Audit Analysis

The Ha Tay Hydropower Project is a small-scale CDM hydro project with a confirmed investment-test additionality assessment by TÜV NORD CERT, but its documentation record is marred by six material findings (including PDD calculation errors and an equipment-count correction) and four cross-document contradictions. The project's straightforward avoidance-based design carries low reversal risk, yet the absence of verified ERR figures, safeguards detail, and a consistent baseline characterization limits confidence in the claimed reductions.

Red Flags

  • Six material findings in the verification record, including calculation mistakes in the PDD's total output and emission tables and an incorrect turbine/generator count (3 vs 2 units), indicating the foundational project design document contained errors that required correction.
  • Two monitoring reports from the same year (April 2020 and October 2020) report materially different total ERR figures (18,932 vs 14,826 tCO₂e), a 28% discrepancy that is not explained in the extracted record.
  • Baseline method is characterised as 'project-specific' in the 2020 monitoring report but 'jurisdictional' in the 2016 PDD, creating ambiguity about whether the grid-emission-factor baseline is truly standardised or project-tailored.
