Gansu Anxi Wind Farm Project, 100.5 MW

Audit Analysis

The Gansu Anxi Wind Farm is a 100.5 MW wind project under Gold Standard with VVB-confirmed additionality and a 14-year crediting period, but its integrity is undermined by a project-specific baseline, a 0% leakage deduction with contradictory justifications across documents, and 14 material findings including a 35% discrepancy between the actual plant load factor and the PDD estimate. Data quality issues (calibration gaps, rounding errors, inter-document inconsistencies) and low extraction confidence further erode confidence in the MRV chain, though the project is over-delivering relative to its pro-rata ex-ante expectation, reducing over-crediting risk.

Project Description

Red Flags

• ⚠Plant load factor of 16.85% in the monitoring report is 35% lower than the 26% estimated in the PDD, indicating the PDD's generation assumptions were poorly calibrated
• ⚠Leakage justification is contradictory: the 2015 verification report states it was 'quantified' while the 2015 monitoring report states it was 'not addressed', yet the deduction is 0%
• ⚠14 material findings were logged across verification and monitoring reports, including calibration data not transparently presented, data discrepancies between monitoring logs and grid transaction notes, and multiple inter-document inconsistencies
• ⚠Grid emission factor increased from 0.85688 (PDD) to 0.99685 (2013, verification report), a 16% increase that inflates credits per MWh relative to the original PDD basis
• ⚠Min extraction confidence is rated low, indicating at least one key document was poorly readable, reducing reliability of the extracted record
