How does communication take place between
Operations Center and ONS

The communication of an Operations Center with agents of the National Electric System Operator (ONS) and with the assets themselves is carried out through terrestrial and satellite links, always being recorded through voice recording systems.

In order to guarantee the fidelity of the messages and preserve the security of the electrical system, the real-time team interacts with the ONS and other companies that share the same System, through a standard language that must comply with the ONS Operation Procedures Manual.

Communication systems must have high availability, meeting the minimum criterion of 99.98%, that is, in an entire year the communication system cannot fail for more than 105 minutes. For this, the entire system must have redundancies that guarantee such performance.
