Guizhou Zhenyuan Putian Hydropower Station

Audit Analysis

A small-scale CDM hydro project (AMS-I.D.) with a jurisdictional baseline and 100% verified ERR delivery over its full seven-year crediting period. However, two material findings in the validation report — a non-compliant PDD form version and a grid emission factor not aligned with the latest China DNA data — introduce meaningful uncertainty into the credit quantity. Low extraction confidence and several missing data points (additionality test type, safeguards detail, CORSIA/CCP status) limit the depth of assurance available.

Project Description

Red Flags

• ⚠Material finding: the grid emission factor (EFgrid,CM,y) was not calculated in accordance with the latest data from the China DNA, directly affecting the ER calculation
• ⚠Material finding: the PDD did not comply with the latest CDM-SSC-PDD-FORM version 6.0, indicating a documentation compliance gap at validation
• ⚠Contradiction between the PDD (leakage 'deemed negligible') and another document (leakage 'quantified') on the same date, creating ambiguity in the leakage treatment
• ⚠Additionality test type and VVB confirmation of additionality are not stated in the extracted record, leaving the additionality assessment unverifiable from available data
