Electricity and Home Appliances in Brazil

Find out how to get connected to Brazilian electricity suppliers...

Brazil’s electricity supply is run on a state basis, with the majority of towns being provided by each state’s own individual, privately-run company.

Brazil’s energy sector is regulated by ANEEL, a Brasília-based federal government watchdog.

Main Electricity Providers

One of the country’s most important energy generation and distribution companies is CEMIG, which serves the state of Minas Gerais. Although privatized, the state government controls just over 50 percent of the company’s stock.

The company serving the majority of Rio de Janeiro state is called AMPLA. There are a few smaller energy companies in certain parts of the state capital, as well as in some of the upstate towns.

São Paulo state is served by four companies, created when Eletropaulo was privatized in 1999. The company serving the São Paulo metropolitan region is called AES Eletropaulo, which is the largest electricity distributor in Latin America.

Other regional electricity suppliers in Brazil include:


Depending upon the state, the voltage employed for electrical goods is either 110v or 220v, with a frequency of 60 hertz.

Most states use 110v, although certain towns may employ the 220v system. The capital of Rio de Janeiro state for example uses 110v, but some of the neighboring cities use 220v.

Exceptions include some states in the north and, notably, the capital city of São Paulo, which use 220V.

Most electrical appliances are sold with a conversion switch, so when traveling between regions it is always advisable to check the local voltage before plugging in. Usually there will be a small sticker on the plug displaying the number of volts required.

  • The Ecoviagem: Easy and Interactive Tourism website has a list of Brazilian cities and the voltage used in that area.
  • Electricity can be unstable in some parts of Brazil and electricity surges are common. Electronic equipment can be protected by installing a voltage regulator.


Brazil uses both two and three-pin plugs. There can be a combination of socket types within the same room or property. Low voltage appliances generally use two-pin plugs, with higher voltage appliances (televisions and washing machines) using the three pin plug which has an earthed (or grounding) third pin.

Both two-pin and three-pin plugs can differ between a round or flat pin, and although any sort of adaptor can be purchased in electrical goods stores, it is advisable to change the plug to fit the socket.

Light Bulbs

The standard light bulb fitting in Brazil is a screw fitting.

Note: A country's available voltage is printed on the glass of the bulb, or the light bulb packet.
