This chapter presents and discusses the potential of power generation from last sugarcane harvest (2016/2017), mainly by the combustion of two by-products; bagasse and straw. Bioelectricity production from the bagasse and the straw is possible through the grinding sugarcane, and both are available in the driest period of the year (May to September) and match with the water shortage in the reservoirs of hydroelectric power plants to the same period. Brazil is the largest producer of sugarcane of the world, in 2016/2017 reaped 657,189.900 tons, this crop is concentrated in four states that are responsible for over 90% of the bioelectricity production. Considering 2016/2017 harvest, we have foreseen that the availability of bioelectricity could reach 74,994 GWh, but if we aggregate straw to the combustion at the boiler, the electricity produced would reach 111,558 GWh. This power energy produced is almost 20% of total power energy supply in 2016, when power generation was 570,562 GWh. This way, Brazil could increase the share of the renewable resources at its power energy matrix and avoid greenhouse gas emission. Moreover, we present a deep discussion about the current federal regulatory scope of Brazilian electricity market and how bioelectricity fits into this competitive market.
