Analysis

The Lihir Geothermal Power Project is a CDM-registered geothermal facility in Papua New Guinea with VVB-confirmed additionality and a reasonable leakage treatment for a grid-connected renewable energy source. However, the project-specific baseline (last reassessed in 2005), a grid emission factor drawn from 2004 data, and a delivery rate of roughly 78% of the pro-rata ex-ante expectation introduce moderate over-crediting risk. Documentation is reasonably complete (17 sources, high extraction confidence) but eight material findings and two corrective actions flag PDD quality issues.
