Aslancik Hydro Power Plant Project
Score Breakdown
Integrity
verified The monitoring/assessment record states additionality was confirmed by the VVB using an investment test.
missing Baseline is project-specific and baseline reassessment timing is not stated; combined with multiple contradictions, this increases over-crediting risk.
Transparency
verified Key MRV elements are disclosed (methodology ACM0002 v22, grid emission factor 0.533, monitoring period 2022-05-01 to 2024-03-07, VVB named as Applus).
missing Claimed vs verified reductions differ materially (329,859 claimed vs 300,527 verified) and ERR figures conflict across documents.
Claim Safety
verified The project is explicitly not CORSIA-eligible, reducing certain downstream double-claiming/eligibility risks.
missing Contradictory ERR totals and inconsistent leakage justification increase the risk of over-crediting and weak defensibility of claims.
Documentation
verified A relatively large document set was used (19 documents including PDD, validation, monitoring, issuance) with high extraction confidence.
missing Numerous corrective actions (CAR-1 to CAR-18 and CAR-22) suggest documentation/MRV quality issues despite availability.
Detailed Analysis
Integrity
The monitoring/assessment record indicates additionality was confirmed by the VVB and framed as an investment test, which supports additionality for a renewable energy project. However, the baseline is described as project-specific and the timing of any baseline reassessment is not stated in the extracted record, which weakens baseline robustness. Leakage is applied as a 0% deduction, but the monitoring record is inconsistent on whether leakage was quantified or not addressed, reducing confidence in the completeness of the accounting. No reversal buffer is stated (and reversals are not relevant for an avoidance hydro project), but the large number of corrective actions signals process weaknesses that can affect integrity.
Transparency
The monitoring report (dated 2025-03-28) provides a clear monitoring period (2022-05-01 to 2024-03-07), identifies the VVB (Applus), and reports a grid emission factor of 0.533 under ACM0002 version 22. Transparency is reduced by the material gap between claimed and verified reductions in the extracted record (329,859 claimed vs 300,527 verified), indicating adjustments and potential MRV issues. Multiple contradictions across documents on key quantities (ERR totals, leakage justification, crediting period) further reduce the reliability of what is publicly reported.
Claim Safety
The project is marked as not CORSIA-eligible, which lowers the risk of certain eligibility-based marketing claims. Nonetheless, the emissions reduction numbers are inconsistent across documents, including very large discrepancies involving 827,828 versus the monitoring-period figures, which increases greenwashing/over-crediting risk if buyers rely on headline totals. Leakage justification is inconsistent across monitoring reports while applying a 0% deduction, which weakens defensibility of claims even if leakage is typically low for grid-connected renewables. CCP status is not stated in the extracted record, leaving uncertainty for high-integrity label claims.
Documentation
Documentation coverage appears relatively strong in breadth (19 documents including PDD, validation report, monitoring report, and issuance) and the minimum extraction confidence is high, suggesting the underlying files were readable. However, the presence of many corrective action requests (CAR-1 through CAR-18 and CAR-22) indicates that, despite document availability, the quality/completeness of evidence and MRV procedures required substantial remediation. Several social/safeguards items (FPIC, grievance mechanism, benefit sharing, safeguards mention) are contradictory across documents, suggesting inconsistent reporting rather than consistently documented safeguards.
Overall
Overall quality is mid-range because the project has a standard renewable energy methodology (ACM0002) and VVB-confirmed additionality, but data reliability is undermined by multiple contradictions and a large set of corrective actions. For the contradiction on claimed ERR (329,859 in a monitoring report dated 2022-12-06 vs 827,828 in a validation report dated 2021-06-18), the monitoring-period figure is privileged because it is tied to an actual monitored period rather than an ex-ante validation estimate; the discrepancy still lowers scores. For leakage justification (quantified in the 2022-12-06 monitoring report vs not addressed in the 2025-03-28 monitoring report), the more recent 2025-03-28 statement is privileged, implying weaker disclosure and lowering integrity/claim safety. For safeguards/FPIC/grievance/benefit sharing contradictions (monitoring report 2025-03-28 says present vs validation report 2024-11-29 says absent), the more recent monitoring report is privileged but treated cautiously because validation is typically the primary safeguards assessment; this inconsistency reduces transparency and documentation confidence. For additionality verification (PDD 2012-06-02 indicates not verified vs monitoring report 2025-03-28 indicates verified), the later third-party assessment is privileged because VVB confirmation occurs at validation/verification rather than in the PDD; the contradiction still signals record inconsistency. For crediting period (2014-03-08—2024-03-07 in a 2022-12-06 monitoring report vs 2024-03-08—2034-03-07 in the 2025-03-28 monitoring report), the later crediting period is privileged as the most recent statement, but the shift is significant and reduces confidence in registry/period clarity.
Audit Analysis
This is a grid-connected hydro renewable energy project under VCS with additionality presented as an investment test and a quantified grid emission factor, but several cross-document inconsistencies reduce confidence in the emissions reduction numbers and non-carbon safeguards narrative. The monitoring record shows a sizable gap between claimed and verified reductions and a large number of corrective actions, which increases over-crediting and MRV risk despite generally good document availability.
Project Description
The Aslancik Hydro Power Plant project in Turkey generated 93 MWe of emission-free electricity and supplied it to the national grid.
Red Flags
- Major inconsistencies in emissions reduction figures across documents (e.g., 329,859 vs 827,828) and in the verified total (300,527 vs 827,828), undermining confidence in credit quantities.
- Large number of corrective action requests (CAR-1 through CAR-18 and CAR-22) indicates material MRV/process weaknesses during assessment.
- Leakage treatment is inconsistent across monitoring reports (quantified vs not addressed) while a 0% leakage deduction is applied.

Cosa migliorerebbe questo punteggio
- Publish a reconciled ERR table that clearly separates ex-ante estimates from ex-post verified reductions for each monitoring period, and align all documents/registry entries to the same totals.
- Provide a consistent leakage assessment narrative (even if negligible) with explicit justification under ACM0002 and ensure it matches the applied 0% deduction.
- Resolve safeguards inconsistencies by publishing dated evidence of FPIC, grievance mechanism operation, and benefit-sharing arrangements, and ensure validation/monitoring reports reference the same evidence set.
Questi suggerimenti indicano quali prove pubbliche aggiuntive potrebbero migliorare il livello di confidenza di questa valutazione. Non garantiscono un punteggio futuro più alto.
