Audit Analysis
The Hamal Solar Power Project is a Gold Standard solar thermal electricity project in Turkey with a verified combined additionality test and a jurisdictional baseline, but it is undermined by an extensive list of over 50 corrective actions, multiple contradictions between verification reports issued just days apart, and a low extraction confidence rating. The project was retroactively registered from CDM, and while the claimed and verified emission reductions match at 18,098 tCO₂e, a parallel report from eight days earlier states only 9,501 tCO₂e, raising material concerns about calculation reliability.
Red Flags
- Two verification reports issued eight days apart (2025-12-10 and 2025-12-18) report materially different verified ERR values (9,501 vs 18,098 tCO₂e) and different grid emission factors (0.5676 vs 0.6488), indicating unresolved calculation or scope discrepancies.
- Over 50 corrective actions were issued by the VVB, including errors in emission factor values, ER calculations, monitoring period dates, and missing data in the ER calculation spreadsheet, signalling systemic MRV quality problems.
- The project was originally a CDM project applying for retroactive Gold Standard registration, and the crediting period in the earlier report (2018–2023) is entirely different from the current period (2023–2028), suggesting a gap or overlap risk.
- Minimum extraction confidence is rated low, meaning at least one key document was poorly readable, reducing reliability of the extracted data.
