What This Utility Data Tells You

Duke Energy Progress - (NC) is a investor-owned utility operating in North Carolina under EIA identifier 3046. It reports service to approximately 1,541,868 customer accounts and generated about $4.16 billion in annual electric revenue, with a service footprint spanning 500 ZIP codes. As an investor-owned utility, it operates under state public utility commission oversight that reviews rate cases and reliability performance.

In 2023, the average Duke Energy Progress - (NC) customer experienced 240.7 minutes of power interruptions — a metric called SAIDI (System Average Interruption Duration Index). That sits within the 120–180 minute national benchmark range, indicating performance typical of U.S. distribution utilities. SAIFI — the average number of outage events per customer — was 1.54 for the same period, so customers statistically faced roughly 2 distinct interruptions that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 145.6 minutes — the gap between that figure and the headline 240.7 reveals how much weather, not day-to-day infrastructure, drove outages.

The EIA dataset includes 4 years of continuous reporting (2020–2023) for Duke Energy Progress - (NC), which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI has improved from 429.3 to 240.7 minutes over that window — a meaningful direction for prospective customers and regulators watching capital investment outcomes. All figures on this page come directly from EIA Form 861, the federal annual electric power industry survey, with service territory ZIPs sourced from OpenEI — you can cross-reference them with your own utility bill or use them when comparing providers before relocating.
