Analysis of Performance
Fort Collins Light & Power reliability in one sentence (SAIDI is how long, on average, each customer was without power in the last year):
On average, a customer in Fort Collins can expect a 58 minute outage about every 2.9 years.
- The 21Q3 SAIDI value of 19.34 minutes increased from 14.63 minutes in the prior quarter.
- Taken into context with each other, SAIDI, CAIDI and SAIFI, describe a more complete picture of reliability. 21Q3 reliability was reduced overall with increase in frequency and a small reduction in duration of outages.
- The increased frequency of outages was driven by dig-in outages. Dig-in failures are occurring as a result of an increase of excavation and directional drilling as part of the broadband deployment.
- The change in duration (customer-hours out) is primarily a function of the type of equipment failures that occurred in the 12-month period ending 21Q1. The prominent equipment failure types (medium voltage cables and connectors) were substantially the same as in Q2, so the drop in duration was not enough to improve reliability in light of the increased frequency of outages.
Why Is This Important?
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.
