How can you save money on your electricity bill in Uruguay?

We all know how expensive electricity is in Uruguay but did you know...you can go to any UTE office and change your electricity meter to a split tarrif which means you pay around 2.375 per kWh during off peak (i.e during the day) and 6.244 per kWh during peak hours (5-11pm in winter and 6-12pm in summer).  This can save you money if you are home during the day and/or use most of your power then.  Also you can set timers on hot water tanks, washing machines, dishwashers to operate after the peak ends at 11pm or midnight.  The normal rates for electricity (not on split tarrif) are: 3.476 for 1-100kWh, 4.700 for 101-600kWh and 5.390 for
601kWh onwards. So it doesn't take long before you are paying 5.390 for a lot of your power whereas on split tarrif you would only be paying 2.375 for most hours and overall may end up paying a lot less.
