Guodian Zhongshan Minzhong Natural Gas Power Cogeneration Project

Audit Analysis

A CDM natural-gas cogeneration project with VVB-confirmed additionality (combined test) and a well-understood energy-efficiency design, but significant gaps in monitoring data, an outdated 2011 grid emission factor, a project-specific baseline, and a 10× discrepancy in claimed ERR between the validation report and an appendix. The absence of any verified monitoring results or leakage percentage weakens confidence in the actual credit delivery.

Project Description

Red Flags

• ⚠10× discrepancy in total ERR: validation report states 927,549 tCO₂e while an appendix lists 9,275,490 tCO₂e — a decimal-place error that undermines data reliability
• ⚠No monitoring period, verified ERR, or usage monitoring method found in any extracted document despite a 10-year crediting period (2014–2023)
• ⚠Grid emission factor frozen at the 2011 national average (0.6323 tCO₂/MWh) with no evidence of periodic update across the 2014–2023 crediting window
• ⚠12 Corrective Action Requests raised and closed during validation, including a coal baseline EF correction (94.6 → 87.3 tCO₂/TJ) and an IRR spreadsheet error, indicating initial PDD quality issues
