In 2023, the average Town of Apex- (NC) customer experienced 80.0 minutes of power interruptions, a measure known as SAIDI, or System Average Interruption Duration Index. Excluding major weather events from that total, that is comfortably under the 120–180 minute national benchmark range, a sign of solid grid resilience and quick outage response. The SAIFI figure, which tracks average outage events per customer, came in at 0.66 for the same period, meaning customers statistically saw about 1 distinct interruption that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 37.0 minutes, the gap between that figure and the headline 80.0 reveals how much weather, not day-to-day infrastructure, drove outages.
Town of Apex- (NC) has 2 years of continuous EIA reporting on file (2022–2023), enough to read a real trend rather than a single-year snapshot. SAIDI has improved from 207.7 to 80.0 minutes over that window, a meaningful direction for prospective customers and regulators watching capital investment outcomes.
