MidAmerican Energy Co

What This Utility Data Tells You

MidAmerican Energy Co is an investor-owned utility operating in Iowa under EIA identifier 12341. It reports service to approximately 729,757 customer accounts and generated about $2.13 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 MidAmerican Energy Co customer experienced 80.0 minutes of power interruptions, a measure known as SAIDI, or System Average Interruption Duration Index. That keeps this utility below the typical 120–180 minute national benchmark, consistent with a well-hardened distribution system and fast restoration crews. The SAIFI figure, which tracks average outage events per customer, came in at 0.83 for the same period, meaning customers statistically saw about 1 distinct interruption that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 59.0 minutes, the gap between that figure and the headline 80.0 reveals how much weather, not day-to-day infrastructure, drove outages.

MidAmerican Energy Co has 4 years of continuous EIA reporting on file (2020–2023), enough to read a real trend rather than a single-year snapshot. SAIDI has improved from 1004.0 to 80.0 minutes over that window, a meaningful direction for prospective customers and regulators watching capital investment outcomes. Note: this figure is unusually low compared to typical U.S. utility performance and may reflect an incomplete EIA filing for this year rather than a genuine reliability improvement -- treat with caution and cross-check against MidAmerican Energy Co's other reported years.
