Biomass power plant

Definitions
A biomass power plant, which consists of a biomass boiler, agenerator set (genset) and auxiliary equipment. The biomass
boiler generates heat by combusting biomass as its fuel, andthe genset uses the heat to generate electricity.

Biomass

Biomass is non-fossilized and biodegradable organic material
originating from plants, animals and microorganisms. This shall
include products, by-products, residues and waste fromagriculture, forestry and related industries as well as the nonfossilized and biodegradable organic fractions of industrial andmunicipal wastes. Biomass also includes gases and liquids
recovered from the decomposition of non-fossilized andbiodegradable organic material.

Biomass residue

Biomass residues are defined as biomass that is a by-product,residue or waste stream from agriculture, forestry and relatedindustries. This shall not include municipal waste or otherwastes that contain fossilized and/or non-biodegradable material(however, small fractions of inert inorganic material like soil orsands may be included).

Biomass boiler

A boiler which combusts biomass fuel to heat water and produce
steam.

Recipient facility

A facility (e.g., building, plant, etc.) or a cluster of facilities towhich electricity generated by a biomass power plant issupplied.

C. Summary of the methodology
Items

Summary

GHG emission reduction GHG emission reductions can be achieved through themeasuresdisplacement of grid and/or captive electricity by installation andoperation of a biomass power plant.

Calculation of reference Reference emissions are calculated from net electricity
emissionsgenerated by a biomass power plant multiplied by a CO2
emission factor for grid electricity or captive electricity.

Calculationof

project Project emissions include the emissions from combustion ofemissions

biomass fuels in a biomass power plant, the emissions fromcombustion of fossil fuel at a biomass power plant and theemissions from transportation of biomass residues.
[Emissions from biomass fuel combustion]
The emissions resulting from combustion of biomass fuels are
zero since they are carbon neutral.
[Emissions from fossil fuel combustion]
The emissions from combustion of fossil fuel at a biomass power
plant are calculated from the amount of fossil fuel consumption,a net calorific value of the fuel and a CO2 emission factor of thefuel.
[Emissions from transportation of solid biomass fuels]
The emissions from transportation of biomass residues arecalculated from the amount of fossil fuel consumption by thetransportation, a net calorific value of the fuel and a CO2emission factor of the fuel, if applicable. If not applicable, theemissions from transportation of solid biomass fuels arecalculated from total mass of freight transported from eachcollecting site, distance between each collecting site and abiomass power plant and a CO2 emission factor of thetransportation.

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

A biomass power plant is newly installed and supplies electricity to theregional grid and/or a recipient facility.

Criterion 2

The project power plant(s) uses only solid biomass fuels made of biomass
residues.

Criterion 3

Solid biomass fuels utilized for the project are not used for energy applicationsin absence of the project activity. This can be demonstrated by the letter fromsuppliers of biomass residues.

biomass power plant which replaces grid electricity and/or captive use where the project is
implemented during a given time period.
The default emission factor is set in a conservative manner for the Chilean regional grids: theNational Electricity System (SEN), the Aysén system and the Magallanes system. The emission
factor is calculated based on the conservative operating margin that reflects on the latest
electricity mix including low cost/must run resources for each regional grid in Chile during
2019-2021 and refers to the conservative emission factor of each fossil fuel power plant tosecure net emission reductions. The conservative emission factor of each plant is calculated tobe 0.826 tCO2/MWh for coal-fired power plant and 0.352 tCO2/MWh for gas-fired power plant
based on the survey on heat efficiency of power plant in Chile. The emission factor for diesel
power plant is calculated to be 0.533 tCO2/MWh based on a default heat efficiency of 49%, anefficiency level which is above the value of the world’s leading diesel power generators. As aresult, in case a biomass power plant in a proposed project activity is connected to the regionalgrid, the emission factors shown in section I of this methodology are applied. In case a biomass
power plant in a proposed project activity is connected to an internal grid which is notconnected to the regional grid, the emission factor is set to 0.533 tCO2/MWh.
The emission factors for each region are shown in Section I.
