Large scale grid connected solar PV Project in Toujounine (Nouakchott)

Audit Analysis
A grid-connected solar PV project in Mauritania with a well-established methodology (ACM0002) and VVB-confirmed additionality, but undermined by significant operational issues (25 burned-out inverters, uncalibrated backup meter), numerous documentation inconsistencies across verification reports, and a project-specific baseline that lacks the robustness of a jurisdictional approach. The project is fundamentally low-risk in terms of permanence (avoidance type), but the volume of corrective actions and data quality concerns temper confidence in the reported figures.
Red Flags
- 25 inverters burned out due to grid overvoltage; 8 repairs still in progress at time of verification, creating underperformance and measurement uncertainty
- Backup meter PM5560 not calibrated; readings adjusted for 0.2% precision range, introducing measurement uncertainty into ER calculations
- Baseline method contradicts between the 2024 verification report (jurisdictional) and the 2025 verification report (project-specific), raising questions about which baseline was actually applied
- Project start date inconsistent across documents (2018-01-12 vs 2017-11-07), affecting crediting period calculations
- No FPIC conducted despite safeguards being mentioned; grievance mechanism present but community engagement documentation is absent
