Average price is revenue divided by sales for the sector and year; it is not a tariff rate. Reliability figures are as reported by utilities to EIA on Form 861 and may use different calculation methods. State averages are EIA's own, from Forms EIA-861 and EIA-861M.

SAIDI: minutes of sustained interruption per customer over the year, including major event days (paler bars: the utility reported only the figure without major event days). Median across 19 Iowa filings: 85.7 minutes with major event days, 70.5 without. EIA's state total: 166.7 and 89.8 minutes, with SAIFI of 1.15 interruptions per customer. Utilities use differing calculation methods, and a single storm can dominate a small utility's year.
