Thuan Nhien Phong Wind Farm

Audit Analysis

The Thuan Nhien Phong Wind Farm is a Gold Standard wind project with a verified investment additionality test and a reasonable 0% leakage deduction, but the verification report surfaced 14 material findings and 15 corrective actions, including a striking reference to 'lower sun hours' as a justification for under-delivery in a wind project. The project delivered 42,158 tCO₂e in 2024, which is above the pro-rata expectation derived from the 2021 lifetime estimate, yet the sheer volume of data-quality issues and the unresolved baseline-method contradiction undermine confidence in the underlying calculations.

Project Description

Red Flags

• ⚠The verification report justifies 51% lower-than-estimated emissions reductions by citing 'lower sun hours and curtailment' — a solar-specific explanation applied to a wind project, indicating a probable template or copy-paste error that undermines trust in the MRV narrative.
• ⚠14 material findings and 15 corrective actions were raised in the 2025 verification report, spanning inconsistent energy values, missing parameters, baseline misalignment, and unexplained operational status of 3 out of 8 wind turbines.
• ⚠FPIC was not conducted, despite the project being registered under Gold Standard, which expects free, prior, and informed consent for affected communities.
• ⚠The baseline method is contradictory across documents: the 2024 verification report describes a 'project' baseline while the 2025 monitoring report describes a 'jurisdictional' baseline, leaving the actual calculation basis ambiguous.
• ⚠Minimum extraction confidence across the document set is rated 'low', and one evidence document is listed as 'unknown', reducing reliability of the extracted record.
