Companhia Energética Integrada (CEI), with headquarters in Belo Horizonte/Minas Gerais, was founded in 2004, with the objective of investing in the segment of electric energy generation through the exploitation of renewable sources. In 2006, the Company purchased its first generation asset, CGH Caquende, installed on Rio Macaúbas, a river in the municipality of Bonfim/MG. Between 2006 and 2012, confirming its vocation for purchasing mature assets, CEI started operating 8 other hydropower plants, both CGH (Central Geradora Hidrelétrica – micro hydropower plant – producing up to 1 MW) and PCH (Pequena Central Hidrelétrica – small hydropower plant – producing from 1 to 30 MW), located in the regions of Rio Casca/MG and south of the state of Minas Gerais. Subsequently, in 2015, CEI, consolidating its position in the electric energy generation market, entered into one of the largest operations in the electric energy industry in Minas Gerais, purchasing 06 PCHs in the Rio Doce basin, in the region of Ouro Preto/MG and Mariana/MG.
Currently, CEI operates 16 hydropower plants in the state of Minas Gerais, with a total of 42.82MW of installed power. All of the plants are fully automated and remotely operated by BEI – Brasil Energia Inteligente, a company from CEI´s economic group, specialized in providing O&M services for hydropower plants. Working in accordance with the highest ethical standards and focused on sustainability and respect for the environment, CEI, in addition to generating electric energy, develops greenfield projects in the segments of photovoltaic and hydropower generation. In its quest to open up new frontiers in the Brazilian electric energy sector, CEI founded ATMO Comercializadora de Energia Elétrica, a company strategically located in São Paulo, in order to handle the sales of electric energy and provide consultancy and advisory services in this field.
