The logic behind choosing your power is simple: you have to calculate the maximum kW that you are going to require from your network at the same time. You need to anticipate what may happen and think about those situations where you are going to have to push your electrical appliances to the limit. Under which circumstances do you turn on a greater number of them at once?
There are some things you can do without and others that you cannot do without. For example: maybe you can wait to put the washing machine on, leave it until everything is calmer. Maybe not. For example: maybe you are too hot in summer and need to turn on three air-conditioning machines and use the cooker at the same time.
The aim is to find the highest number of kW you are going to demand from your electrical installation. When you know that, you know how much power to contract. And always remember: if you overdo it, "you will blow a fuse".
How will you know if you have more power than you need?
To know if you have much more power than you really need there is an easy trick that usually works. Turn on all the electrical appliances in your house. Don't forget each of the air-conditioning machines, the oven and the hob if they are electric, even the vacuum cleaner. If you turn them on one after the other and the Power Control Switch (PCS) does not cut off, you probably have more power than you need.
If this is the case, your electricity bills are unnecessarily high. You are paying for something you never or almost never use, an excess of kW that is reflected every month in what you pay. It is in your interests to reduce the power contracted, but do not rush and think carefully before you do it.
Take advantage to also reduce your consumption
Power is one of the two major items on your bill. The other is consumption, which can vary considerably from month to month depending on the life you lead. Here in Endesa we put the best tariffs at your disposal.
If the power you have (or is suitable for you) is equal to or less than 10 kW, we recommend Tempo Happy, a tariff that enables you to choose 2 hours a day, 1 day a week or the 50 hours of highest consumption and during the chosen period to pay zero euros for your electricity consumption.
If the power you have (or is suitable for you) is greater than 10 kW, go to our specialised catalogue.
Don't decide without thinking carefully about it first
Power is the fixed item on your bill, something you are going to pay every month. For precisely this reason, increasing or decreasing it is not a decision to be taken lightly.
Unexpected expenses can come from several sources, including the electrical bulletin or Electrical Installation Certificate (CIE in Spanish). Whenever you modify the power, your distributor may inform you that new need a new bulletin which will cost between 100 and 150 euros approximately.
If you need to increase the power, to these expenses you would have to add about 45 euros for each kW you decide to increase it. If you decrease it, you will get approximately 11 euros no matter how much you decrease it. In addition to all this, your distributor could charge you for other procedures or require a deposit and make it difficult for you if you have already made any other power change during the same year.
For all these reasons, do not be hasty when reducing the power in search of savings. It is absolutely true: the less power you have, the less you will pay. And this item is also one of those that will be most significant in your bill. But it is also absolutely true that if you do not have enough power you will be forced to increase it again. And that process can get complicated and end up being expensive.
