Aşağı Kaleköy Hydropower Plant

Audit Analysis

A small-scale hydropower avoidance project in Turkey using the well-established ACM0002 methodology, with VVB-confirmed additionality and a jurisdictional grid baseline. The project is under-delivering relative to its ex-ante expectation (approximately 66% of pro-rata), which is conservative, but significant data inconsistencies across documents and a discrepancy between the issuance figure and the monitoring report raise reliability concerns. Documentation quality is weakened by 12 corrective action requests, numerous data contradictions, and the absence of FPIC.

Project Description

Red Flags

• ⚠The issuance document records a claimed ERR of 3,626,218 tCO2e while the monitoring report (same date, 2026-04-16) reports only 2,400,394 tCO2e — a 51% discrepancy that suggests potential over-crediting at the registry level.
• ⚠The ex-ante lifetime ERR differs by 44% between the verification report (6,624,470) and the monitoring report (3,626,218), undermining confidence in the baseline calculation.
• ⚠12 corrective action requests and 12 clarification requests were raised during validation, and 21 corrective actions remain in the verification report, indicating persistent documentation and data-quality weaknesses.
• ⚠Free, Prior and Informed Consent (FPIC) was not conducted, despite the project involving a community-adjacent hydropower facility.
