Biomass power

A biomass power plant which consists of a biomass boiler, a generator

plant

set (genset) and auxiliary equipment. The biomass boiler generates
heat by combusting biomass resources as its fuel, and the genset uses
the heat to generate electricity.

Biomass resources

Biomass resources refer to non-fossilized, biodegradable organic
material originating from naturally occurring or cultured plants,
animals and micro-organisms, including agricultural products, byproducts and residues such as, but not limited to, biofuels except corn,soya beans and rice but including sugarcane and coconut, rice hulls,
rice straws, coconut husks and shells, corn cobs, corn stovers, bagasse,
biodegradable organic fractions of industrial and municipal wastes thatcan be used in bioconversion process and other processes, as well asgases and liquids recovered from the decomposition and/or extractionof non-fossilized and biodegradable organic materials.

project Project emissions are calculated from emissions from onsiteemissions

fossil fuel consumption for processing biomass resources andassisting combustion of biomass resources, and emissions fromfossil fuel consumption for transportation of biomass resources.
In case there is the evidence that demonstrate transportation
distance of biomass resources does not exceed 200km, emissions
from transportation can be neglected.

Monitoring parameters- Net amount of electricity generated by a biomass power plant- The amount of onsite fuel consumption for processing biomass
resources and assisting combustion of biomass resources- The amount of fuel consumption for transportation of biomass

D. Eligibility criteria

This methodology is applicable to projects that satisfy all of the following criteria.
Criterion 1

A biomass power plant is installed and supplies electricity to the national grid
and/or regional electric cooperatives.
In case a biomass power plant provides generated electricity to regional
electric cooperatives only, or to both national grid and regional electricCriterion 2

cooperatives, CO2 emission factor for the national grid is more conservative
than that of regional electric cooperatives, through comparing those energy
mixes.

Criterion 3

Biomass resources from dedicated plantation are not used in the project.

CO2F. Establishment and calculation of reference emissions
F.1. Establishment of reference emissions
Reference emissions are calculated based on the net amount of electricity generated by abiomass power plant and CO2 emission factor for the national grid.
In general, auxiliary equipment of a biomass power plant, when in operation, consumes
electricity generated by the power plant itself, however, all the auxiliary equipment is notalways in operation, nor do they operate at maximum load. To ensure conservativeness in thismethodology, it is assumed that all the auxiliary equipment operates all the time at theoreticallymaximum load during a given monitoring period. Hence, the net amount of electricity
generated by the biomass power plant can be calculated lower than that of the actual case,which leads to net emission reductions.
