AM0007 Analysis of the least-cost fuel option for
seasonally-operating biomass cogeneration plants
Typical project(s) Refurbishment and fuel switch of renewable biomass cogeneration projects connected
to the grid which operate in seasonal mode and use other fuel during the off-season,
when biomass – for instance bagasse in case of a sugar mill – is not being produced.
Type of GHG emissions
mitigation action
Important conditions under
which the methodology is
applicable
• Renewable Energy.
Displacement of more-GHG-intensive power generation using fossil fuel.
• The proposed project has access to biomass that is not currently used for
energy purposes.
Important parameters At validation:
• Leakage emissions due to biomass transport and crowding out of biomass for
other plants;
• Baseline emission factor of the cogeneration plant based on the use of the
least-cost fuel available (usually fossil fuel).
BASELINE SCENARIO
Power would be produced
with the least cost fuel
(usually fossil fuels) in the
absence of the project.
PROJECT SCENARIO
Use of renewable biomass for
power generation avoids the use
of fossil fuel.
Monitored:
• Power generated by the project;
• Quantity of biomass used in the project;
• Electricity and fossil fuel consumption of the project.
