The transmission and distribution of electricity in Argentina is highly regulated by the state.
There are two main electricity systems in Argentina: SADI (Argentine Interconnection System), serving the northern and central areas of the country, and SIP (Interconnected Patagonian System), serving the southern cone of the country. The two systems have been integrated since 2006.
Almost 30 percent of the rural population in Argentina has no access to electrical services. There are several government-run programmes in place aimed at increasing electrical coverage in rural areas. It should be noted, however, that the deterioration in the services provided by distribution companies (i.e. cables, transformers, etc.) could jeopardise supply. Even so, the average frequency and duration of service interruptions is considerably lower in Argentina compared to the rest of Latin America and the Caribbean region.
Standard electricity supply is at a voltage of 220 Volts and a frequency of 50 Hz.
Type C plugs, with two round pins, were traditionally used in Argentina, and may still be seen on older appliances. Type I plugs, with two flat pins forming an inverted V and one vertical flat pin, are more commonly in use. There are also some special plugs available on the market for high-consumption appliances. The use of adapters is very frequent.
Note: An adapter allows the plug on the electrical appliance to be adapted to the plugs in Argentina, but care should be taken to ensure that the appliance accepts the corresponding voltage and has been configured for it (with a selector switch, for instance). Otherwise a transformer should be used.
For small home appliances (with the exception of hair dryers), a 50 watt transformer is sufficient, while larger appliances, or those generating heat (hair dryers, irons, etc.) require a 1600 watt transformer.
Some computers, televisions and VCRs work at an electrical frequency of 60 Hz, which means it is not advisable to connect them to lines having a frequency of 50 Hz, even using the right converter.
