Renoe Acipayam Solar Power Plant

Audit Analysis

The Renoe Acipayam Solar Power Plant is a Gold Standard solar thermal project in Turkey with a VVB-verified combined additionality test and a project-specific baseline reassessed in 2023. However, the project carries significant data-reliability concerns: 40+ corrective actions were required before issuance, multiple ERR figures contradict across monitoring and verification reports, and no buffer pool percentage is stated. The first monitoring period shows a 352% over-delivery relative to the pro-rata ex-ante expectation, which, while potentially explainable by seasonal solar peaks, warrants scrutiny given the surrounding data inconsistencies.

Project Description

Red Flags

• ⚠40+ corrective actions and 24 CARs were required before credit issuance, indicating substantial documentation and calculation quality issues in both the PDD and Monitoring Report
• ⚠Two monitoring reports (Feb 2025 and Nov 2025) report claimed ERRs of 19,007 and 4,391 tCO2e respectively — a 4.3× discrepancy that, even if attributable to different periods, signals data-management weakness
• ⚠Baseline method is contradictory: the 2024 verification report describes a project-specific baseline while the 2023 verification report references a jurisdictional baseline
• ⚠Verified ERR of 19,007 tCO2e for a 5-month period is 352% of the pro-rata ex-ante expectation (5,407 tCO2e), raising questions about the conservatism of the ex-ante estimate or the accuracy of the monitoring calculation
