10.2MW Yangdun Small-Scale Hydropower Project

Audit Analysis

A 10.2 MW small-scale hydropower project in China under CDM with a 7-year crediting period. The project is a generation-type credit with inherently low permanence risk, but the available documentation contains four contradictions between the validation and monitoring reports (baseline method, leakage justification, ERR figures, and crediting start date), and the additionality test type is not stated in the extracted record. Only one monitoring period (6.5 months) is documented for the full crediting period, limiting the ability to verify long-term performance.

Project Description

Red Flags

• ⚠Additionality test type is not stated in any available document; the VVB (CEC) is identified but the specific test applied (investment, barrier, or regulatory) cannot be confirmed from the extracted record.
• ⚠Baseline method is contradictory: the validation report (2015) describes a jurisdictional baseline while the monitoring report (2016) describes a project-specific baseline, creating uncertainty about which baseline underpins the credit.
• ⚠Leakage justification is inconsistent: the validation report deems leakage negligible while the monitoring report states it was quantified, yet the deduction is 0% in both cases.
• ⚠Only one monitoring period (Sep 2015 – Mar 2016) is documented for a crediting period extending to July 2022, leaving roughly 6 years of the crediting period without verified monitoring data in the extracted record.
