Ningxia Lingwu Baitugang 40MWp Solar PV Power Generation Project

Audit Analysis

A 40 MWp grid-connected solar PV project in Ningxia, China, verified under Gold Standard with a VVB-confirmed combined additionality test and no reversal events. However, the verified emissions reduction for the latest monitoring period is only about 44% of the pro-rata annual expectation derived from the ex-ante lifetime estimate, leakage is deducted at 0% with no stated justification, and the verification report flagged material findings including an incorrect electricity-generation calculation and incomplete calibration coverage. These issues collectively moderate confidence in the project's additionality robustness and claim accuracy.

Project Description

Red Flags

• ⚠Verified ERR of 19,127 tCO₂e is only ~44% of the pro-rata annual expectation (~43,229 tCO₂e) derived from the 302,603 tCO₂e ex-ante lifetime estimate over a 7-year crediting period, suggesting significant under-delivery or an over-optimistic baseline
• ⚠Leakage deduction of 0% with the justification recorded as 'not addressed' in the 2023 verification report, contradicting the 2020 verification report which described it as 'quantified'
• ⚠Material finding CAR#2 states the calculation of net electricity generation supplied to the grid is incorrect, and CAR#1 notes calibration of monitoring instruments does not cover the full monitoring period
• ⚠Baseline method is contradictory: the 2020 verification report records 'project' while the PDD records 'jurisdictional', creating ambiguity about the baseline basis
• ⚠Grid emission factor changed from 0.767425 (PDD, 2020) to 0.8568 (verification report, 2023) without a documented explanation of the update rationale
