Biomass Cordwood Component¶
-
class
aaem.components.biomass_wood.component.BiomassCordwood(community_data, forecast, diag=None, prerequisites={})[source]¶ Bases:
aaem.components.biomass_base.component.BiomassBaseBiomass Cordwood component of the Alaska Affordable Energy Model: This module estimates the potential reduction in heating fuel use from installation cordwood boilers in non-residential buildings. Reduction in fuel used is based on estimated output of hypothetical boilers. Savings result from difference in fuel prices between diesel and cordwood. The costs of the biomass projects are estimated from number of installed boilers and their size. Fuel use from improvements to heat recovery systems is based on existing projects. Reduction of heating fuel used results from improved recovery of heat during electrical generation.
Parameters: community_data : CommunityData
CommunityData Object for a community
forecast : Forecast
forecast for a community
diagnostics : diagnostics, optional
diagnostics for tracking error/warning messages
prerequisites : dictionary of components, optional
‘Non-residential Energy Efficiency’ component is a required prerequisite for this component

Parameters: scalers: dictionary of valid scalers, optional
Scalers to adjust normal run variables. See note on accepted scalers
Notes
Accepted scalers: capital costs.
Attributes
run (bool) True in the component runs to completion, False otherwise reason (string) lists reason for failure if run == False
