Grid connected 156.1 MW Combined Cycle Power plant at Hazira, Gujarat

Audit Analysis

A CDM fossil-fuel-switch project (156.1 MW combined-cycle gas plant in Gujarat, India) with a VVB-confirmed investment additionality test and a jurisdictional grid-emission-factor baseline, but undermined by 20 material findings at validation, five cross-document contradictions (including a 54% grid-EF discrepancy and a baseline-method conflict), and a first monitoring period that delivered roughly 4.2× the pro-rata ex-ante expectation. The project's core methodology (AM0029) is well-established, yet the volume of unresolved documentation gaps and contradictions materially weakens confidence in the credit quantity and baseline integrity.

Project Description

Red Flags

• ⚠20 material findings at validation, including missing DNA approval, inadequate baseline scenario justifications (lignite, nuclear, grid import), and missing financing charges in the cost calculation
• ⚠Grid emission factor discrepancy: the PDD records 593.8 (likely kg CO₂/MWh) while the monitoring report uses 0.9163 t CO₂/MWh (≈916 kg CO₂/MWh), a 54% difference that directly inflates the credit quantity
• ⚠Baseline method contradiction: the validation report describes a 'project' baseline while the monitoring report states 'jurisdictional', creating ambiguity about which baseline was actually applied
• ⚠First monitoring period ERR of 385,292 t CO₂ is approximately 4.2× the pro-rata expectation of ~91,900 t CO₂ derived from the 765,718 t CO₂ lifetime ex-ante estimate, raising over-crediting concerns
• ⚠No buffer pool, no reversal-event tracking, and no quantified leakage percentage are recorded in the available documents
