling basis and is calculated as the sum of the weekly forced outage rates for the previous 52 weeks divided by 52. The weekly forced outage rate for each week is calculated as the sum of the forced outages experienced by the centrally dispatched generation units during that week divided by the total installed capacity of the centrally dispatched generation units.
