Audit Analysis

The Ho Nui Coc Hydropower Project has a solid additionality foundation (VVB-confirmed investment test) and a jurisdictional baseline, but the validation report identified three material findings including a non-conservative grid emission factor and non-compliant monitoring parameters, all requiring corrective action. Multiple key transparency and monitoring fields are absent from the extracted record, and the low extraction confidence further limits assurance. The project is a straightforward small-hydro displacement project with reasonable leakage treatment, but the quality issues flagged at validation and the sparse documentation lower overall confidence.

Red Flags

  • Validation report identified a non-conservative grid emission factor (0.59512 used vs. 0.5764 official), meaning the project initially over-claimed credits relative to the official baseline
  • Three material findings and five corrective actions were required at validation, indicating significant quality issues in the original submission
  • Monitoring parameters did not initially comply with ACM0002 requirements for hydroelectric plants
  • Low extraction confidence across the document set limits the reliability of the extracted data
