Analysis of Performance

Fort Collins Light & Power reliability in one sentence: 

On average, a customer in Fort Collins can expect a 48 minute outage about every four years.

  • SAIDI is how long, on average, each customer was without power in the last year.
  • The 20Q3 SAIDI number improved to 10.82 minutes from 17.22 minutes in 20Q2. 
  • Taking into context SAIDI, CAIDI and SAIFI, reliability shows some overall improvement with a decrease in both duration and frequency of outages.  The decrease in frequency and customer-hours out is primarily because of a reduction in equipment failures. 

Metric Definition
The electric distribution System Average Interruption Duration Index (SAIDI) is a description of the length of time all customers would have been out of power if the total number of hours out of service in a year's time were to be shared, and it is typically measured in minutes. The number of outages as well as the time between the start of an outage and the restoration of electric service have a bearing on this number.
Why Is This Important?
SAIDI provides our customers with a sense of how well Fort Collins Utilities responds to outages.  Because SAIDI is an industry standard measure, it allows current and perspective customers to compare our quality of service to other communities.
City Organization Impact on Performance

High – Reliable electric service depends on quality installation and maintenance of utility infrastructure to avoid service interruptions and sufficient resources to respond quickly to outages as they occur.  Fort Collins Light and Power is directly responsible for both of these tasks.
