CDM Project of Moinho and Barracão Small Hydropower Plant

Audit Analysis

A small hydropower project in Brazil validated under CDM methodology ACM0002 v7 with a VVB-confirmed investment additionality test and a jurisdictional baseline. The project is structurally sound for its type, but the available record is limited to validation-stage documents with no verified emission reduction figures, a low extraction confidence rating, and two inter-document contradictions that reduce confidence in the data. All four material findings raised by TÜV NORD CERT were addressed with corrective actions, but the 2007 grid emission factor and the absence of monitoring-period verification data leave the actual delivery unconfirmed.

Project Description

Red Flags

• ⚠No verified emission reduction figure (total ERR verified) was found in any available document, making it impossible to confirm actual delivery against the 107,909 tCO₂e lifetime claim.
• ⚠The grid emission factor of 0.1842 tCO₂/MWh is from 2007 and was subject to a revision decision by Brazil's DNA, as flagged in the validation report's material findings.
• ⚠Min extraction confidence is rated low, indicating at least one key document was poorly readable, which undermines confidence in the extracted data.
• ⚠The investment analysis for the Barracão plant was initially missing and only provided as a corrective action, raising a question about the completeness of the original additionality evidence.
