Ha Nang Hydropower Project

Audit Analysis

The Ha Nang Hydropower Project is a small-scale CDM hydropower project in Vietnam using the standardised AMS-I.D methodology, with additionality confirmed by KEMCO via an investment test. However, the project carries moderate concerns: the monitoring report over-claims emissions reductions by roughly 38% relative to the verified figure, leakage treatment is contradictory across documents, and six material findings (including baseline calculation errors and an expired methodology version) had to be corrected. The project is an avoidance-type hydropower scheme with no inherent reversal risk, but documentation gaps and the ERR discrepancy temper confidence.

Project Description

Red Flags

• ⚠Monitoring report claims 29,128 tCO2e for the period while the VVB verified only 21,028 tCO2e — a 38% over-claim that was not supported by the verification
• ⚠Leakage justification is contradictory: the validation report (Jan 2011) deems leakage negligible, but the monitoring report (Mar 2012) does not address leakage at all, leaving the 0% deduction without a consistent basis
• ⚠Baseline method is characterised as 'project' in the monitoring report but 'jurisdictional' in the validation report, creating ambiguity about whether the grid emission factor application is standardised or project-specific
• ⚠Six material findings (CARs/CLs) were raised during verification, including an incorrect baseline emission factor, an incomplete sensitivity analysis, and use of an expired methodology version
