ECOnomics

The choice for willow as a renewable energy plant is determined by economic and ecological benefits of energy willow varieties growing. Those benefits together constitute the ECOnomics of energy willow growing which can be demonstrated in base figures of capital expenses and operational expenses of plantation establishing and maintenance, as well as in the end results of energy willow biomass yields, the costs of harvesting and the logistics related to the end use of energy willow chips or production and exporting of pellets.

Energy yields of willow vs other energy plants

The yield of biomass in energy equivalent figure harvested per hectare of energy plantation is the key parameter in local energy plant consideration.  Energy yields of various plants* Энергетическое растение Dry mass yield Energy production per hectare MT DM  per ha GJ per ha Willow 15-17 280-315 Poplar 9-16 170-300 Miscanthus 8-32 140-560 Straw 2-4 …

Heat generation comparative costs

The key financial figures that demonstrate economic feasibility of various heat sources are the direct costs of heat generation. Heat generation costs provided on the graph are based on the direct raw material (biomass or other) costs at the point of heat generation. Thus, infrastructure capital expenses such as gas pipelines, mines, electric grids, oil …
