Domestic Electricity in Portugal

The main electricity company is Energias de Portugal (EDP)

Portugal's standard electricity supply is 220 Volts (V), 50 Hertz (Hz) AC although in some older properties it may still be possible to find a 110 Volts supply or a combination of the two.

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

In some remote areas such as the Serra da Estrela and Trás-os-Montes there are still some isolated rural communities without mains electricity supply using generators.

Plugs and Adapters

Portugal uses the standard European two-pin plug and socket.

• See Wikipedia for an explanation and diagram

All domestic goods purchased in Portugal will have a compatible two-pin plug attached. For appliances with foreign plugs, adapters (Adaptador) can be bought or the plug can be changed. Adapters are available at most supermarkets, airports, some hotels, and electrical goods shops. DIY stores also stock them.

Appliances from the United States

It is not recommended to bring electrical appliances with a motor from the USA (appliances such as refrigerators, electric can openers, stereos). The voltage in the US is 110 and 60 hertz, while in Portugal it is 220 volts and 50 hertz. The appliances would need a transformer. 

If using a US-bought transformer, the following adaptor may be required: a Ficha Tripla Plana or Ficha Plana available at stores such as Continente.

Light Bulbs

The standard light bulb fitting in Portugal is a screw or Edison fitting.

Power Cuts

Portugal operates a power rating system (Potência Instalada) where a household or the electricity company calculates its average usage and the supply is based on this. This can mean that using a washing machine, microwave and toaster or kettle at the same time will cause the power to cut out in some older properties or households with a lower rating system.

It is worth knowing that during peak electricity usage periods and storms the electricity supply may be cut; this happens regularly in many regions. If your business or home depends on power it is worth considering installing a generator or UPS system for computers.

A power surge protector is also recommended to protect appliances (computers, TVs, fax machines) when the power supply is resumed.
