DEWA Chiller Station L

Audit Analysis

DEWA Chiller Station L is a CDM energy-efficiency project with VVB-confirmed additionality (barrier test) and a measured project-specific baseline, verified by TÜV NORD CERT. The project shows no reversal events and a quantified 0% leakage deduction, but the ERR figures differ between the PDD (268,000 tCO₂e) and the monitoring report (331,545 tCO₂e), and several key parameters (fnrb, usage rates, baseline reassessment timing) are not stated in the available documents. Overall a moderately well-documented project with some data gaps and one notable quantitative discrepancy.

Project Description

Red Flags

• ⚠ERR discrepancy: the PDD (2016) estimates 268,000 tCO₂e while the monitoring report (2023) reports 331,545 tCO₂e for the 2015–2020 period; the pro-rata expectation for 6 of 10 crediting years is ~160,800 tCO₂e, meaning the reported figure is roughly 206% of the pro-rata baseline estimate, which warrants scrutiny of the baseline or calculation methodology.
• ⚠Leakage justification is inconsistent across documents: the validation report (2012) characterises leakage as 'deemed negligible' while the monitoring report (2023) states it was 'quantified', yet both arrive at a 0% deduction without a clearly documented quantification method.
• ⚠No fnrb method or value, no usage-rate assumption or verification, and no baseline reassessment date are found in the extracted record, leaving key MRV parameters unverified.
