- claim
- EPA distinguishes annual-volume electricity matching from hourly matching that normally considers the same region as consumption.
- attribution
- U.S. Environmental Protection Agency, 24/7 Hourly Matching of Electricity; independently worded account of its explanatory definitions.
- claim date
- Original publication date not established. The page states last updated 12 December 2025; that update is not treated as a new procurement event.
- scope
- What annual-volume matching alone establishes compared with hourly and regional matching. This is not an emissions audit or assessment of any named PPA, grid or project.

source notice: Source copyright and any applicable third-party rights are retained. Minimal independently worded attributed facts and ordinary unframed links only. No copied passages, figures, tables, model inputs, images, databases or broad source-use grant; no endorsement. No open licence is asserted unless separately identified for the exact component.
- EPA: annual-volume and hourly/regional definitions (Method and source context)
- supporting evidence
No supporting-evidence recorded.
- counter evidence
No counter-evidence recorded.
- method differences
- Annual volume, hourly timing, procurement location, actual grid supply, location-based carbon intensity and congestion each need their own evidence.
- finding
- supported within stated bounds
- reason
- The inspected definitions support this distinction. They do not establish a named buyer’s hourly matching, local carbon intensity, actual power delivery or congestion outcome.
- unresolved questions
- A named case still needs load and generation timestamps, certificate/contract boundaries, geography and relevant grid evidence. No congestion, additionality or zero-emissions outcome is inferred.

Dossier publication record
This is ComputeFinder's editorial record. Its checked on date retains the scoped claim-evidence check; adding this representation does not perform a new source or editorial check. Unknown publication dates and dossier-specific interests remain unrecorded, separately from the cited sources.

- publication date
- Not recorded
- data period
- Selected procurement definitions; no measured hourly electricity, emissions or transmission-congestion period is admitted.
- scope
- What annual-volume matching alone establishes compared with hourly and regional matching. This is not an emissions audit or assessment of any named PPA, grid or project.
- method
- Bounded editorial review of the recorded original, supporting and counter-evidence citations, with separate measurement definitions, a scoped finding and unresolved questions. This is not a systematic evidence review or an empirical site study.
- evidence type
- editorial_review
- assumptions
- Annual volume, hourly timing, location, physical grid supply and grid effects require separate evidence.
- uncertainty
- The source is an explanatory EPA page, not measured hourly data. Its displayed update date is 12 December 2025; market conditions are not freshly generalised. The dossier’s editorial publication date and dossier-specific funding/interests declaration are not recorded. Null interests do not mean that none exist. checked_on repeats the retained scoped claim-evidence check; it is not a new editorial metadata or source check.

- reuse terms
- CC BY 4.0 applies only to ComputeFinder-owned original dossier wording and compilation rights. Cited third-party sources retain their own exact notices, attribution, reuse terms and exclusions; no source licence or endorsement is inherited.

- related question
- What does annual renewable-electricity matching establish about hourly local power and grid effects?
- cannot establish
- A named case still needs load and generation timestamps, certificate/contract boundaries, geography and relevant grid evidence. No congestion, additionality or zero-emissions outcome is inferred.
