Score Breakdown

Integrity

verified Additionality was confirmed by the VVB, and the project uses an investment test under ACM0002.

missing Leakage is not addressed in the issuance record, and the record shows no buffer pool percentage or reversal treatment.

Transparency

verified The monitoring period is stated as 2020-10-01 to 2021-12-31, and the VVB is named as EPIC Sustainability Services Pvt. Ltd.

missing The record shows a major discrepancy in verified emission reductions and multiple monitoring-report inconsistencies, reducing confidence in public reporting.

Claim Safety

verified The project is an avoidance project in the renewable energy sector with a grid emission factor reported for 2021.

missing The verified emissions reduction figure is heavily contradicted across documents, and leakage treatment is inconsistent.

Documentation

verified A substantial number of documents were used, and the record includes a named VVB plus a recent issuance date in 2023.

missing Extraction confidence is low, and the monitoring report required many corrective actions, including missing parameter details and internal inconsistencies.

Detailed Analysis

Integrity

The project has a positive additionality signal because the VVB confirmed an investment test, and the baseline was reassessed in 2021. However, integrity is weakened by the lack of a buffer pool figure, reversal treatment not being addressed, and leakage justification being marked as not addressed in the issuance record. The monitoring report also lists many corrective actions, which suggests unresolved implementation and data-quality issues.

Transparency

Transparency is limited by inconsistent reporting and incomplete monitoring detail. The monitoring period is stated, and the VVB is identified, but usage monitoring method is not found in the extracted record and the report includes multiple inconsistencies about the monitoring period, self-consumption calculation, and parameter tables. The low extraction confidence further reduces trust in documentation quality.

Claim Safety

Claim safety is materially weakened by the contradiction in verified emission reductions: one record supports 309,207 tCO2e while another supports 2,854,350 tCO2e. I privileged the issuance record’s 309,207 tCO2e because it is the more recent document and appears to be the final issuance source, but the size of the discrepancy still raises over-crediting risk. Leakage treatment is also inconsistent across documents, which adds to the risk that the credited reductions are overstated.

Documentation

Documentation quality is below average because the extraction confidence is low and the evidence set contains many corrective actions from the verification process. The project does have a named VVB and a large number of source documents, but key fields such as leakage deduction, buffer pool, usage monitoring method, and several operational details are missing or not stated. The crediting period also appears contradictory across documents, which further weakens confidence in the record set.

Overall

I privileged the issuance record for the verified emissions figure and crediting-period end state because it is the most recent and operationally authoritative document, but the older monitoring/validation figures remain a serious contradiction that cannot be ignored. I also privileged the later documents for safeguards and benefit-sharing because they are more recent and specific, yet the earlier documents show the opposite, so reliability is still reduced. Overall, the project looks plausible but not robustly documented, with material uncertainty around emissions accounting, leakage, and report consistency.

Audit Analysis

The project has some positive integrity signals, including VVB-confirmed additionality and a recent baseline reassessment, but key risk areas are weakly documented. Reliability is reduced by low extraction confidence, multiple corrective actions, and major contradictions in reported emissions reductions, crediting period, and leakage treatment.

Project Description

The Alkumru Hydroelectric Power Plant is located in Eastern Anatolia, Turkey and utilizes the energy of the Botan River to produce electricity. With a maximum water level of 647m and a tail water level of 541.80m, the project is estimated to produce 881,210 MWh of electricity annually, which equates to 475,143 tonnes of VCUs per year.

Red Flags

  • Large contradiction in verified emission reductions: one document set supports 309,207 tCO2e while another supports 2,854,350 tCO2e, indicating a serious reliability issue.
  • Leakage treatment is inconsistent: one source says leakage was deemed negligible, while the issuance record says leakage is not addressed.
  • The monitoring report contains numerous corrective actions and inconsistencies, including unclear self-consumption calculation, missing calibration details, and inconsistent monitoring-period statements.

Cosa migliorerebbe questo punteggio

  • Publish a reconciled emissions-reduction statement that explains the 309,207 versus 2,854,350 tCO2e discrepancy and identifies the final authoritative value.
  • Provide a complete monitoring annex with leakage treatment, buffer or reversal provisions, usage-monitoring method, and closure of all corrective actions.

Questi suggerimenti indicano quali prove pubbliche aggiuntive potrebbero migliorare il livello di confidenza di questa valutazione. Non garantiscono un punteggio futuro più alto.
