75MW Yunnan Nuozu Hydropower Project

Audit Analysis

The 75MW Yunnan Nuozu Hydropower Project is a fundamentally sound CDM hydro design with a jurisdictional grid baseline and VVB-verified combined additionality test, but its integrity is undermined by five corrective actions and twelve material findings at validation, including inaccurate IRR sensitivity calculations and a non-conservative electricity estimate. Key verification data (verified ERR, FNRB, monitoring method) are absent from the extracted record, limiting transparency. The project delivered roughly 139% of its pro-rata expectation for the 2013–2015 monitoring period, suggesting no over-crediting, but the documentation quality issues and missing safeguards records prevent a higher rating.

Project Description

Red Flags

• ⚠Five corrective actions were required at validation, including inaccurate sensitivity analysis in the IRR spreadsheet and a non-conservative annual electricity delivered value in the PDD
• ⚠The latest additionality tool was not applied for the common-practice analysis at the time of validation
• ⚠No verified ERR figure, FNRB value, or usage monitoring method is available in the extracted record
• ⚠Crediting period start date differs by 11 days between two monitoring reports (2013-01-01 vs 2012-12-21)
