Huadian Gansu Yumen Heiyazi Second Phase 48MW Wind Power Project

Audit Analysis

A 48 MW onshore wind project in Gansu, China, registered under CDM methodology ACM0002 with a combined additionality test confirmed by DNV. The project delivered approximately 79% of its expected first-year emissions reductions, indicating conservative crediting. Several contradictions between the validation and monitoring reports (baseline method, leakage justification, ERR figures, crediting period dates) introduce moderate uncertainty, but no material over-crediting risk is evident.

Project Description

Red Flags

• ⚠Contradiction in baseline method: the validation report (2011) describes a jurisdictional baseline while the monitoring report (2012) labels it 'project' — the methodology ACM0002 requires a grid-emission-factor (jurisdictional) baseline, so the monitoring report's characterisation is inconsistent.
• ⚠Total ERR figures differ between documents: 91,127 tCO2e in the validation report versus 71,990 tCO2e in the monitoring report. While the lower monitoring figure is conservative, the discrepancy is unexplained in the extracted record.
• ⚠Leakage justification is inconsistent: the validation report states leakage was 'deemed negligible' while the monitoring report says it was 'quantified,' yet the deduction is 0% in both cases.
• ⚠Crediting period dates differ between the validation report (2011-11-01 to 2018-10-31) and the monitoring report (2011-09-26 to 2018-09-25), creating ambiguity about the exact registration window.
