Audit Analysis
The Kayonza District Borehole Project in Rwanda is a Gold Standard energy-efficiency project with VVB-confirmed additionality and no reported reversals, but it is undermined by significant contradictions across key parameters (FNRB value, leakage deduction, crediting period) and the absence of a verified ERR figure. The project-specific baseline and unresolved leakage treatment create moderate over-crediting risk, while the 2017 borehole breakdowns, though resolved, highlight operational fragility.
Red Flags
- Crediting period contradiction: the 2021 monitoring report references 2015–2022 while the 2025 validation report references 2025–2030, leaving the 2023–2024 monitoring period in a regulatory gap
- FNRB value discrepancy: 0.98 in the 2021 monitoring report versus 0.85 in the 2023 PDD, implying up to ~15% over-crediting if the higher value is used
- Leakage deduction contradiction: 0% in the 2021 monitoring report versus 5% in the 2023 PDD, with the validation report (2025) not addressing leakage at all
- Total ERR verified is not stated in the extracted record, preventing any pro-rata delivery check
