Fort Collins Light & Power reliability in one sentence: On average, a customer in Fort Collins can expect a 13.67-minute outage every year.
SAIDI is how long, on average, each customer was without power in the last year.
The 24Q1 SAIDI value decreased to 13.76 minutes from 19.87minutes compared to the 12-month measurement period for 23Q4.
Taken into context SAIFI, SAIDI, and CAIDI 24Q1 reliability showed a similar frequency of outages (120 outages versus last quarter's 119), and a reduction of 18,788 overall customer outage hours (18,175 hours versus last quarter’s 36,963 hours) for the 12-month measurement period for Q1.
