2 BT16 Sensitivity scenarios

Today’s presentation

• Why are energy crops important to the bioeconomy?• What are price and land impacts of energy crop

scenarios to traditional crops?

• What is sensitivity of energy crops to alternate assumptions of yield and land elegibility?

3 BT16 Sensitivity scenarios

Why energy crops?• Energy crops fill supply gap to a

billion ton annual supply• Competitive across crop and

pastureland, even in Corn Belt

• Measured market impacts

4 BT16 Sensitivity scenarios

Relation of BT16 results to historical and future commodity prices• Baseline scenario as

reference without shocks• Corn futures March 1,

2017= $3.72/bu,– 1-year range: $3.25-4.50/bu– 3-year range $3.10-7.20/bu

• BT16 results– Baseline, 2016: $3.50, 2040:

$3.77– Basecase, 2040: $4.03– Crossprice elasticities of

biomass to commodity crops all <1

5 BT16 Sensitivity scenarios

Land allocation of energy crops, base case

• Differential response of across energy crops to $60

• Energy crops competitive across ag land

• Switchgrass represents largest pastureland holder, miscanthuscropland holder

• Represents only 8.3% of pastureland and cropland

6 BT16 Sensitivity scenarios

Stakeholder feedback received in BT16 rollout

• Miscanthus yield growth and supply too optimistic– Miscanthus x giganteus (MxG) sterile triploid– Future improvements will require new varieties

• Sorghum supply too pessimistic– New varieties already exist– “Plug-and-play” annual crop

• Mix of feedstocks in BT16 can change with R&D improvements

7 BT16 Sensitivity scenarios

BT16 Agricultural Results, 2040

All crops increase in supply from base to high yield;MxG benefits disproportionately relative to other energy

crops from yield growth assumptions

14 BT16 Sensitivity scenarios

Conclusions

• Market effects of energy crops are measured in BT16 and fall within recent historical variability

• Land allocation of energy crops is diverse

• Small changes in feedstock growth parameters and land eligibility result in significant changes in feedstock mix

• BT16 scenarios capture reference case, but may not be “one size fits all” resource assessment
