GS1354 Vietnam Small Hydro PoA - Ta Trach Hydropower Project

Audit Analysis

The Ta Trach small hydro project has a VVB-verified investment additionality test and no reported reversal events, but is undermined by the absence of FPIC (per the 2022 PDD), a 0% leakage deduction supported only by a thin 'quantified' label, a project-specific baseline, and an unusually high volume of 34 corrective actions that reveal widespread documentation and calculation inconsistencies. Seven cross-document contradictions—including a 3.3× discrepancy in claimed ERR and conflicting FPIC status—further erode confidence in the project's data integrity.

Project Description

Red Flags

• ⚠FPIC was not conducted per the 2022 PDD (contradicting the 2020 PDD which stated it was), a critical safeguard gap for a hydro project in Vietnam
• ⚠34 corrective actions were required, spanning calculation errors, regulatory misreferences, and document misalignments, indicating substantial initial documentation weakness
• ⚠Claimed ERR of 312,275 tCO2e (2023) contradicts the 2020 PDD figure of 93,814 tCO2e — a 3.3× discrepancy with no verified ERR available to adjudicate
• ⚠0% leakage deduction justified only by the label 'quantified' without a visible quantitative methodology in the extracted record
