On the residential bill 2026 rates · Residential Service, flat rate, effective 2026-01-01, in the utility’s own words
Where BPA's costs and benefits reach this utility's residential bill, in the utility's own documents: each clause that carries them into the sheet's charges, cited to the document that sets it, a price only where the utility prints one, and what no document states. The account's BPA dollars are never divided by revenue or sales to make a share of a bill.
Automatic BPA cost adjustment“If BPA implements new rates for power and/or transmission services, the updated BPA contract cost under the new rates for the subsequent 12-month period shall be compared with the Department's cost assumption used in the adopted revenue requirement for the same time period. If the calculated difference is more than $1.5 million, then it will be deemed material and passed through in rates. Within three months after the BPA rate implementation, energy charges in all rate schedules will be adjusted upwards or downwards by a consistent fixed per-kWh amount such that the identified material cost difference, including taxes, is collected from or credited to customers over the subsequent 12-month period from the onset of the rate adjustment.” In force until January 1, 2027, when Section 10 of Ordinance 127473 (passed 2026-07-21, approved 2026-07-22) repeals it (Section 15); the ordinance's recital moves BPA cost uncertainty into the expanded Rate Stabilization Account mechanism. A pass-through moves every per-kWh charge and has no line or price of its own: Ordinance 127122 records one effective 2024-01-01 that 'increased all per kWh charges by 0.12 cents per kWh' (recital, PDF p. 2), and the 2025 Financial Statements' unaudited rate notes say a 1.01% BPA passthrough 'is being applied to all retail energy charges beginning January 1, 2024' (page 93).

An entitlement is not a delivery and neither is a payment: an RHWM or CHWM in MWa caps what may be bought at the Tier 1 rate, a CDQ in kW is a monthly demand amount, a net requirement is load less resources, and dollars are what the utility reports it paid. None is added to, subtracted from or divided by another.
BPA's fiscal year runs October to September, a rate period is several fiscal years, the utility reports calendar years, and the Provider of Choice CHWM governs a contract period that has not begun. Figures of different periods are shown with their periods and never compared as if they covered the same time.
The product changed on the dates in the history: a figure names the products in force during its period, and one that spans a change says so.
Where the utility's note splits a year's BPA row into Block and Slice rows, each is a component of that year's purchase, not a product bought on its own: shown beneath the year's row, never added to it and never priced per MWh.
Credits from BPA (refunds, true-ups, reserve distributions) are quoted on the years the utility ties them to its BPA cost. None is netted, added or allocated, so a year's price per MWh is the utility's expense over its energy, including whatever it netted, and not a rate BPA charged.
The Fuel Mix Disclosure's BPA megawatt-hours are Commerce's attribution of the utility's Washington retail sales to BPA's system mix. They sit beside these figures and are not delivered energy, and they are not reconciled with BPA's quantities or the utility's dollars.
A price per MWh is derived only where the utility publishes its BPA energy in MWh for the same period in the same document as the dollars. An average in MWa is shown as printed and never multiplied by hours into MWh.
No cost is modeled from BPA's rate schedules: rates times these quantities would be an estimate, not a published figure.

Clean-energy obligationsFive separate records of a clean-energy obligation, never merged: applicability (which statute reaches this utility and why), target (the figure as enacted or ordered, or as a filing or compilation restates it, with that standing marked), filed achievement (what the utility itself reported for a period), determination (what the issuing body decided about the filing, with its order number and date) and deciding event (the open proceeding, its next step and where to comment). A fuel-mix value is none of these, and a filing that restates a target does not enact it.Definition ↗

eligible renewable resources or renewable energy credits, or a combination, equal to at least 15 percent of load each year from 2020enacted Washington State Legislature · RCW 19.285.040 Energy conservation and renewable energy targets · (2)(a)(iii)· of the qualifying utility's load As the document puts it"At least 15 percent of its load by January 1, 2020, and each year thereafter" (2)(a)(iii), after 3 percent (2012-2015) and 9 percent (2016-2019). Initiative 937, approved 2006-11-07 (2007 c 1). Subsection (2) also provides alternative compliance paths (accelerated conservation and demand response; the four percent incremental-cost cap), so a utility can comply below 15 percent, as Clark Public Utilities does.

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.
WA · 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 ↗

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).

Named on the sheet without a price, so in neither total: Residential Undergrounding Rates. Set in another document, not on the sheet, and unpriced, so in neither total: Automatic BPA cost adjustment (source ↗, SMC 21.49.081 Automatic BPA cost adjustment, printed where Ordinance 127473 Section 10 repeals it; PDF pp. 46-47). This sheet prices no adjustment, so there is no second total.
The statutory rule applies: excess kilowatt-hours carry forward as a credit and any balance is granted to the utility each year. Export is not permitted in the utility's network areas, most of downtown Seattle and parts of First Hill, South Lake Union and the University District, so net metering is unavailable there
A municipal utility publishes no numbered net-metering schedule; the terms come from the statute and the utility's own service pages, and no effective date is stated.Source ↗read 2026-09-18

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.
BPA supply accounts (pipeline/config/crosswalks/bpa_customer.csv and supply_accounts.csv)
Bonneville Power Administration (RHWM outputs, Provider of Choice CHWM calculation, CDQs, customer products lists, product change letter), Snohomish County PUD (2025 Annual Report; Electric Utility Rates, Schedule 7; electric rates page) and Seattle City Light (financial statements for 2016, 2018, 2022, 2024 and 2025; 2021A and 2026A official statements; residential rates page) with the City of Seattle's rate ordinances, cited per row; FERC coverage lines cite PUDL's FERC Form 1 and EQR extracts (CC-BY-4.0), the eCFR and FERC's CID listing
Entitlements (MWa), demand quantities (kW), forecasts net of resources (MWa), dollars (USD), energy received (MWh, or MWa as an average) and a disclosure attribution (MWh), each with its own period and document, never added, subtracted or divided across one another. A figure names the BPA product in force during its period; a price per MWh appears only where the utility publishes the same period's BPA energy in MWh in the same document, badged derived. A note's Block and Slice rows are components of the year's purchase, never products, never added to its total and never priced. The bill trace quotes the utility's residential sheet and prints a price only where the utility does, in its unit; the share of a bill that pays for BPA power is shown only where a document states it.
Display names and aliases (pipeline/config/crosswalks/aliases.csv)
Display names verified against each organization's own website; EIA legal names retained as aliases
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.
