• The price for bagasse was estimated to be $25/ton, as received.
• There is not a well established market from which to derive the cost of cane
trash. The price of $25/dry ton for bagasse is used as a proxy because similar
collection costs are expected.
• A range of prices is used for banagrass including $70, $80 and $90/dry ton.
This reflects various hauling distances and crop productivity in different areas.
Black & Veatch has derived these costs through recent studies of this fuel
resource. Because of the large supply potential of banagrass, this cost range is
considered to act as cap for the cost of biomass fuel. Alternately, the price of
coal could be used as a cap because a biomass plant would be well-suited to
burn coal.
A supply curve for the four previously mentioned fuels is shown in Figure 7-1.
