What This Utility Data Tells You

Alabama Power Co is an investor-owned utility operating in Alabama under EIA identifier 195. It reports service to approximately 1,537,035 customer accounts and generated about $6.16 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 Alabama Power Co customer experienced 302.3 minutes of power interruptions, a measure known as SAIDI, or System Average Interruption Duration Index. Excluding major weather events from that total, that falls inside the typical 120–180 minute national benchmark, in line with what most U.S. distribution utilities report. Over the same period, SAIFI (outage events per customer) was 1.50, putting the typical customer at roughly 1 distinct interruption that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 104.8 minutes; the difference from the headline 302.3 shows how much of the outage total came from weather rather than everyday grid issues.

With 4 consecutive years of EIA data (2020–2023), Alabama Power Co's reliability record can be judged on trend rather than one isolated year. SAIDI dropped from 1434.4 to 302.3 minutes across that span, a direction regulators and prospective customers tend to watch closely.
