Brazil ONS mounts special operation to secure power supply for 2026 elections

Brazil's grid operator ONS will run a special operation during the 2026 general elections, reinforcing standby teams, restricting maintenance, and monitoring weather to ensure supply security, per a 2005 CMSE resolution. This is a routine precautionary measure for a major national event, not a response to an active crisis. It signals elevated attention to grid reliability but no immediate market impact.
