The Uruguay team can place operations, finance, and data owners in charge of charging electricity source. After the supplier provides the source ledger, calculation sheet, method note, and approval record, the dealer should recalculate the share of each electricity source from charging-pile meter readings, and check the validity of the supplier's evidence. Link charging electricity source to reporting period, boundary, source, and calculation version in the acceptance sheet rather than using only a model or project name. When charging electricity source share is used in external promotion in Uruguay, its method and evidence must meet local competent-authority requirements and be recognised by the licensed institution, with applicable contractual terms also applying. Before closing charging electricity source, review the corresponding import checklist. Electricity data whose source cannot be verified must not be used in external promotion; after an electricity method change, recalculate and retain the prior version. When closing charging electricity source, the reviewer should state which sustainability records task the evidence supports.
