We believe that our work only makes sense if it generates value for society.

Therefore, we also operate in the energy segment.

About 54% of the energy consumption of our operations is supplied by our own generation, with emphasis on hydroelectric and wind sources.

Also as a result of the partnership with Cemig, Aliança Norte owns 9% of the Belo Monte Hydroelectric Power Plant. The plant is located in the state of Pará, and comprises the Pimental (233 MW) and Belo Monte (11,000 MW) sites. It is the largest 100% Brazilian hydroelectric power plant, and the 4th largest in the world.

For us, life always matters most.  

Therefore, the dams of our hydroelectric power plants undergo regular inspections and safety assessments, in accordance with the legislation. The activities are verified by specialized consultants and the results are registered with the competent authorities.

In Brazil, all of our dams have Dam Safety Plans (PSB) and Emergency Action Plans (PAE) filed with the respective city halls.

We have five hydroelectric power plants (PCHs) in Canada that are responsible for generating approximately 20% of the electricity demand of our Sudbury operations. 

Following our standard of inspections and safety assessments, in the province of Ontario, our dams are operated and maintained in accordance with best practices outlined in the Ontario Ministry of Natural Resources' (MNR) Lakes and River Improvement Act, and by the Water Management Plan of the Espanhol and Vermillion rivers, where the hydroelectric power plants are located.

Our daily work, built with you, is based on a fundamental pillar: respecting and caring for our planet. In Indonesia, we produce nickel, which includes the operation of three hydroelectric plants in the country: Larona, Balambano and Karebbe.

In Indonesia, all of our dams have received a Dam Safety Certificate by the Dam Safety Commission, as requested by the country's Ministry of Public Works.

Our biggest consumption is in electricity, especially in Brazil, Indonesia, Canada and , and in diesel. Do you know why? They are used primarily as fuel in off-highway trucks, which are fundamental to our operations, and in our railroad locomotives.

Energy efficiency

We have an Energy Efficiency Program in our operations with the objective of multiplying good energy consumption management practices throughout the company. 

Being energy efficient is essential to taking care of our planet and achieving our sustainability goals. In the program, we create the necessary conditions to seek improvements in energy performance through: 
  • Standardization of energy management processes;

  • Transparency in performance management;

  • Multidisciplinary teams for the implementation and management of the Program;

  • Use of automated energy measurement and management system.

Transmission and distribution 

In our operations in Brazil, we have our own lines and substations. In addition, we maintain collaboration with the concessionaires to which we are connected.
