Measures for contingency planning, management plan and training programs for disasters/emergencies

Norte Energia, the concessionaire of the Belo Monte Hydroelectric Power Complex—the largest Brazilian fully domestically-owned HPP—prioritizes the safety of its dams and associated structures. To this end, the Company has a robust Dam Safety Plan (PSB) in line with the National Dam Safety Policy (Law No. 12334/2010, updated by Law No. 14066/2020). 

The Belo Monte Hydroelectric Power Complex comprises six dams, 30 dikes, a diversion canal, two powerhouses and a spillway (flow capacity of up to 62,000 m³/s), subject to continuous and thorough monitoring to ensure the integrity of the structures. Norte Energia keeps the Dam Safety Plan (PSB) and the Emergency Response Plan (ERP) up to date, with specific guidelines for risk prevention and mitigation, including implementation and maintenance of evacuation routes, signage and notification system – essential elements for the safety of communities located in the Self-Rescue Zone. 

In 2024, a Regular Safety Inspection confirmed that the structures remain at a “Normal” safety level, in accordance with ANEEL Normative Resolution No. 1064/2023. The Company also completed a pilot project for partial instrument automation, modernizing 182 of them and integrating data into the Dam Safety Management System, therefore enabling real-time readings. 

In terms of sustainability, the use of self-propelled robots to cut vegetation increased the safety of the activity and reduced pollutant emissions. The Emergency Notification System has been modernized, with 42 high-performance sirens and new communication channels, including the Internet to expand connectivity in areas without cell phone coverage. 

Norte Energia also made improvements to evacuation routes (over 52 km), with recovery of access and improvements to the drainage system. More than 2,000 signposts were installed in 2024 to ensure functionality. Theoretical training and practical simulations were carried out within the scope of the ERP, with the participation of more than 600 people, reinforcing the culture of prevention with the support of state (CEDEC) and municipal (COMPDEC) Civil Defense forces.
