Guangdong Shaoguan Yizhou Hydro Power Station

Audit Analysis

A CDM hydro project validated by TÜV NORD CERT with a confirmed investment additionality test and a jurisdictional grid-emission-factor baseline. The project is straightforward in design (displacing grid electricity with hydro generation), but four cross-document contradictions in key fields—baseline method, crediting period, additionality test type, and ERR figures—introduce moderate data-reliability concerns. No reversal events, no outstanding corrective actions, and a reasonable 0% leakage deduction for a hydro displacement project support overall integrity.

Project Description

Red Flags

• ⚠Baseline method is described as 'project' in the validation report (2009) but 'jurisdictional' in the monitoring report (2012); the grid emission factor of 0.84335 (2007) supports the jurisdictional reading, but the discrepancy is unexplained.
• ⚠Crediting period differs between the validation report (2008-11-01 to 2015-10-31) and the monitoring report (2009-03-24 to 2016-03-23), a shift of roughly four months at each end.
• ⚠The validation report notes that baseline emission-factor calculations required modifications to NDRC data due to identified mistakes in emission factors for coke and refinery gas, indicating the initial grid EF was not fully reliable.
• ⚠Verified ERR figure for the monitoring period (2010-11-01 to 2012-03-31) was not found in the extracted record, preventing a direct pro-rata delivery check against the 59,346 tCO₂e lifetime claim.
