Hainan Nansheng Bundled Small Hydropower Project

Audit Analysis

A CDM small-hydropower project in Hainan, China, validated by RINA in 2012 under AMS-I.D v17. Additionality was confirmed via a combined test, but the validation process surfaced five material findings—including a roughly seven-fold over-estimation of electricity generation in the original PDD and missing reservoir-emission calculations—that required corrective action before approval. The project is past its crediting period (ended March 2019) and no monitoring reports are available in the extracted record, leaving actual performance unverified.

Project Description

Red Flags

• ⚠The PDD claimed 119,756 tCO2 of emissions reductions while the validation report approved only 17,108 tCO2 — a roughly 7× discrepancy that indicates the initial project design significantly over-estimated generation for Maodao I, II, and Yachong.
• ⚠Five material findings were identified during validation, including missing Letters of Approval from both the host and Annex I Party DNAs, an outdated emission-factor calculation tool, and inconsistent technology descriptions (river-bed vs. diversion) between the PDD and PDRs.
• ⚠No monitoring reports, closure report, or post-validation documents are present in the extracted record; the project's actual performance over its 7-year crediting period is unverified.
• ⚠The grid emission factor of 0.765 tCO2/MWh is anchored to 2010 data, and no baseline reassessment or updated factor is documented for the remainder of the crediting period.
