Biomass related questions #104

Thanks for your message on this. We use the medium housing, low wood energy scenario for the biomass supply curves. This is the scenario that the Billion Ton Study considers as a baseline. You are correct about the binning--the Billion Ton Study takes all the biomass supply and then aggregates it to those specific price levels for each bin. We don't have variation in biomass prices per year, although if the model uses more biomass in one year then it may face more expensive resource costs from those higher-priced bins. The only type of biomass we modeled is woody biomass; we exclude liquid fuels derived from crops or grasses. We have included some cost estimates for turning the woody biomass into pellets for combustion. By the way, the latest version of ReEDS utilizes the more recent Billion Tons Study Data (2016). See below for an updated plot of the supply curve, now with some breakdowns by region. |

Hi ReEDS Team, I have a few questions about the biomass supply curves in the model.
I was wondering about which scenario in the U.S. Billion Ton Update (DOE 2011) that was used to derive the biomass supply curve below?

"Biomass fuel prices are represented by a supply curve with five bins per region". Does this mean that the bins division are based on price differences? Do input biomass prices vary from year to year or static?
Which type of biomass is used in the model as a fuel input for dedicated biomass IGCC plants or coal-fired plants?
Thank you so much!
