Ventus Wind Farm in El Salvador

Audit Analysis

The Ventus Wind Farm has a solid additionality foundation confirmed by the VVB and no reversal events, but is undermined by an extensive list of material findings spanning multiple verification cycles, including calculation errors in emission factors, non-compliant project scale, and inconsistent ERR figures across documents. The low extraction confidence and multiple contradictions between the validation, monitoring, and verification reports raise significant data-reliability concerns that limit confidence in the claimed reductions.

Project Description

Red Flags

• ⚠Thirteen material findings across verification cycles, including errors in heat rate, electricity imports (LCMR), project scale non-compliance with VCS rules, and crediting period not fixed at 10 years as required by TOOL23
• ⚠ERR figures inconsistent between the 2020 validation report (103,593 tCO2e lifetime) and the 2025 verification report (85,182 tCO2e), with the monitoring period showing 22.3% under-delivery while Year 2 reportedly exceeded ex-ante by 32%
• ⚠Four wind turbines (WTG 01, 04, 12, 13) were offline for most of 2022 due to lightning damage, and WTG05 had an unassessed outage from Dec 2024 to Apr 2025, yet the verification still issued credits
• ⚠Meter calibration frequency was not met for November 2021, requiring a 0.2% correction factor, and calibration scope issues persisted into the 2025 monitoring report
• ⚠min_extraction_confidence is rated 'low', indicating at least one key document was poorly readable, reducing confidence in the extracted data
