Hua'an Xipi Hydropower Project

Audit Analysis

The Hua'an Xipi run-of-river hydropower project (CDM-1275) displaces grid electricity and has a confirmed investment-test additionality verified by JACO CDM. However, the project-specific baseline, a 0% leakage deduction with inconsistent justification across documents, and a significant discrepancy in claimed ERR figures between two monitoring reports (116,161 vs 160,788 tCO2e) introduce moderate uncertainty. The project is a closed CDM registration with no buffer pool, no reversal events, and a fixed 2008 grid emission factor appropriate for the crediting period.

Project Description

Red Flags

• ⚠Claimed ERR differs by approximately 38% between the 2010 monitoring report (160,788 tCO2e) and the 2011 monitoring report (116,161 tCO2e), with no documented explanation for the revision
• ⚠Leakage justification is inconsistent: the validation report (2007) states 'deemed negligible' while the 2012 monitoring report states 'quantified', yet the deduction remains 0% in both cases
• ⚠Three corrective actions were required at validation, including a change to the coal consumption rate for Build Margin calculation (320 gce/kWh) and a revision to the monitoring plan for grid connection mode
• ⚠Baseline method is described as 'project-specific' in the 2012 monitoring report but 'jurisdictional' in the PDD, creating ambiguity about the actual baseline construction
