5MW Thap Sakae Photovoltaic Solar Cell Power Plant Project, Thailand

Audit Analysis

A 5 MW solar PV project in Thailand registered under CDM with a jurisdictional grid-emission-factor baseline and VVB-confirmed additionality. The project's fundamental design is sound, but the verification process surfaced 14 material findings and 11 corrective actions covering grid-EF calculation errors, NCV value mistakes, and Build Margin omissions, indicating significant initial quality-control weaknesses that were subsequently remediated. Monitoring data is limited to a single 8-month period from 2017, and several key transparency fields (FNRB, usage monitoring, CORSIA/CCP status) are absent from the extracted record.

Project Description

Red Flags

• ⚠14 material findings and 11 corrective actions identified during verification, including errors in grid emission factor calculation, NCV values, fuel consumption data, and Build Margin exclusion of CDM-registered projects — all corrected but indicating weak initial QA/QC
• ⚠Total verified ERR (1,788 tCO2e for 8 months) is approximately 74% of the pro-rata expectation (~2,412 tCO2e) derived from the PDD lifetime estimate of 36,180 tCO2e over ~10 years, suggesting potential over-crediting in the ex-ante estimate or seasonal under-delivery
• ⚠No buffer pool percentage stated and no reversal events data available, leaving permanence risk unquantified despite the project being an avoidance-type credit
• ⚠Monitoring data is limited to a single 8-month period (Aug 2016 – Mar 2017) with no subsequent monitoring reports found in the extracted record
