Wind Power Project At Anthiyur, Tamil Nadu
Score Breakdown
Integrity
verified The validation/verification record indicates additionality was assessed using an investment test and confirmed by the VVB.
missing Leakage treatment is inconsistent and the latest monitoring report does not address leakage or provide a quantified deduction.
Transparency
verified Key MRV elements are present (named VVB, defined monitoring period, and ERs reported for 2023).
missing Numerous corrective actions and cross-document inconsistencies reduce confidence in the clarity and reliability of reported data.
Claim Safety
verified The project is explicitly not CORSIA-eligible, reducing certain double-claiming/eligibility risks.
missing Over-crediting risk is elevated by contradictions in ER figures and by MR corrections requested for ER calculations and monitoring parameters.
Documentation
verified A relatively large document set was available (34 documents including PDD, monitoring, validation, and issuance) with high extraction confidence.
missing The monitoring report lists multiple CARs/corrective actions, indicating documentation and internal consistency weaknesses at verification.
Detailed Analysis
Integrity
Additionality appears reasonably supported: the validation/verification record indicates an investment test and that the VVB confirmed additionality. Baseline setting is project-specific (not a standardized/jurisdictional baseline) and the extracted record does not show when the baseline was last reassessed, which weakens robustness. Leakage is a key gap: the latest monitoring report does not address leakage and no leakage deduction is quantified, despite earlier documentation treating leakage differently.
Transparency
The monitoring report (2024-05-28) clearly states the monitoring period (2023-01-01 to 2023-12-31), names the VVB (VKU Certification Pvt. Ltd.), and reports ERs with claimed and verified totals aligned in the extracted record. Transparency is undermined by the long list of corrective actions in the monitoring report, including inconsistencies between the monitoring report and ER sheet, meter replacement details, and missing/updated calibration certificates. These issues suggest that while information is present, it required substantial correction and reconciliation.
Claim Safety
The project is marked as not CORSIA-eligible, which lowers the risk of certain aviation-related claims. However, claim safety is weakened by over-crediting risk signals: the monitoring report requests corrections to ER values and inconsistencies between reported parameters and the ER sheet, and there are contradictions in ER totals across validation/monitoring documents. Leakage treatment inconsistency (negligible vs not addressed) further increases the risk that stakeholders could overstate the rigor of emissions accounting.
Documentation
Documentation coverage is relatively strong: the extracted record references a PDD, monitoring report, validation report, and issuance records, with 34 documents used and high extraction confidence. Nevertheless, the monitoring report (2024-05-28) includes multiple corrective actions/CARs (including CAR B1–B4 and CAR C1) focused on metering changes, calibration evidence, and calculation consistency, indicating that document quality and internal coherence were not clean on first submission. The presence of an 'unknown' document type in the evidence list also suggests some cataloging/traceability gaps.
Overall
Overall quality is moderate due to solid basic structure (VCS wind methodology AMS I.D., VVB involvement, and a defined 2023 monitoring period) but weakened by repeated cross-document contradictions and MRV correction needs. For ER totals, the 28,782 figure is privileged because it appears in the more recent monitoring/validation records and matches claimed vs verified in the extracted record, while the 10,485 figure comes from an older validation report version; the discrepancy still materially reduces confidence. For leakage, the latest monitoring report stating leakage is not addressed is privileged over the older validation report’s 'deemed negligible' statement because it is more recent and should reflect current accounting; this inconsistency lowers integrity and claim safety. For safeguards/grievance/FPIC, the 2024 monitoring report is privileged over the 2010 monitoring report due to recency, but the reversal over time indicates reporting inconsistency. For the crediting period, the 2016–2026 period from the 2024 monitoring report is privileged over the 2006–2016 period in the 2017 monitoring report due to recency, but the contradiction is significant and suggests record-control issues, lowering transparency and documentation scores.
Audit Analysis
This is a grid-connected wind power project under AMS I.D. with investment additionality confirmed by the VVB and matching claimed vs verified ERs in the latest monitoring record. However, multiple internal inconsistencies across documents (including ER totals, leakage treatment, and even the stated crediting period) and numerous corrective actions related to metering/calibration and calculation consistency increase over-crediting and reliability risk.
Project Description
This project is a 14.85 MW wind farm with 9 Vestas (India) Pvt. Ltd. WTGs, generating renewable electricity. It is approved by the VCS Board as a CDM1GHG program and falls under sectoral scope: Energy Industries. The project follows Version 14 of AMS-1.D.
Red Flags
- Conflicting ER totals across validation/monitoring documents (10,485 vs 28,782) indicate data reliability issues.
- Leakage is not addressed in the latest monitoring report despite earlier documents deeming it negligible, creating methodological inconsistency.
- Many corrective actions/CARs relate to meter replacement, calibration certificates, and inconsistent parameters/ER calculations, elevating MRV risk.
- Crediting period is inconsistent across monitoring reports (2006–2016 vs 2016–2026), raising questions about period eligibility and record accuracy.

Cosa migliorerebbe questo punteggio
- Publish a clear reconciliation note across versions explaining the ER total changes (10,485 vs 28,782) and provide a single authoritative ER table tied to the final ER sheet and verification conclusion.
- Standardize leakage treatment in the monitoring report (explicitly state negligible leakage with justification under AMS I.D. or apply a quantified deduction) and ensure consistent crediting period statements across all project documents.
Questi suggerimenti indicano quali prove pubbliche aggiuntive potrebbero migliorare il livello di confidenza di questa valutazione. Non garantiscono un punteggio futuro più alto.
