History
Electrical power infrastructure in Rio de Janeiro was originally developed in 1904 by the Rio de Janeiro Tramway, Light and Power Company, a company financed with foreign capital and legally domiciled in Toronto, Ontario, Canada. After 1912, this company was part of the holding company Brazilian Traction, Light and Power Company (usually known in Brazil simply as "Light"), which eventually changed its name to Brascan (for "Brasil" + "Canada"). In 1979, the company's Brazilian assets transferred to Brazilian ownership. The Canadian company, which had in the meantime diversified to other areas, still exists under the name Brookfield Asset Management.

On May 12, 2023, Light filed for bankruptcy.
