Your electricity bill will change from Tuesday, June 1, 2021, when a new model will come into effect.
From this Tuesday, you will pay a different price of energy depending on the time of use.
There will be a more expensive price (tip), a medium (plain) and a cheap one (valley). So, if you are able, you should try to concentrate consumption on the cheaper hours if you want to save money. For example by putting the dishwasher or washing machine on at night or weekends.
Below, is a diagram to show you the schedules of different periods.
