What the allocation would fetch at one auction's price. Utilities consign part of their allowances to these auctions and must return the proceeds to customers; the rest they hold for compliance or bank.
Allocated to “Avista” on Ecology’s schedule, filed as investor-owned utility. A utility cannot sell these allowances to another company: it uses them for compliance, banks them, transfers them to an eligible generator, or consigns them to a quarterly auction, and the proceeds must go back to customers.

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.
ID · IEEE 1366EIA-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 ↗
Customer programmes
EIA-861 Schedule 6, as filed
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
Reported by the utility on EIA-861 Schedule 6 Part A as adjusted gross savings at the customer meter under its own evaluation; figures are not comparable across utilities. Reporting-year incremental savings are annualized for participants new that year; life-cycle savings run over the programmes' planned life (energy as a lump sum, peak as the average annual reduction). Each class is shown as filed and the total row is the filer's own; nothing is summed here. Costs are nominal dollars of the report year (the form collects thousands; PUDL publishes dollars). A blank stays blank.
Report year 2024, ID, WA. Each row is one customer class as filed; the filer's total is its own line and is not the sum of the rows above. Costs are nominal dollars.

ModeledComputed billsA declared usage case priced on a published tariff sheet: kWh in one bill, the days it covers, and where the sheet has them a service size, dwelling type or jurisdiction and a season. The total is the schedule's own charges: the fixed charge plus the energy charge by tier. Where the same sheet prints prices for named adjustments or credits, a second, separately labelled total adds them; those prices change on their own schedules. Whatever the sheet only names, such as a city tax, is listed and never added, so neither total is a complete bill. It is an illustration, not a billing record, and it is not the realized average revenue per kWh that EIA-861 reports.Definition ↗ for 3 declared cases. Prices are the sheet’s own; usage and days are assumptions.

Schedule 63· Net Metering Option Schedule· effective 2024-05-17
Excess kilowatt-hours are credited on following bills and reduce those bills; on 31 March each year any credit accumulated during the previous year is granted to the company without compensation. Systems are capped at 100 kW AC and meter aggregation follows RCW 80.60.030
Substitute fourth revision of Sheet 63; Schedule 65 carries the interconnection standards.Source ↗read 2026-09-18
The price on the utility's own sheet on the date it was read, with the adjustment schedules it names listed beside it and never added in. It is not a bill, and it is not the realized average revenue per kWh that EIA-861 reports above: the two answer different questions.
Distributed generationCustomer-sited and small generation reported by utilities in aggregate on EIA-861; no locations; a separate population from the plant inventory, never added to it.Definition ↗
Utility reports · no locations
Distributed generation reported by this utility to EIA-861 for 2024, by state
Utility-reported, no locations, not in the EIA-860 plant inventory (>= 1 MW). Storage is listed separately and never added to generation capacity. Non-net-metered units >= 1 MW can also appear in EIA-860; the overlap is disclosed, not resolved. Source rollup rows are excluded from every sum.
Sum of EIA-861 utility-reported nameplate capacity over leaf technology classes, excluding storage and source rollup rows; utility x state grain; no locations; not part of the EIA-860 plant inventory

HIFLD segments Avista’s layer does not fully cover
The HIFLD copy the atlas carries holds lines at 100 kV and above only; HIFLD's full compilation carries some of the lines it lacks under 100 kV. A covered segment is not shown to be the same line: parallel lines in one corridor are closer than 150 m.
Show Avista’s lines beside HIFLD on the map ↗The map draws each segment by the voltage Avista files, in the classes and filter it uses for BPA's and HIFLD's lines; a segment filed with no voltage (de-energized, or a code its layer does not name in kV) is drawn as "Voltage not stated". Its tiles carry nothing else but the line and tap name (decision 72): status and the comparison are counted here, not drawn.
Proximity, not identity: a segment within 150 m of a HIFLD line is not shown to be the same line, and parallel lines in one corridor are closer than that.
Nothing is replaced: the utility's segments and HIFLD's stay drawn side by side; HIFLD's carry its owner, voltage and date, the utility's are counted here by the voltage it files.
No capacity, rating, circuit, connectivity or ownership share is stated by either source; a line beside a plant or project is not an interconnection.
The utility's own line layer as its public maps draw it at retrieval, beside the HIFLD 2021 segments the atlas carries. Lengths are drawn geometry measured in the CONUS Albers projection: a sum of segments, not route, circuit or conductor length.

Washington State Legislature (RCW 19.405, RCW 19.285), Washington Utilities and Transportation Commission orders and docket filings, Washington State Department of Commerce EIA and CEIP report summaries, and each utility's own filings, cited per row
One assertion per row, five kinds kept apart: what applies, what is owed, what the utility filed, what the issuing body decided, and the open proceeding. A fuel-mix value is not a compliance verdict, and a filing that restates a target does not enact it; standing on each row says whose figure it is. An absent row states what was checked and when; a utility not in the file has not been curated.
Display names and aliases (pipeline/config/crosswalks/aliases.csv)

A display name is the name an organization uses for itself; the EIA name stays searchable and on the record. Each row cites the page that shows the name.
