SAIDISystem Average Interruption Duration Index: the minutes of sustained interruption the average customer had over the year, customer-minutes interrupted divided by customers served. Each utility calculates and reports its own figure on EIA-861 Schedule 3, under the method it declares. A system average says nothing about one address.Definition ↗, SAIFISystem Average Interruption Frequency Index: how many sustained interruptions the average customer had over the year, customers interrupted divided by customers served, as the utility reports it on EIA-861 Schedule 3.Definition ↗ and CAIDICustomer Average Interruption Duration Index: minutes per sustained interruption, SAIDI divided by SAIFI on the same basis. EIA-861 asks utilities for SAIDI and SAIFI only; EIA publishes CAIDI with the data and the atlas shows it as published, never recomputed.Definition ↗ count sustained interruptions. Figures with and without major event daysDays a utility sets apart from normal operation: EIA describes them as events such as snowstorms, floods or heatwaves, or periods of outages that differ greatly from the utility's own five-year history. EIA-861 asks for the indices both with and without them. Part B respondents determine them under IEEE 1366; Part C respondents define a major event themselves. The two series answer different questions and are never blended.Definition ↗ are different measures; compare like with like.

OR · Other methodEIA-861 Schedule 3 has two parts. Part B is for utilities that calculate SAIDI and SAIFI and determine major event days under IEEE 1366-2003 or IEEE 1366-2012; Part C is for any other method, where the utility also states how it defines a momentary interruption and whether inactive accounts count as customers. Figures from the two parts are not comparable and the atlas never pools them; utilities under Part C do not share one method either.Definition ↗

Reported by the utility on EIA-861 Schedule 3 under the method it declares. IEEE 1366 and other-method figures are not comparable, and values with and without major event days answer different questions. A system average says nothing about one address. CAIDI is published by EIA as SAIDI divided by SAIFI; it is not a line on the form. A value the utility left blank stays blank. Source and licence· Frozen facts for this utility ↗

Programme results as each utility filed them, by customer class and report year, each in its own unit. Classes are never added into a total, years are never added into a period, and savings are never divided by sales. The one ratio shown, enrolled demand-response customers against the utility's own EIA-861 customer count for the same state, class and year, carries both counts.

Energy efficiency EIA-861 Schedule 6 Part A

A long-form filer with no Schedule 6 row: either no programme, or a separate administrator reports it.

Demand response EIA-861 Schedule 6 Part B

Reported by the utility on EIA-861 Schedule 6 Part B. Potential peak savings assume every programme is called; actual peak savings are what was achieved at the company's own annual peak hour, and the two are never merged. Customers are enrolled customers, a count. Costs are nominal dollars of the report year. The form has no total row and none is computed here. A blank stays blank.

Population: organizations of this release with EIA-861 rows in the core states. A short-form respondent has no figures to file; a long-form respondent without a row may have no programmes or may have a nonutility administrator reporting for it. Years without a row are listed against the table's span, not against the years this utility filed the form.
