Hami Tianrun Shisanjianfang I 49.5MW Wind Power Project

Audit Analysis

A 49.5 MW onshore wind project in China registered under CDM (ACM0002) with VVB-confirmed additionality and a jurisdictional grid-emission-factor baseline. However, the project carries three corrective action requests from validation, inconsistent leakage justifications across monitoring reports, and a significant discrepancy between the ex-ante ERR estimate (92,288 tCO₂e) and the monitoring-period claim (212,082 tCO₂e) that raises over-crediting concerns. Verified ERR figures are not available in the extracted record, limiting the ability to confirm actual delivery.

Project Description

Red Flags

• ⚠ERR contradiction: the validation report (2012) states an ex-ante estimate of 92,288 tCO₂e for the full 7-year crediting period, while the 2020 monitoring report claims 212,082 tCO₂e for the 2.83-year monitoring period (2017–2019). On a pro-rata basis the monitoring claim is roughly 5.7× the expected share, and the implied capacity factor exceeds 100%, which is physically impossible for a 49.5 MW turbine. This strongly suggests a unit error, a mislabelled period, or an over-crediting risk.
• ⚠Three corrective action requests from the validation stage (LoAs not obtained, additionality tool v6.0 compliance, non-conservative combined-margin calculation) are listed as required, but no document in the extracted record confirms they were closed before registration.
• ⚠Leakage justification is inconsistent: the 2017 monitoring report states leakage was 'deemed negligible' while the 2020 monitoring report records it as 'not addressed', with a 0% deduction in both cases.
• ⚠Baseline method is described as 'jurisdictional' in the validation report but 'project' in the 2020 monitoring report, creating ambiguity about which baseline was actually applied.
