Overview
Empresa Brasileira de Participações em Energia Nuclear e Binacional S.A. (ENBPar) is a Brazilian state-owned, closely held corporation controlled by the federal government through the Ministry of Mines and Energy. It was authorized by Law No. 14,182 of 2021 and formally created by Decree No. 10,791 of September 10, 2021, as part of the legal framework for the privatization of Eletrobras. ENBPar was designed to take over the activities and assets that could not be transferred to private investors, notably the Brazilian stake in Itaipu Binacional and the nuclear energy company Eletronuclear, as well as the management of certain public policies. ENBPar is the commercializing agent for Itaipu Binacional, the binational hydroelectric entity established by the 1973 Itaipu Treaty between Brazil and Paraguay. ENBPar holds 50% of Itaipu, with Paraguay's Administración Nacional de Electricidad (ANDE) holding the other 50%. In the nuclear sector, ENBPar holds 64.10% of the ordinary shares of Eletronuclear, which operates the Almirante Álvaro Alberto Nuclear Power Plant, comprising Angra 1, Angra 2 and the under-construction Angra 3. In October 2022, ENBPar's share capital was increased through the contribution of all shares held by the federal government in Indústrias Nucleares do Brasil (INB), giving ENBPar control of INB and ending its dependence on Treasury resources. Beyond its equity holdings, ENBPar is responsible for managing public policies in the electricity sector, including the Luz para Todos (Light for All) universalization program, Mais Luz para a Amazônia, contracts under the Proinfa renewable energy incentive program, and the Procel energy conservation program. It also manages assets of the federal government under Eletrobras administration (BUSA) and contracts of the Reserva Global de Reversão (RGR) fund signed before November 17, 2016. According to its official website, ENBPar describes itself as working to universalize energy supply, producing, commercializing and encouraging the use of renewable energy, with commitments to safety, innovation, socio-environmental responsibility and advanced governance practices. The company states that Itaipu Binacional, Eletronuclear and Proinfa plants generated 76,569 GWh in 2022, about 13% of all energy generated or injected into the National Interconnected System (SIN). It also reports that Procel actions saved 22,100 GWh in 2022, enough to supply the city of São Paulo for a year, and that the Luz para Todos program has benefited 17 million people, bringing electricity to more than 3.6 million rural and remote households with R$ 24.3 billion invested over 20 years. ENBPar is the third-largest power generation company in Brazil by installed capacity and the largest state-owned company in the sector, representing 5.1% of the country's installed capacity. It is headquartered in Brasília and operates as a public company under private law, with its shares not traded on stock exchanges.
History
ENBPar was created in the context of the privatization of Eletrobras, Brazil's largest electricity company. Law No. 14,182 of 2021 authorized its creation and set the terms for Eletrobras' privatization, while Decree No. 10,791 of September 10, 2021 formally established the company. The purpose was to transfer to a new state-owned entity the activities and assets that could not be privatized, including the Brazilian stake in Itaipu Binacional and the nuclear energy company Eletronuclear, as well as the management of public policies in the electricity sector. On June 14, 2022, 802.1 million Eletrobras shares were sold at a base price of R$ 42, in an operation that moved R$ 33.7 billion. As a result, the federal government's share of Eletrobras' voting capital was reduced from 68.6% to 40.3%. After the privatization, ENBPar injected R$ 3.5 billion into Eletronuclear, reducing Eletrobras' stake to 35.9% of Eletronuclear's voting capital. In October 2022, a general shareholders' meeting approved an increase in ENBPar's share capital through the contribution of all shares held by the federal government in Indústrias Nucleares do Brasil (INB). With this operation, ENBPar assumed controlling ownership of INB, ceasing to be a state-owned company dependent on National Treasury resources. In July 2022, the government of President Jair Bolsonaro announced it had sent a bill to Congress to enable the initial capitalization of ENBPar. The bill provided for a special credit of R$ 1.2 billion to the Ministry of Mines and Energy's fiscal budget. According to the government, the bill did not affect primary result targets because it involved reallocation among mandatory primary expenses, and it was compatible with the "Golden Rule" and the "New Fiscal Regime." ENBPar is responsible for managing assets of the federal government under Eletrobras administration (BUSA) and contracts of the Reserva Global de Reversão (RGR) fund signed before November 17, 2016, covering reversal, expropriation, expansion and improvement of public electricity services. It also oversees public policies including the Luz para Todos universalization program, Mais Luz para a Amazônia, contracts of the Proinfa renewable energy incentive program, and actions of the Procel energy conservation program. As of its establishment, ENBPar became the third-largest power generation company in Brazil by installed capacity and the largest state-owned company in the sector, representing 5.1% of the country's installed capacity. Its subsidiaries and holdings include Itaipu Binacional (50%), Eletronuclear (64.10% of ordinary shares) and Indústrias Nucleares do Brasil (controlling shareholder).
