Hebei Weichang Zhangjiawan Wind Power Project

Audit Analysis

A CDM wind power project in China verified by Bureau Veritas with a combined additionality test, but the verification surfaced a below-benchmark IRR (6.63% vs 8%), meter accuracy deficiencies, and 18 corrective actions. The project is an avoidance-type (grid displacement) with no reversal risk, and the first monitoring period delivered roughly 72% of the pro-rata expectation, which is conservative. Multiple contradictions between the PDD, validation report, and monitoring report reduce confidence in the consistency of the project record.

Project Description

Red Flags

• ⚠IRR of 6.63% falls below the 8% benchmark cited in the validation report, raising questions about the robustness of the additionality claim despite VVB sign-off
• ⚠Meter accuracy for the backup line (1.0) and 35 kV lines (0.5S) is lower than the 0.5 and 0.2S specified in the registered PDD, requiring a 1.005 correction factor and a meter replacement
• ⚠Five contradictions across documents (leakage justification, additionality test type, baseline method, ERR figures, crediting period) indicate inconsistent project documentation
• ⚠18 corrective actions were required at validation, including IRR calculation inconsistencies, missing stakeholder engagement details, and PDD-IRR spreadsheet discrepancies
