Cam Lam VN Solar Power Plant

Audit Analysis

The Cam Lam VN Solar Power Plant is a CDM-registered solar project with a jurisdictional baseline and VVB-confirmed additionality, but its credibility is undermined by 15 material findings spanning multiple PDD revisions (GPS errors, missing evidence, equipment mismatches) and a significant discrepancy between the PDD's ex-ante estimate (66,991 tCO₂e) and the monitoring report's verified figure (95,952 tCO₂e) for the 2021–2022 period. The project type (utility-scale solar) inherently carries low reversal and leakage risk, and the smart-meter monitoring approach is sound, but the ERR gap and the age of the grid emission factor (2017) warrant caution before relying on the claimed reductions.

Project Description

Red Flags

• ⚠Monitoring report (2022) reports 95,952 tCO₂e for the 2021–2022 period while the PDD (2021) ex-ante estimate is 66,991 tCO₂e for the full 7-year crediting period — the verified figure is roughly 5× the pro-rata expectation for the elapsed period, raising over-crediting concerns
• ⚠15 material findings in the verification/monitoring record, including incorrect GPS coordinates, missing evidence for generation estimation and grid emission factor in PDD v1.0, and inconsistent module capacity data, all requiring PDD corrections through v3.3
• ⚠Grid emission factor of 0.8492 tCO₂/MWh is from 2017, applied to 2021–2022 monitoring — a 4–5 year gap that may not reflect Vietnam's evolving grid mix
• ⚠CORSIA eligibility and CCP status are not stated in any available document, leaving dual-channel risk unassessed
