Electric System Average Interruption Duration Index (SAIDI) in Minutes
Analysis of Performance
Fort Collins Light & Power reliability in one sentence: On average, a customer in Fort Collins can expect a 10.57-minute outage every year.
SAIDI is how long, on average, each customer was without power in the last year.
The Q2-25 SAIDI value increased slightly to 10.57 minutes from 11.57 minutes compared to the 12-month measurement period for Q1-25.
Taking into context SAIFI, SAIDI, and CAIDI Q2-25 reliability showed a similar frequency of outages (60 outages versus last quarter's 71), and a decrease of 1,288 overall customer outage hours (14,195 hours versus last quarter’s 15,483 hours) for the 12-month, measurement period for Q2. But, for those customers who experienced an outage, the average outage time increased from 44.44 minutes to 49.89 minutes.
The slight decrease in customer hours for outages is viewed as very minor from the previous quarter, with 21 primary cable failures, 2 - 200-amp Multi-Position Junction, 15 - Single Phase transformers, 3 - 200-amp standoff junctions, 11 transformers, and 1-600 amp splice, with the remaining outage hours all being associated with secondary service connections and cable.
