Guangxi Bajiangkou Hydropower Project

Audit Analysis

The Guangxi Bajiangkou 90 MW hydropower project demonstrates solid additionality (IRR without CERs of 6.76% well below the Chinese hurdle rate) and a jurisdictional grid-emission-factor baseline, with verified emissions reductions closely matching claimed values (99.1% delivery). The main concerns are a contradiction in baseline method characterization between the 2011 and 2012 monitoring reports, and the absence of leakage treatment in the original validation report. Overall, this is a well-documented CDM hydro project with moderate data inconsistencies that do not fundamentally undermine the credit claims.

Project Description

Red Flags

• ⚠Baseline method described as 'project-specific' in the 2011 monitoring report but 'jurisdictional' in the 2012 monitoring report — the more recent 2012 characterization is privileged, but the inconsistency raises questions about baseline robustness
• ⚠The 2008 validation report did not address leakage at all; the 2012 monitoring report later deemed it negligible with a 0% deduction, leaving a gap in the original validation record
• ⚠CORSIA eligibility and CCP status are not stated in any available document, leaving dual-channel risk unassessed
