30MW Puyo Hydropower Project

Audit Analysis

The 30 MW Puyo Hydropower Project is a standard CDM avoidance project with a jurisdictional grid baseline and VVB-confirmed additionality, but the available record is severely limited to a 2012 validation report and PDD with no monitoring data. A seven-fold discrepancy between the PDD and validation report on total emissions reductions, combined with 13 material findings at validation and low document extraction confidence, significantly undermines confidence in the project's data integrity and claim accuracy.

Project Description

Red Flags

• ⚠Total ERR discrepancy of 7× between the PDD (769,006 tCO₂e) and the validation report (109,858 tCO₂e) — the basis for the difference is unexplained in the available documents
• ⚠13 material findings (CARs) at validation covering missing methodology justification, inconsistent power-plant list, absent monitoring parameters, and incomplete additionality analysis
• ⚠No monitoring reports, verified ERR figures, or monitoring period data are present in the extracted record
• ⚠Low extraction confidence on at least one key document, reducing reliability of the available data
