Three Gorges New Energy Jiuquan Co., Ltd Guazhou 100MW Solar Power Project

Audit Analysis

A 100 MW solar PV project under VCS methodology ACM0002 with a jurisdictional grid-emission-factor baseline and a VVB-confirmed combined additionality test. The project delivers close to its pro-rata expectation (≈99%), but the verification record contains multiple material findings, eight corrective actions, and several cross-document contradictions that erode confidence in data quality and documentation rigour.

Project Description

Red Flags

• ⚠The 2022 verification report applied a 2 % materiality threshold instead of the 5 % required for projects with ER ≤ 300,000 tCO₂e/yr, meaning some errors may have gone undetected.
• ⚠Eleven material findings and eight corrective actions were raised across verification cycles, including inconsistent energy values between the monitoring report and meter records, and a calibration-validity gap in MR v01.
• ⚠The crediting period is stated as 2013-2023 (10 yr) in the 2022 verification report but 2012-2032 (20 yr) in a 2015 document, creating ambiguity about the project's actual crediting window.
• ⚠Leakage justification shifted from 'quantified' (2020 verification) to 'deemed negligible' (2022 verification) without a clear documented rationale for the change.
• ⚠Minimum extraction confidence is rated low, indicating at least one key document was poorly readable during data extraction.
