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). The 25 highest of 27 filings are drawn; the price table above carries every figure. Median across 27 South Carolina filings: 733.2 minutes with major event days, 103.3 without. EIA's state total: 3,136.5 and 117.8 minutes, with SAIFI of 2.37 interruptions per customer. Utilities use differing calculation methods, and a single storm can dominate a small utility's year.
