What short-outage Cheyenne Light Fuel & Power filings show
Cheyenne Light Fuel & Power is an investor-owned utility operating in Wyoming under EIA identifier 3461. It reports service to approximately 44,789 customer accounts and generated about $0.20 billion in annual electric revenue, with a service footprint spanning 14 ZIP codes. Investor ownership puts this utility under the regulatory authority of the state public utility commission, which reviews its rate requests and reliability record.
In 2023, the average Cheyenne Light Fuel & Power customer experienced 71.9 minutes of power interruptions, a measure known as SAIDI, or System Average Interruption Duration Index. Excluding major weather events from that total, that places this utility well below the 120–180 minute national benchmark, signaling strong grid hardening and fast restoration practices. SAIFI, the average number of outage events per customer, was 1.05 for the same period, so customers statistically faced roughly 1 distinct interruption that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 35.4 minutes, the gap between that figure and the headline 71.9 reveals how much weather, not day-to-day infrastructure, drove outages.
Cheyenne Light Fuel & Power has 4 years of continuous EIA reporting on file (2020–2023), enough to read a real trend rather than a single-year snapshot. SAIDI has improved from 272.2 to 71.9 minutes over that window, a meaningful direction for prospective customers and regulators watching capital investment outcomes.
Based on this utility's own EIA Form 861 reliability record -- baseline (major-event- excluded) outage duration, total outage duration, and outage frequency -- each benchmarked against every reporting utility nationwide. Not a measure of electricity rates or customer service, which this portal does not track.
