- Empresa Metropolitana de Águas e Energia S.A. Empresa Metropolitana de Águas e Energia S.A. engages in the planning, construction, operation, and maintenance of hydroelectric power generation systems, hydraulic infrastructure, and related energy commercialization activities in Brazil. The company operates a complex hydraulic system including dikes, dams, reservoirs, and spillways such as Billings and Guarapiranga in southern São Paulo; pumping stations at São Paulo and Pedreira; the Pinheiros River channel; and five hydroelectric plants—Henry Borden (889 MW), Porto Goes, Rasgao, Izabel, and Edgard de Souza—forming the Alto Tietê power complex, with total installed capacity of approximately 960.8 MW, alongside flood control operations, ferry services at Billings Reservoir, asset construction, and operation and maintenance services for industrial facilities and public entities. Founded in 1899 and headquartered in São Paulo, the company serves the Metropolitana de São Paulo region, Baixada Santista, and Médio Tietê areas, targeting electricity utilities, private firms, and government bodies with renewable energy output of around 1.7 TWh annually. In 2024, Empresa Metropolitana de Águas e Energia S.A. underwent privatization as the State of São Paulo auctioned its majority stake to investment fund Phoenix FIP for BRL 1.04 billion (US$200 million), marking a shift from state control; additionally, in October 2025, Companhia de Saneamento Básico do Estado de São Paulo (Sabesp) announced the acquisition of a 70.1% controlling stake for BRL 1.13 billion (US$212 million) across share classes from Phoenix and Eletrobras to integrate water and energy operations. The company advances sustainability through initiatives like Brazil's largest floating photovoltaic plant and maintains 290 employees under CEO Marcio Reá.
