Grid connection of an isolated electricity system on the Pacific Coast of Colombia (Cauca – Nariño)

Audit Analysis

A CDM grid-connection project in Colombia with VVB-confirmed additionality and quantified leakage, but undermined by two significant data contradictions (grid emission factor and total ERR), the absence of any verified ERR figure, and a low extraction confidence rating that limits trust in the extracted record. The 48 closed corrective action requests and an open SF6 monitoring concern further temper confidence in implementation quality.

Project Description

Red Flags

• ⚠Grid emission factor appears as 0.1031 tCO₂/kWh in the validation report but 0.5913 tCO₂/kWh in an appendix — a 5.7× discrepancy that, if unresolved, directly affects the magnitude of claimed reductions
• ⚠Total ERR is 297,183 tCO₂ in the validation report versus 42,455 tCO₂ in the PDD — a 7× gap that may reflect an annual-vs-lifetime basis difference (42,455 × 7 ≈ 297,183) but is not explicitly reconciled in the available documents
• ⚠No verified ERR figure was found in any of the six extracted documents, leaving the claimed reductions unvalidated against actual monitoring results
• ⚠48 Corrective Action Requests were raised during validation (all closed), indicating substantial implementation or documentation deficiencies at the time of validation
• ⚠A Forward Action Request regarding SF6 emissions monitoring remained open, with a corrective action to verify the monitoring plan during first verification
