Retail electricity sold
Full serviceA utility that sells electricity to customers. Full-service sales include both electricity and delivery.Definition ↗Short-form respondentA small utility that files Form EIA-861S instead of the full EIA-861: one total per state for sales, revenue and customers, full service only, with no customer classes. The atlas shows those totals as filed and derives no average price from them, because an all-class figure would not compare with class prices elsewhere.Definition ↗: state totals only.
WA · all customers, full service· BPAT
Filed on Form EIA-861S, the short form for smaller bundled-service utilities: sales, revenue and customers in total for each state and balancing authority, with no customer-class split. No average revenue per kWh is derived, because an all-class average is not comparable with the class figures on other utility pages. EIA's long-form adjustment rows for the state carry the same sales by class, so these totals are never added to a state, authority or class total.
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 ↗
checked 2026-09-18 Five kinds kept apart: what applies, what is owed, what the utility filed, what the issuing body decided, and the open proceeding. The disclosed-supply block above is the same utility's fuel mix as Commerce computed it; read it beside these rows, never as a verdict on them. Rows checked through 2026-09-18; a row past its review date is marked, not removed.

Files the EIA-861S short form, which has no reliability schedule. Source
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
Files Form EIA-861S, which asks whether programmes exist but no figures, so there is nothing to show and nothing is zero.
Demand response EIA-861 Schedule 6 Part B

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.
Geographic & reporting context
Clean-energy obligation assertions (pipeline/config/crosswalks/clean_energy_obligations.csv)
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.
