Duke Energy Progress - (NC) is an 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. 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 Duke Energy Progress - (NC) customer experienced 240.7 minutes of power interruptions, a measure known as SAIDI, or System Average Interruption Duration Index. That sits within the 120–180 minute national benchmark range, indicating performance typical of U.S. distribution utilities. The SAIFI figure, which tracks average outage events per customer, came in at 1.54 for the same period, meaning customers statistically saw about 2 distinct interruptions that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 145.6 minutes; the difference from the headline 240.7 shows how much of the outage total came from weather rather than everyday grid issues.
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.
