Box 13: Exclusion of immaterial parts of a multinational grid<br />
Grids providing<br />
less than 1% of<br />
Project Grid can<br />
be neglected<br />
Data collection becomes cumbersome especially when the project power plant is<br />
connected to a multinational grid and the project boundary has to include all the<br />
CES connected to the PES. A request for revision of ACM0002 (version 06) sought<br />
to exclude parts of a multinational grid from which the PES imports power less<br />
than or equal to 1.0% of the total power consumption of the PES (i.e. immaterial<br />
parts of the multinational grid) ?? .The request for revision was accepted by EB 31<br />
and the revision is to be incorporated in the next version of ACM0002.<br />
Renewable Power<br />
Generation<br />
Determines<br />
Energy Baseline<br />
Baseline Scenario and Additionality<br />
The baseline is the annual power generated by the renewable unit multiplied<br />
by the emission coefficient of the grid that the project power plant is<br />
connected to.<br />
Additionality of the project shall be demonstrated by application of the latest<br />
version of the “Tool for the demonstration and assessment of additionality”<br />
(additionality tool).<br />
Baseline Emissions<br />
ACM0002 employs the CM approach for calculating the baseline emission<br />
factor to take into account the effects on OM and BM caused by the project.<br />
Operating Margin<br />
Operating Margin ACM0002 specifies four different methods to calculate the OM emission<br />
factor: (i) dispatch data analysis, (ii) simple OM, (iii) simple adjusted OM, and<br />
(iv) average OM. These methods can yield strongly different results and thus<br />
the choice of method is crucial for determination of CER volume.<br />
Emission Factor<br />
for Electricity<br />
Imports from<br />
other Grids<br />
Dispatch Analysis:<br />
Emission Factor of<br />
top 10% of Power<br />
Plants dispatched<br />
to the Grid<br />
In any case, net electricity imports from the CES within the same host<br />
country(ies) shall be considered as follows:<br />
• 0 tCO 2<br />
/MWh; or<br />
• The emission factor(s) of the specific power plant(s) from which power is<br />
imported, only if the specific plants are clearly known; or<br />
• The average emission rate of the exporting grid, only if the net imports do<br />
not exceed 20% of the total generation in the PES; or<br />
• The emission factor of the exporting grid determined based on the CM<br />
approach, if the net imports exceed 20% of the total generation in the<br />
PES.<br />
For imports from the CES located in another country, the emission factor shall<br />
be assumed to be 0 tCO 2<br />
/MWh.<br />
Dispatch data analysis: The dispatch data analysis should be the first<br />
choice if the necessary data (i.e. hourly dispatch data and dispatch order)<br />
is available. In this case, the OM emission factor is calculated as the hourly<br />
generation-weighted average emissions per power unit (tCO 2<br />
/MWh) of<br />
the set of power plants falling within the top 10% of the grid system<br />
dispatch order. Where the dispatch data analysis cannot be applied, project<br />
participants shall select any of the other three options subject to the<br />
