OUARZAZATE IV CONCENTRATED SOLAR POWER PROJECT

Audit Analysis

The Ouarzazate IV CSP project is a registered VCS renewable energy project with VVB-confirmed additionality and reasonable leakage treatment, but the 2025 verification report surfaced seven material findings and thirteen corrective actions, including a meter calibration error exceeding permissible limits and a 32% gap between claimed and verified emissions reductions. The baseline method is inconsistently reported across verification cycles, and the low extraction confidence in the document set limits assurance on the completeness of the record.

Project Description

Red Flags

• ⚠Calibration error of −0.24% in energy meters exceeded the permissible ±0.2% limit, requiring a cumulative correction factor of up to −0.48% on net electricity generation (verification report, 2025).
• ⚠Verified ERR of 364,332 tCO₂e is only 68% of the 538,480 tCO₂e claimed by the project for the same 2020–2023 monitoring period, indicating a material over-claim in the monitoring report.
• ⚠Baseline method is reported as 'project-specific' in the 2025 verification report but as 'jurisdictional' in the 2022 verification report — an unresolved contradiction that affects baseline credibility.
• ⚠Thirteen corrective actions were required by the VVB, spanning ERR calculation methodology, grid emission factor consistency, meter identification, and stakeholder communication documentation.
• ⚠Minimum extraction confidence across the 13-document evidence set is rated low, reducing assurance on the completeness of the extracted record.
