What This Utility Data Tells You
Nevada Power Co is an investor-owned utility operating in Nevada under EIA identifier 13407. It reports service to approximately 1,014,976 customer accounts and generated about $3.03 billion in annual electric revenue, with a service footprint spanning 118 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 Nevada Power Co customer experienced 72.0 minutes of power interruptions, a metric called SAIDI (System Average Interruption Duration Index). That places this utility well below the 120–180 minute national benchmark, signaling strong grid hardening and fast restoration practices. Over the same period, SAIFI (outage events per customer) was 0.62, putting the typical customer at roughly 1 distinct interruption that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 53.7 minutes, the gap between that figure and the headline 72.0 reveals how much weather, not day-to-day infrastructure, drove outages.
Nevada Power Co has 4 years of continuous EIA reporting on file (2020–2023), enough to read a real trend rather than a single-year snapshot. Over that span, SAIDI rose from 52.2 to 72.0 minutes, possibly reflecting tougher weather years or grid upgrades that have not caught up yet.
