Umut-I Hydropower Plant, Turkey

Audit Analysis

The Umut-I Hydropower Plant is a registered VCS renewable energy project with confirmed additionality and a jurisdictional grid-emission-factor baseline, but it is undermined by an extensive list of material findings (over 40), more than 50 corrective actions, a 40% under-delivery against ex-ante estimates, and a significant discrepancy between the verified ERR (23,347 tCO₂e) and the ex-ante lifetime estimate (76,733 tCO₂e). The project type carries inherently low permanence and leakage risk, yet the documentation quality and internal consistency across reports are poor, and the low extraction confidence further erodes trust in the extracted data.

Project Description

Red Flags

• ⚠Actual emission reductions were 40% lower than ex-ante estimates due to seasonal variations, as noted in the verification report material findings
• ⚠Verified ERR of 23,347 tCO₂e (verification report, Feb 2025) differs by a factor of ~3.3 from the 76,733 tCO₂e figure in the validation report (Dec 2024), with no clear reconciliation in the extracted record
• ⚠Shared metering across Umut-I, II, and III plants with proportional allocation introduces measurement uncertainty that is not fully documented with calibration records
• ⚠Over 50 corrective actions were required by the VVB, including missing baseline validity assessment per VCS Standard v4.7 para 3.9.8, incorrect baseline emission formula, and inconsistent net electricity production values (61,595 MWh vs 17,145 MWh)
• ⚠CORSIA eligibility and CCP status are not stated in any available document, leaving dual-channel risk unassessed
