Hoa Tham Hydropower Project

Audit Analysis

The Hoa Tham Hydropower Project is a small-scale CDM hydropower project in Vietnam with a confirmed investment-test additionality and a jurisdictional grid baseline, but its quality is undermined by five material findings at validation (including IRR calculation errors and use of an outdated grid emission factor tool), a complete absence of monitoring-period data, and a significant discrepancy between the PDD and validation report on total emissions reductions. The project's avoidance-type design (displacing grid electricity) limits permanence risk, but the lack of a buffer pool and the unquantified 0% leakage deduction leave residual uncertainty.

Project Description

Red Flags

• ⚠Five material findings at validation, including incorrect application of tax incentives in the IRR calculation and use of an outdated grid emission factor tool (v1.1 instead of v2.2.1), indicating the initial additionality and baseline calculations contained errors that required corrective action.
• ⚠No monitoring-period data is available in the extracted record: no verified ERR, no monitoring period dates, and no usage monitoring method are stated, making it impossible to confirm actual delivery against the validated estimate.
• ⚠The PDD reports a total ERR of 77,749 tCO₂e while the validation report states 11,107 tCO₂e; although this is consistent with a total-over-crediting-period versus annual figure (77,749 ÷ 7 ≈ 11,107), the discrepancy was not explicitly reconciled in the documents.
