Coke Dry Quenching (CDQ) Waste Heat Recovery for Power Generation Project of Wugang No. 9 and 10 Coke Ovens

Audit Analysis

A CDM waste-heat-recovery power generation project with VVB-confirmed additionality and no reversal events, but undermined by 18 material findings at validation, a grid emission factor discrepancy between the validation and monitoring reports, and several key transparency fields (verified ERR, FNRB, usage monitoring) left unstated. The project is structurally sound for its type but carries moderate documentation and data-reliability concerns.

Project Description

Red Flags

• ⚠18 material findings (CARs) at validation covering baseline, additionality, monitoring, and project boundary — indicating the initial PDD required substantial correction before registration
• ⚠Grid emission factor discrepancy: validation report (2009) used 0.89775 tCO₂/MWh while the monitoring report (2012) used 0.7718 tCO₂/MWh from the 2006 yearbook; the lower monitoring value is conservative but the inconsistency raises questions about which figure underpins the credit calculation
• ⚠Baseline method labelled 'project' in the validation report but 'jurisdictional' in the monitoring report — a labelling inconsistency that obscures whether the baseline is truly project-specific
• ⚠Crediting period differs between the PDD (2008-06-01 to 2018-05-31) and the monitoring report (2009-04-20 to 2019-04-19), creating ambiguity about the actual registered period
