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 region's installed capacity, with the remaining 42% corresponding basically 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 accounted for the rest. The South Region owns the Itaipu Dam, which was the largest hydroelectric plant in the world for several years, until the inauguration of Three Gorges Dam in China. It remains the second largest operating hydroelectric in the world. Brazil is the co-owner of the Itaipu Plant with Paraguay: the dam is located on the Paraná River, located on the border between countries. It has an installed generation capacity of 14 GW for 20 generating units of 700 MW each. North Region has large hydroelectric plants, such as Belo Monte Dam and Tucuruí Dam, which produce much of the national energy. Brazil's hydroelectric potential has not yet been fully exploited, so the country still has the capacity to build several renewable energy plants in its territory. according to ONS, total installed capacity of wind power was 22 GW, with average capacity factor of 58%. While the world average wind production capacity factors is 24.7%, there are areas in Northern Brazil, specially in Bahia State, where some wind farms record with average capacity factors over 60%; the average capacity factor in the Northeast Region is 45% in the coast and 49% in the interior. In 2019, wind energy represented 9% of the energy generated in the country. In 2019, it was estimated that the country had an estimated wind power generation potential of around 522 GW (this, only onshore), enough energy to meet three times the country's current demand. In 2021 Brazil was the 7th country in the world in terms of installed wind power (21 GW), and the 4th largest producer of wind energy in the world (72 TWh), behind only China, USA and Germany. Nuclear energy accounts for about 4% of Brazil's electricity. The nuclear power generation monopoly is owned by Eletronuclear (Eletrobrás Eletronuclear S/A), a wholly owned subsidiary of Eletrobrás. Nuclear energy is produced by two reactors at Angra. It is located at the Central Nuclear Almirante Álvaro Alberto (CNAAA) on the Praia de Itaorna in Angra dos Reis, Rio
