These charges are used, for example, to pay for energy production in non-peninsular territories, for waste treatment, for the deficit accumulated by the electricity system, etc.

9. Breakdown of the Energía XXI bill

Here you can find information about each of the amounts on the Energía XXI bill.

Billing by contracted power in euros

Also called a fixed term, and indicates the total price and each of the costs that it comprises.

  • Amount for transport and distribution fees: It is applied in both the peak and off-peak periods and is calculated by multiplying the contracted power (kW) by the regulated price for that power (A/kW) and by the number of days of the year of the bill period.
  • Fixed sales margin: this is a fixed and regulated cost related to the sale of power.

Billing by energy consumed

Also known as a variable term, it is the part of the Energía XXI electricity bill that has to do with the amount of electricity you consumed in the invoice period. As in the previous case, you will see two different amounts on the bill:

  • Amount for transport and distribution fees: regulated costs.  They are applied in three periods throughout the day (peak, standard and off-peak). The value is obtained by multiplying the value of the fee (A/kWh) by the consumption made during that period (kWh).
  • Energy cost: cost in euros for the energy consumption during the period comprising this bill, or what is the same, the price for the amount of electricity consumed with Energía XXI.

Electricity tax

This is an excise tax imposed on electricity: It is calculated by adding 5.11269632% of the energy cost of that bill.

Meter rental

If you do not have a meter on the property, the electricity bill also reflects the cost of its rental.

Application tax

These are what as known as indirect taxes. Reduced (10%) or general (21%) VAT in Peninsula and Balearic Islands, IGIC in the Canary Islands (0% consumption for homes with a power less than or equal to 10kW, rest 3%) IPSI in Ceuta and Melilla (1%).

Total amount of the bill

The sum of all sections results in the total amount of the electricity bill sent to you by Energía XXI.

10. Consumer information

Information about the type of contract and about the different discounts or surcharges. For example, the application of the Social Bonus or, on the contrary, surcharges for not being entitled to the PVPC.

This section of your Energía XXI bill contains a link and QR code to access the CNMC’s energy offerings comparison tool.

Regulated market electricity bill with Social Bonus

If you have been assigned the Social Bonus, your Energía XXI electricity bill will show that you are a beneficiary and the percentage of discount to which you are entitled.

Summary of the bill with social bonus in the regulated market

The information in this section is the same as for the standard PVPC bill, but with the difference that the social bonus discount is included.

Information about the contract with social bonus with Energía XXI

Similarly, in the contract information and the contract type section, you will see PVPC with Social Bonus and the discount % applied.

Breakdown of the bill for beneficiaries of the social bonus

On the back of the bill, where all the expenses are broken down, you will see the calculation of the social bonus discount applied in the billing period.

Information about electricity consumption with social bonus

If you are a social bonus customer, you will also see the consumption with and without the discount in theelectricity consumption information section of your Energía XXI bill.

Regulated market electricity bill for self-consumption

Some customers also have solar panels for self-consumption and whose surplus energy is introduced into the general electricity grid. In this case, they receive compensation for that surplus energy which is reflected in their regulated market electricity bill.

The compensation for surpluses (euros to be returned) is shown in both the bill summary and in the breakdown on the back.

In addition, the section with information about your electricity consumption indicates the offset surplus energy.

PVPC Energía XXI bills with surcharge

This is a very particular case but it should be clarified. If you do not qualify for the PVPC, but you don't currently have a contract in the free market, a surcharge will be applied to your Energía XXI electricity bill.

This 20% surcharge is reflected in both the bill summary and the breakdown on the back.

It will also be clarified at all times that the type of contract being applied to you is the Small Consumer Voluntary Price contract (PVPC) with a surcharge of 20%.

Billing for excess power in Energía XXI

Most homes and businesses attached to the regulated market cannot use more power than they have contracted. If, at any point, you have more electrical appliances than the maximum contracted power allows, the power control switch (formerly known as the "trip switch") will trip and you will not have any electricity until you flip it back again.

However, some people have a maximeter (this is an unusual situation with domestic customers). In this case, you could exceed the maximum contracted power, at a certain time, without the switch tripping, but assuming an additional cost.

In this situation you will see that cost for excess power in both the summary of your Energía XXI electricity bill and in the billing for excess power.
