A Cemig outage hit about 26,900 customers in Belo Horizonte after a storm on the afternoon of Thursday 5 November 2026, the power company said. About 1,600 customers were still without electricity on Friday morning, and crews expected gradual recovery through the day.
Cemig, the Minas Gerais electricity company, pointed to fallen trees and objects thrown against its lines. It asked customers still in the dark to report the outage by phone or app.
What Happened in Belo Horizonte
Intense rain struck Belo Horizonte, the capital of Minas Gerais state, on Thursday afternoon. Cemig said the outages hit the Noroeste, Leste and Pampulha regions of the city most heavily.
The company counted about 26,900 customer units without power, which it put at 2.7% of its customers. A customer unit is a single connection to the grid, such as a home or a shop.

Why the Power Went Out
Cemig said the storm brought down trees and threw objects and vegetation against the electrical network. That may have caused short circuits, cable breaks and other damage to the distribution lines.
Distribution lines are the local wires that carry electricity from substations to homes. Damage to them can leave whole streets dark even when the main grid is intact.
How Fast Power Is Coming Back
Cemig said its crews were mobilised and working without a break. On Thursday evening it expected power to return gradually through the night, with complex repairs possibly running into early Friday.
By Friday morning, about 1,600 customers in Belo Horizonte were still without power. Cemig said it expected the supply to return to normal gradually during the day.
How to Report an Outage
Cemig asks customers who lose power to report it by calling 116 or using its Cemig Atende app. The company says each report lets it send a crew to check the local line.
Customers can also report a power cut on the Cemig website through its Cemig Atende Web service. After logging in, they choose the option “Estou sem luz”, meaning “I am without power”.
In Plain English, Who Is Who
Cemig is short for Companhia Energética de Minas Gerais, the electricity company that serves Belo Horizonte. Belo Horizonte is the capital of Minas Gerais, a large state in south-eastern Brazil.

What It Means for You
For US investors in Brazilian utilities, one storm is a small event, but repeated outages can bring complaints and regulatory scrutiny. Cemig is a major electricity company in a large Brazilian state.
Travellers in Belo Horizonte can report a power cut by phone or app, as Cemig asks. Anyone still without power on Friday should use those channels so a crew can check the line.
What Is Not Known
The cost of the damage has not been reported. Cemig can say how many poles and cables were replaced when it publishes its next update.
It is not known exactly when the last customers will be reconnected. Cemig can say when it confirms that supply has returned to normal.
