Şenbük WPP Project

Audit Analysis

The Şenbük WPP is a Gold Standard wind project with a reputable VVB (Bureau Veritas) and recent monitoring, but it is undermined by a 4.6× over-delivery relative to the pro-rata ex-ante expectation, a turbine-count discrepancy (10 vs 20) flagged in the PDD, and numerous unresolved corrective actions. Multiple contradictions across documents—additionality status, baseline method, leakage justification, and grid emission factor—erode confidence in the data chain. The project is functional but carries meaningful over-crediting and documentation risk.

Project Description

Red Flags

• ⚠Verified ER of 210,715 tCO₂e for a 9-month monitoring period is approximately 4.6× the pro-rata expectation of ~46,000 tCO₂e derived from the 429,176 tCO₂e lifetime ex-ante estimate over a 7-year crediting period, raising a serious over-crediting concern.
• ⚠The PDD contains a turbine-count discrepancy (10 vs 20 turbines) flagged as a corrective action, suggesting the ex-ante estimate may have been calculated for a different project configuration than what is actually operating.
• ⚠The validation report (Dec 2024) recorded additionality as not verified, while the subsequent verification report (Aug 2025) recorded it as verified—an unexplained reversal that weakens the additionality evidence chain.
• ⚠Approximately 40 corrective actions remain outstanding in the verification report, including missing sustainability monitoring parameters, incorrect crediting-period dates, and unresolved meter calibration details.
• ⚠Free, Prior and Informed Consent (FPIC) was not conducted, despite the project being located in a rural area with local communities.
