In 2013, the Southeast used about 50% of the load of the National Integrated System (SIN), being the main energy consuming region in the country. The region's installed electricity generation capacity totaled almost 42,500 MW, which represented about a third of Brazil's generation capacity. The hydroelectric generation represented 58% of the installed capacity in the region, with the remaining 42% basically corresponding to the thermoelectric generation. São Paulo accounted for 40% of this capacity; Minas Gerais by about 25%; Rio de Janeiro by 13.3%; and Espírito Santo for the rest. Among the renewable sources for thermoelectric generation, sugar cane biomass stands out, with more than 6,300 MW of capacity, distributed in more than 230 plants. Among the non-renewable sources, natural gas, with almost 6,300 MW, thermonuclear generation, with 2,000 MW, and oil products, with 1,100 MW.
