CBAM Electricity: documentary evidence and verification readiness

Electricity has a distinct CBAM evidence structure. The record may need to connect the imported electricity quantity to the generation source, relevant technical and contractual links, reporting period, grid or generation data and the criteria applicable to any use of actual emissions instead of default methodology.

Typical breaks include an imported quantity that cannot be reconciled with the supporting energy record, generation data from a different period, an asserted technical link without the corresponding documentation, or use of an actual-emissions value without evidence that the applicable criteria are met. Grid data and contractual records can also refer to different boundaries.

Where generation information is relied on, the operator may need to support the generation installation, production and export quantities, relevant fuel or generation data, reporting period and the records behind the emissions value. The documentary package should make clear whether the position relies on default methodology or on the conditions for actual values.

The importer should be able to connect the imported electricity and period to the relevant generation information and the methodology used in the CBAM position. Where actual values are used, the file must keep the documents supporting the technical and methodological conditions rather than relying on a generic statement about the electricity source.

Electricity evidence is highly time-sensitive. Generation mix, grid information, contracts and technical links can change across periods. The reviewed record should identify the period used, the source of the data, the methodology applied and any correction that changed the quantity or emissions position.

For verification readiness, the electricity dossier should make quantity, generation source, period, applicable methodology, supporting technical criteria and source records traceable. Weetra can review that documentary coherence but does not determine whether the statutory verification requirements are satisfied.

Weetra follows the electricity position from imported quantity and period back to the generation or grid evidence, the methodology used and the source records supporting any actual-emissions figure. The review distinguishes what the record establishes from assumptions that are not documented.

For electricity, later review depends on keeping the imported quantity, period, generation or grid evidence, methodology and any technical-link documents used to support the reported figure.

Weetra’s public Case Library does not currently include a dedicated electricity import case. The page therefore links to the broader library and uses only general documentary-review examples rather than inventing a sector case.
