SPECIALISTS IN O&M OF ELECTRICAL ASSETS
COTESA Engenharia specialises in the Operation & Maintenance (O&M) of power generation and transmission assets. Founded in 1997, the company invests continuously in technology, innovation and technical knowledge, and was one of the first in Brazil to perform live-line maintenance, a high-complexity procedure carried out on energised systems.
We work on high and extra-high voltage assets connected to Brazil’s Basic Grid: transmission lines and substations up to 600 kV, hydroelectric plants, photovoltaic solar farms, wind farms, and the medium and high voltage systems of energy-intensive industrial plants.
