Hebei Weichang Yangshugou Wind Power Project

Audit Analysis

A CDM wind project in China using the standard ACM0002 methodology with a VVB-confirmed combined additionality test and a grid-based baseline. The project delivered roughly one-third of its pro-rata annual expectation in the 2012 monitoring period, indicating conservative crediting. Several contradictions between the validation and monitoring reports (baseline method, leakage justification, crediting period dates) reduce confidence in data consistency, though most are explainable by differing document scopes.

Project Description

Red Flags

• ⚠Contradiction in baseline method: the validation report (2011) describes a jurisdictional baseline while the monitoring report (2013) labels it 'project' — the grid emission factor of 0.9502 (2009) supports the jurisdictional reading, but the inconsistency undermines baseline clarity.
• ⚠Leakage justification is contradictory: the validation report states leakage was 'deemed negligible' while the monitoring report calls it 'quantified,' yet the deduction is 0% in both cases — the nature of the assessment is unclear.
• ⚠The 2012 monitoring period delivered only ~34% of the pro-rata annual expectation (36,621 vs ~108,181 tCO₂e), raising questions about the accuracy of the original ex-ante estimate or actual wind resource performance.
• ⚠No buffer pool percentage is stated in any available document, leaving permanence risk unquantified despite the absence of reversal events.
