Changing your electrical power in Energía XXI

It is very easy to change your contracted power (kW) with Energía XXI. And being able to calculate the best level for you is just as important as being able to change it. We'll explain everything you need to know to make the best decision for your needs.

Choosing the contracted power in PVPC (Voluntary Price for Small Consumers)

In the regulated market or PVPC, you can contract two power levels: one for off-peak hours (each kW is cheaper) and one for peak hours (each kW is more expensive).

These two power levels can be the same or different. Your decision should be based on your consumption patterns and the times when you have most appliances running at the same time.

The bands for your contracted power are:

  • Off-peak period: 12 midnight to 8am from Monday to Friday (except public holidays), and 24 hours a day on Saturdays, Sundays and national public holidays.
  • Peak period: Monday to Friday (except public holidays) from 8am to 12 midnight.

Now you need to know how you can change your contracted power with Energía XXI, and how you can find out what you really need with our power calculator.

How to change your power levels with Energía XXI

Changing your contracted power is very quick through your Energía XXI Customer Area. Here is how to do it:

1. Log into your Customer Area

Just enter your username and password on the Customer Area page. If you haven't registered yet, here is how to register with Energía XXI.

2. Go to the "My Contracts" section

In the top menu, click "My contracts" to display the electricity contract for which you can change the contracted power levels.

3. Make your changes to the "Power and voltage" section

The "Power and voltage" section displays the power you have currently contracted, with an option to change this through the "Change" link.

4. New peak and off-peak power levels

Clicking the "Change" link opens a pop-up window where you can select the new power levels, both peak and off-peak. Once you have entered your changes, click the "Save changes" button.

5. Review the values before saving the changes

Choosing the right power for your electricity supply isn't always easy but it is important to get it right. Too low and you will be "blowing a fuse" all the time, too high and you will be overpaying on your bill.

That's why it's important to check the values before saving your changes. If you need some advice, we recommend using our Energía XXI power calculator, which you can find in the same window.

We explain how to use the calculator in the next point in this article.
