Title: V.b Bioenergy imports costs

Content: Imported bioenergy is split into imported liquid fuels and imported solid fuels:

# Liquid fuels are modelled as diesel or petrol substitutes, but without being specific as to their actual form so they could be oil derived biodiesel, or they could be a Gasification+FT based petrol replacement.  See Biomass liquid fuel imports cost data for the current cost assumptions.
# Solid fuels are modelled as coal substitutes, but again without being specific as to their actual form, so they could be wood, dedicated biocrops, or straw. See Biomass solid fuel imports cost data for the current cost assumptions.

h1 TECHNICAL ASSUMPTIONS

Bioenergy imports are modelled on sheet V.b of the excel model.

The technical assumptions are documented on pages 163 to 166 of the original 2050 Pathways Analysis Report. The assumptions were not changed in the Government's response to the Call for Evidence. 

The calculator assumes that:

# The imported biomass is a direct substitute for coal, with no further processing required.
# The imported biofuel is a direct substitute for oil, with no further processing required.

The calculator also assumes a merit order, with priority given to:

# Domestic bioenergy, if available
# Imported bioenergy, if available
# Domestic fossil fuel produciton, if available
# Imported fossil fuels.

h1 COSTS METHODOLOGY

# The user defines the maximum amount of solid and liquid feedstocks of bioenergy that will be imported (in terms of the Gross Calorific Value of the fuel). 
# This energy content is multiplied by the cost of the import per unit of energy (e.g., £/TWh, or £/PJ)

The £/TWh working assumptions are:

* Solid biomass imports: 2050 working assumption Biomass solid fuel imports 2010-2050
* Liquid biofuel imports: 2050 working assumption Biomass liquid fuel imports 2010-2050

h1 QUESTIONS TO STAKEHOLDERS

Should a wider range of liquid and solid feedstock imports be considered in creating the import costs data range?
