Dam safety in the FURNAS System
Hydropower plants play a strategic role in the country's development: they produce clean and renewable energy, control river floods, supply communities and create jobs. The dams are large structures of which are constantly monitored and inspected to ensure complete operational safety.
The standards set by the National Policy on Dam Safety (Law No. 12.334/2010) and regulations issued by the National Electric Energy Agency (Aneel) in Resolution 696/2015 are fundamental to the properly control and maintain dams.
For over 40 years, FURNAS has been enforcing its dam safety control protocol, which includes regular inspections and corrective and preventive maintenance for all its many generating facilities.
Plants in the FURNAS System all have a team of operators and managers who have been trained to verify structural conditions on site and the data recorded by local monitoring equipment. This means on-site engineers can make more efficiency decisions.
Equipment integrity and structural safety at each plant is implemented via various operational protocols, preventively tracking down any potential errors and issuing warnings so operators are able to intervene immediately or call in the relevant maintenance team.
Dam Safety procedures include periodic inspections by the FURNAS technical staff, supported by structural behavior assessments. These procedures are documented in Technical Inspection Reports (RITs) and the Behavior Study Reports (RECs), which are carried out as frequently as required at each unit.
These studies allow us to confirm that the dams are in full operating condition and do not present any abnormalities that might compromise their integrity and/or functionality. The reports are archived at each plant and made available to regulators.
The Dam Safety Plans for Plants that are part of the FURNAS System have already been delivered to appropriate bodies within the deadlines established by law. This information will help support initiatives by government agencies, as well as city halls, police, firefighters and Civil Defense. They are responsible for creating a Contingency Plan for each region and situation.
Dam Safety Engineering is a dynamic process of ongoing improvement, merging the efforts of qualified staff from the various companies and organizations involved to adopt the highest quality control and maintenance standards and ally efficiency with safety.
