Tailai Tangchi Solar PV Power Generation Project

Audit Analysis

A Gold Standard grid-connected solar PV project in China with VVB-confirmed additionality and a reasonable 0% leakage deduction for its project type. However, significant contradictions across documents—particularly on baseline method, leakage justification, and FPIC status—undermine confidence in the data record, and the absence of a verified ERR figure prevents a meaningful claim-safety assessment.

Project Description

Red Flags

• ⚠Baseline method is contradictory: the 2023 verification report labels it 'project' while the 2022 validation report calls it 'jurisdictional'; for a grid-connected solar PV project the baseline should be the jurisdictional grid emission factor, making the 'project' label in the more recent document inconsistent with the methodology (AMS I.D.).
• ⚠Leakage justification is inconsistent: the 2023 verification report states leakage was 'not addressed' while the 2022 verification report says it was 'deemed negligible'; the 0% deduction is reasonable for grid-connected solar but the lack of a consistent, explicit justification in the most recent document is a gap.
• ⚠FPIC status is directly contradictory: the monitoring report (Oct 2020) records FPIC as conducted, while the PDD (same date) records it as not conducted; this cannot be resolved without further documentation.
• ⚠No verified ERR figure was found in the extracted record, preventing any comparison of claimed versus delivered credits for the 2024 monitoring period.
