Baofeng County Waste Heat Recovery for Power Generation

Audit Analysis

A CDM waste-heat-recovery project for a cement plant with a verified combined additionality test, but significant baseline validity concerns: the monitoring report revealed the electricity is supplied captive to the cement plant rather than exported to the grid as described in the PDD, the grid emission factor dates to 2005, and leakage is treated as 0% with contradictory justifications across documents. The ERR figures in the two key documents (41,244 vs 436,120 tCO₂e) are on different bases (monitoring period vs lifetime estimate), but the discrepancy was not clearly reconciled in the extracted record.

Project Description

Red Flags

• ⚠Material finding: electricity is supplied directly to the cement plant (captive), not delivered to the grid as described in the PDD — this fundamentally changes the baseline scenario and was only clarified during validation (CL 1, CL 6).
• ⚠Leakage justification is contradictory: the validation report (2008) states leakage is 'deemed negligible' while the monitoring report (2010) records it as 'not addressed'; the 0% deduction lacks a consistent, documented rationale.
• ⚠Grid emission factor of 0.9746 tCO₂/MWh is from 2005, making the baseline reference value over a decade old at the time of the monitoring report.
• ⚠No buffer pool or permanence mechanism is documented for this project, leaving no safeguard against potential reversal of credits.
• ⚠Equipment capacities (boilers, turbine, generator) changed from the registered PDD specifications, and meter accuracy classes and calibration frequencies differ from what was originally approved.
