Audit Analysis
The Los Mina combined-cycle upgrade project has a VVB-verified additionality assessment and quantified leakage treatment, but is undermined by a 27.5% under-delivery against ex-ante estimates, an incorrect methane GWP value (21 instead of 28), and five outstanding corrective actions. The project-specific baseline and multiple documentation gaps in the verification report reduce confidence in the claimed reductions. Overall, the project is credible in design but shows meaningful execution and reporting weaknesses.
Red Flags
- Net GHG reductions are 27.51% lower than ex-ante estimates (1,144,395 vs 1,578,598 tCO2e) due to overestimated power generation and plant efficiency, per the verification report
- Incorrect GWP value applied for methane (21 instead of 28), which understates methane-related emissions by roughly 33%
- Five corrective actions remain open, including missing calibration certificates, PPA documentation, and stakeholder communication evidence
- Start date discrepancy between the verification and monitoring reports, and methodology deviation regarding fuel measurement units noted in the verification report
