Yahyali Wind Power Plant

Audit Analysis

The Yahyali Wind Power Plant is a Gold Standard wind project with VVB-confirmed additionality and a conservative credit outcome (verified ERR exceeds both the claimed figure and the pro-rata ex-ante expectation). However, eight contradictions across documents — including a 17% discrepancy in the grid emission factor and a near-doubling of ERR values between verification reports issued one day apart — combined with approximately 40 corrective actions and low extraction confidence, significantly undermine confidence in the underlying data quality.

Project Description

Red Flags

• ⚠Grid emission factor differs by 17% between two verification reports issued on consecutive days (0.6488 on 2025-01-21 vs 0.553 on 2025-01-20), directly affecting the credit calculation
• ⚠Total ERR claimed and verified figures differ by roughly a factor of two between verification reports one day apart (136,881 vs 67,669 claimed; 148,014 vs 79,826 verified), indicating unresolved data reconciliation issues
• ⚠Approximately 40 corrective actions were required by the VVB, spanning missing EPIAS records, calibration certificates, incorrect turbine names, wrong installed capacities, and missing boundary coordinates
• ⚠Baseline method is described as 'project' in the 2025 verification report but 'jurisdictional' in the 2022 PDD, creating ambiguity about the baseline construction
• ⚠Free, Prior and Informed Consent (FPIC) was not conducted, despite the project's proximity to Karaköy Village
