CDM Process
•
Verification 1 –
3•
Installation didn’t match Methodology
•
Installation did not match PDD•
Preliminary audit did not pick up either
•
DOE’s
were pedantic about process•
Monitoring report and plan were sophisticated and complex
•
Reports generated from the system•
Communication and back ups
CDM Process
•
Unable to change PDD•
Unable to change installation retrofit
•
Process -
Request for Deviation from UNFCCC•
Process took approximately 6 months
CDM Process
•
Verification 4 –
6•
New DOE appointed
•
New Criteria•
New criteria from EB
•
Request for deviation does not apply•
Re-submit Request for Revision
•
Change Hardware•
Change PDD
•
Change Monitoring Report and Monitoring Plan•
Revision completed 14 months April 2011
•
Verification 4 Completeness check
CDM Process
•
Verification 7 onward•
Template change for Monitoring Report
•
EB requirements change•
DOE requirements change
•
Process change and focus
Summary
•
Achieved Greenhouse Gas Reduction•
Stack Emissions clear
•
