The Gai Lai province has the highest calculated energy potential from all the prov‐
inces (in total, almost 4 TWh per year). Its potential of sugarcane residues represents one‐
seventh of the country’s full energy potential. It is also higher than the total potential of
several entire regions (Northern midlands and Mountain areas, Mekong River Delta, Red
River Delta) (see Tables 8 and 9). This potential corresponds to the energy consumption
of over 860,000 households.
Moreover, as discussed above, to use biomass as biofuel more efficiently, pretreat‐
ment is important. Especially in the case of sugarcane residuals, drying and moisture re‐
duction are essential for increasing the calorific value and thus obtaining higher energy
yield. Using the example of the sugarcane bagasse, Figure 4 displays the significance of
the difference between the energy potential of moist biomass (moisture content over 32%)
and dry basis biomass, i.e., 15.55 TWh per year vs. 24.63 TWh per year for Vietnam, re‐
spectively.
