El Gallo Hydroelectric Project.

Audit Analysis

The El Gallo Hydroelectric Project is a straightforward CDM hydro project displacing grid electricity in Mexico, with a sound jurisdictional baseline and a valid barrier-test additionality assessment. However, the validation report identified 14 material findings (all subsequently corrected), the extraction confidence is low, and several key monitoring and transparency fields are absent from the available record. The ERR figure discrepancy between the PDD and validation report is likely an annual-versus-lifetime confusion but remains a documentation clarity concern.

Project Description

Red Flags

• ⚠14 material findings were identified during validation (mismatched participant lists, incorrect data sources, missing boundary description, wrong units), all corrected but indicating weak initial PDD quality
• ⚠ERR figure contradiction: PDD states 406,818 tCO₂e while the validation report states 58,117 tCO₂e — a 7× gap that, while likely annual vs. lifetime, was not explicitly reconciled in the documents
• ⚠Minimum extraction confidence is rated low, meaning at least one key document was poorly readable and the full evidentiary picture may be incomplete
• ⚠No monitoring report is present in the evidence set, so actual delivery against the claimed rate cannot be independently verified
