DakRTih Hydropower Project, Vietnam

Audit Analysis

The DakRTih Hydropower Project has a VVB-confirmed additionality assessment and a reputable verification body, but is undermined by six material findings requiring corrective action, a seven-fold discrepancy between the ex-ante and monitoring-period ERR figures, contradictory baseline and leakage treatments across documents, and the absence of any verified ERR figure. The project's compliance posture is weak, and the over-crediting risk is significant.

Project Description

Red Flags

• ⚠Six material findings (CARs) in the monitoring report, including incorrect methodology version (v11 vs v19), missing surface water permit, non-compliance with EB 66 Annex 47, and an outdated grid emission factor
• ⚠The monitoring report claims 1,371,906 tCO₂e for a 2.33-year period versus an ex-ante estimate of 555,166 tCO₂e for the full 7-year crediting period — a pro-rata over-delivery of roughly 740%, which is extreme even for a flow-variable hydro project
• ⚠Leakage deduction is 0% with contradictory justifications: the validation report (2019) deems it negligible, while the monitoring report (2022) states it was not addressed
• ⚠Baseline method is described as 'project-specific' in the monitoring report but 'jurisdictional' in the PDD, creating ambiguity about the reference case
• ⚠No verified ERR figure is available in the extracted record; only the claimed figure from the monitoring report is present
