Angang Sinter Machine Waste Heat Recovery and Generation Project

Audit Analysis

A standard CDM waste-heat-recovery project in China with a well-verified investment-test additionality assessment by DNV, but weakened by a 0% leakage deduction whose justification is inconsistent across monitoring reports, a grid emission factor frozen at 2006 values, and several unresolved documentation gaps (no verified ERR figure, no usage-monitoring method stated). The project is mid-crediting-period with no reversal risk, and all material findings from validation have been resolved.

Project Description

Red Flags

• ⚠Leakage deduction is 0% and the justification is contradictory: the January 2012 monitoring report describes it as 'quantified' while the September 2012 monitoring report states it was 'not addressed' — the later document is privileged, leaving the 0% figure without a clear, documented rationale.
• ⚠Grid emission factor of 0.9746 tCO₂/MWh is drawn from 2006 NDRC data (published August 2007) and has not been updated in the available documents, creating a risk that the baseline overstates or understates actual grid emissions over the full 2008–2018 crediting period.
• ⚠Installed capacity of major equipment (boilers, steam turbine, generator) differed from the PDD description, and nominal generation capacity changed from 20 MW to 26.55 MW during validation; although resolved, this indicates the initial project design documentation was imprecise.
