Chieng Cong Hydropower Project

Audit Analysis

The Chieng Cong Hydropower Project is a small-scale CDM hydro project in Vietnam with a VVB-confirmed investment additionality test and a reasonable 0% leakage deduction. However, the verification process surfaced 26 corrective action requests, equipment specifications that deviated from the PDD, and a contradiction in baseline methodology between the PDD and monitoring report. Several key verification parameters (FNRB, usage rate, CORSIA/CCP status) are absent from the extracted record, limiting full confidence in the credit's robustness.

Project Description

Red Flags

• ⚠26 Corrective Action Requests raised and closed during verification, indicating significant discrepancies between the PDD and actual project implementation
• ⚠Baseline methodology contradicts between the PDD (project-specific) and the monitoring report (jurisdictional), creating ambiguity about the baseline basis
• ⚠Generator capacity increased from 1,000 kW to 1,250 kW without apparent PDD amendment, and electricity meters were reduced from six to two by EVN decision
• ⚠FNRB value, usage rate, CORSIA eligibility, and CCP status are all absent from the extracted record, leaving key claim-safety parameters unverifiable
