Audit Analysis
The Sidlaghatta Biogas Project has a VVB-confirmed additionality assessment and a quantified 10% leakage deduction, but is undermined by severe operational underperformance (only 671 of 1,716 units functioning), five corrective action requests, nine cross-document contradictions, and the absence of a buffer pool or reversal-risk treatment. The project delivered roughly 40% of its pro-rata ex-ante expectation for the final monitoring period, reflecting a baseline that was overly optimistic relative to actual unit survival rates.
Red Flags
- Only 671 of 1,716 installed biogas units were functioning during the 2019–2020 monitoring period (39% operational rate), yet the ex-ante baseline assumed near-full operation
- Five corrective action requests (CAR 01–05) were raised by the VVB, indicating unresolved verification deficiencies
- No buffer pool percentage is stated in any available document, and reversal events are explicitly 'not addressed'
- 23 non-functioning units were not accounted for in the emission reduction calculations of the previous monitoring report (MP5)
- Nine contradictions across documents, including a 100× discrepancy in the FNRB value (78 vs 0.78) and conflicting crediting-period start dates
