It's winter in Argentina now, so they don't have AC loads. TVs are small by comparison (Although it's fascinating to see how load changes during large games: you can spot commercials, for example!)
>There is a common misconception that the number one driver of TV pickup is the boiling of kettles. In fact, this only creates a pull on the local network for a short period of time until the water has boiled, and can therefore be managed relatively easily, whereas flushing the toilet causes a longer surge at the water and sewerage pumping stations, and opening the refrigerator lets the chilled air escape, causing the compressor to run. These loads are more of a problem for the grid.
Basically a commercial break comes on, everyone turns on their tea kettle and flushes their toilets, and bam: 200-400 MW spike in demand.
There's some blogs out there charting this during big world cup games.
