Audit Analysis
A CDM fossil-fuel-switch project (coal-to-gas, 119.8 MW) in Tamil Nadu, India, with a jurisdictional grid-emission-factor baseline and VVB-confirmed additionality. The project is fundamentally sound in design, but a significant grid-emission-factor discrepancy between the PDD and the monitoring report, 14 corrective action requests during verification, and the absence of a verified ERR figure in the extracted record create meaningful data-reliability concerns that temper confidence in the credit volume.
Red Flags
- Grid emission factor differs by orders of magnitude between the PDD (673.3 tCO₂/MWh) and the monitoring report (0.7339), creating uncertainty in the baseline credit calculation
- 14 Corrective Action Requests and 10 Clarification Requests were raised during verification, indicating material gaps in the registered monitoring plan (missing parameters EFCO2,f,y, COEFy, build margin, PEy, EFBL,upstream CH4)
- Verified ERR for the monitoring period (2010-12-16 to 2012-01-15) was not found in the extracted record, preventing independent confirmation of credit delivery
- PDD is dated 2012-11-27, which is unusually late for a project with a 2006 crediting-period start, raising questions about document provenance
