Audit Analysis
A VCS-registered wind energy avoidance project in Tamil Nadu with a VVB-confirmed investment additionality test, but plagued by significant verification issues including a 33% under-delivery versus ex-ante estimates, calibration gaps, unaddressed leakage, and multiple contradictions between the 2021 and 2024 verification reports. The project is conservative in its actual delivery (72% of pro-rata expectation), which mitigates over-crediting risk, but the documentation and data-reliability gaps undermine confidence in the overall claim.
Red Flags
- The 2024 verification report shows verified ERs of 21,476 tCO2e versus 29,626 tCO2e in the 2021 verification report for what appears to be the same monitoring period (2016–2019), a 27% downward revision that is unexplained in the extracted record.
- Leakage deduction is 0% with the justification recorded as 'not addressed' in the 2024 verification report, while the 2024 monitoring report claims it was 'deemed negligible' — the verification report (higher authority) indicates the issue was never properly resolved.
- Five corrective actions remain open, including inability to verify annual ER values due to a missing ER sheet, missing project start-date evidence, and missing statutory clearances from the State Pollution Control Board.
- Calibration of the meter was not performed for the entire monitoring period; the latest calibration report (March 2016) is the only one on file, leaving 2017–2019 unverified for instrument accuracy.
