Goods Production<br />
If a cogeneration plant is the baseline scenario, the electricity and heat uses<br />
are added up and multiplied by the plant efficiency, estimated in the same<br />
way as described above, with the default efficiency set at 90%. Discount<br />
factors for the share of energy produced from waste gas and pre-to post<br />
project waste gas generation are applied as well.<br />
Direct fuel use or indirect fuel use due to application of steam for flaring of<br />
waste gas is also included in baseline emissions.<br />
Project emissions<br />
Project emissions are emissions due to combustion of auxiliary fuel, emissions<br />
due to consumption of electricity for cleaning of waste gas before use<br />
and other electricity use by the project plant. If electricity is supplied from<br />
the grid, a default factor of 1300 g CO 2<br />
/kWh or ACM 0002 can be used.<br />
AMS I.D is eligible if electricity supply is less than 60 GWh. For captive<br />
power production, the default factor of 1.3 t CO 2<br />
/MWh or the actual plant<br />
emissions factor can be used.<br />
Leakage<br />
There is no leakage calculation.<br />
Monitoring<br />
Monitoring shall be conducted on the following items:<br />
Ex ante<br />
• Waste gas produced, preferably in the last 3 years but at least for 1 year<br />
• Steam used to flare waste gas produced, preferably in the last 3 years but<br />
at least for 1 year<br />
• Boiler load-efficiency functions, if this option is chosen for baseline<br />
determination. Measurement is based on recognized standards for the<br />
measurement of the element process efficiency, such as the “British<br />
Standard Methods for Assessing the thermal performance of boilers for<br />
steam, hot water and high temperature heat transfer fluids” (BS845) and<br />
to be done for at least 10 different load levels.<br />
• Production of good which most logically relates to waste gas generation<br />
(average of last 3 years)<br />
Ex post:<br />
• Waste gas used by the project<br />
• Power generation by the project differentiated according to recipients<br />
• Heat generation by the project differentiated according to recipients<br />
• Heat rate of waste gas<br />
• Fossil fuels burned in the project and their emission factors differentiated<br />
according to fuel type<br />
• Electricity grid emission factor according to applicable methodology (ACM<br />
0002 or AMS I.D)<br />
• Electricity consumption for gas cleaning equipment<br />
