The Cevizlik Run-Of-River Hydroelectric Power Plant

Audit Analysis

The Cevizlik run-of-river hydro project is a well-structured VCS avoidance credit with VVB-confirmed additionality and a jurisdictional grid-emission-factor baseline, but it is held back by a low extraction confidence across its 31 source documents, a moderate under-delivery of roughly 83% of the pro-rata ex-ante expectation, and a cluster of 13–18 corrective action requests that point to documentation-quality gaps. No reversal events or material integrity failures were found, and the 0% leakage deduction is defensible for a grid-displacement hydro plant.

Project Description

Red Flags

• ⚠Min extraction confidence rated 'low' across the 31-document evidence base, meaning at least one key document was poorly readable and some facts may be incomplete or misread.
• ⚠Regulatory surplus requirement was not demonstrated in the additionality assessment (flagged as a CAR in the verification report).
• ⚠Grid emission factor is anchored to 2008 data (0.492925 tCO2/MWh); although the baseline was reassessed in 2022, the underlying year is more than 15 years old.
• ⚠Project delivered only ~83% of the pro-rata ex-ante expectation for the elapsed monitoring period, attributed to precipitation variability.
