Each year as Commerce's fuel-mix system holds it: MWh and shares of the utility's Washington retail sales including line losses, never generation and never a compliance finding. Years before CY2018 are Commerce's restatement under the 2019 method, not the disclosure published for the year; no change is taken across that break.

| Before CY2018: restatedCommerce's current system run over what utilities reported for a year before CY2018. The disclosure published for that year followed the old law, which required Commerce to assign fuel shares to unspecified power; this run keeps unspecified power as its own Market category, and Commerce's statewide totals for these years differ from the statutory reports.

Categories and shares as Commerce computed them from declared resources, the BPA system mix (BPA's own mix applied to BPA deliveries, remainder unspecified) and unspecified purchases; a declared resource needs ownership or an auditable contract and its REC; renewable power without the REC counts as unspecified. Not an emissions accounting.
Not a CETA-obligated electric utility in Ecology's allowance schedule (or not linked by the reviewed crosswalk); only Washington retail utilities subject to the Clean Energy Transformation Act receive no-cost allowances. Checked wa-ecology-cca-allowances 2026-09-18

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.
No EIA-861 rows in the atlas 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.
