ONS will carry out preventive operation to guarantee energy during the elections

The National Electric System Operator (ONS) will adopt preventive monitoring from 0h this Saturday (3) until 7h on Monday (5) to ensure there are no interruptions in the electricity supply during the First Round of the 2026 Elections, scheduled for next Sunday (4). The operation will be repeated in the second round, on October 25, starting on the 24th and ending on the 26th. >> Follow the 2026 Elections coverage on Agência Brasil Among the measures is a request that electricity distributors keep operation and maintenance teams on standby for emergency cases. The ONS also asks that scheduled maintenance involving load cuts or the risk of load cuts be avoided and recommends operating the electric system with reduced flows, in order to increase safety. The ONS director-general, Marcio Rea, said the measures seek to provide additional protection to the grid at a moment of great relevance for the country. "This preventive action seeks to preserve the reliability of the National Interconnected System and ensure that the energy supply occurs with stability and safety throughout the entire voting process." The operational plan also involves the exchange of information by the ONS on the system's performance and any occurrences with power generators, transmitters, and distributors, as well as with the Ministry of Mines and Energy, the National Electric Energy Agency (Aneel), the Superior Electoral Court (TSE), and the Regional Electoral Courts (TREs). On Monday (5), the ONS is expected to issue a report summarizing the technical information on the performance of the electric system's operating grid, highlighting the relevant facts that occurred during the operation. The initiative complies with Resolution No. 001/2005 of the Electric Sector Monitoring Committee (CMSE), which establishes that the ONS must propose additional security measures in order to guarantee the electricity supply during events of great relevance.
