Reference I-DEV0345
Submitted by TÜV SÜD (23 Sep 2010)
Project activity 840: Pansan Coal Mine Methane Utilisation and Destruction Project
Selected monitoring period 19 Sep 2008 - 21 Oct 2009
Title/subject of deviation Change of electricity meter not affecting the accuracy of the monitoring of the net flow of electicity.
Description
Electricity generaton: From the start of this monitoring period, two net electricity meters temporarily replaced the two bi-directional electricity meters in the Pansan substation to meter the production of the CMM-engines.The reason of replcaemnt is for meters’ routine maintenance.The new electricity meters only record net power supply,while ACM0008(Version 2) requires the separate monitoring of the consumed energy (CONSELEC,PJ ID P5 in section 11.2) and of the produced energy (GENy ID B46 in section 12.4)
Assessment
The deviation of the measurement of GENy and CONSELEC,PJ only apply to the given monitoring period. During the on-site audit, it was confirmed by the project participants and the audit team that GENy and CONSELEC,PJ have been monitored separately from 21 Oct 2009 onwards, which is in line with the requirement from ACM0008 V02 and the monitoring plan in the registered PDD. The deviation does not lead to any increas of the calculated emission reductions:the volume of emission reductions claimed is not affected by the deviation. Hence no amendment to the registered monitoring plan is required or proposed.
Impact
The estimate of the emission reductions for the proposed project is not affected by the deviation. The emission reduction calculation includes generation on one side and consumption on the other; therefore, reductions are calculated from the net flow of electricity multiplied by the grid emission factor. Therefore, the volume of emission reductions claimed is not impacted.
Overall emission reductions are calculated as baseline emission minus project emissions as following (there is no leakage for this project):

ERy = BEy – PEy with
BEy = BEMR + BEUSE and
PEy = PEME + PEMD + PEUM
The only two parameters including an electricity monitoring element are
BEUSE = GENy * CEFELEC and
PEME = CONSELEC * CEFELEC

Hence, regarding the power component, the overall emission reductions will be reduced to
BEUSE – PEME = GENy * CEFELEC - CONSELEC * CEFELEC which can be further reduced to

CEFELEC * (GENy – CONSELEC) with the part in brackets simply indicating the net electricity supply that is monitored as one parameter for the given monitoring period.
