Analysis of Performance

Fort Collins Light & Power reliability in one sentence: On average, a customer in Fort Collins can expect a 71.87 minute outage about every 3.33 years.

SAIDI is how long, on average, each customer was without power in the last year.

The 23Q3 SAIDI value of decreased to 21.86 minutes from 30.62 minutes compered to the 12-month measurement period for 23Q2.

Taken into context SAIDI, CAIDI and SAIFI, 23Q1 reliability showed an overall improvement with a decrease in frequency of outages (126 outages versus last quarter's 141), and a reduction of 11,443 overall customer outage hours for the 12-month measurement period for Q3. For those customers who experienced an outage, however, the average outage time increased from 68.46 minutes to 71.87.

The reduction in customer hours for outages is consistent with the transition from Summer and Fall to the winter months, with fourteen primary cable failures and one splice failure accounting for most of the outage hours.

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 over the last 12 months 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.
