says Zilmar de Souza, Bioelectricity Manag-
er at the Brazilian Sugarcane Industry Asso-
ciation (Unica).
The supply of bioelectricity to the electri-
cal grid has been rising year after year in the
the boilers, bagasse generates steam, which
drives the turbines for theproductionof elec-
tricity ina sustainablemanner.
Nowadays, the national power plants
generatemore than 21 TWh for the electrical
grid, representing 5 percent of the electricity
consumed inBrazil. “Over these 30 years, the

more appropriate environment for the
commercialization of energy. “The es-
tablishment of robust and regular new
projects focused on bioelectricity from
sugarcane, with appropriate prices in
the regulated auctions, is necessary if
the supply chain is to continue operat-

16.0TWh in2013, up32percent, according to
data furnished by Unica. Over the following
years, increases reached 21 percent in 2014
and 5 percent in 2015 and 2016. “The 21.2

The estimated value of the energy gen-
erated for the NIS by biomass amounts to
nearly 24 thousand GWh in 2016, up 5 per-
cent from the previous year. This energy was

of 10million tCO2, amount that corresponds
to the cultivation of 71 million native trees
over a20-year period.
