How do the new regulatory measures from January 1, affect electricity bills?

The Government published Royal Decree-Law 8/2023 of 27 December in the Spanish Official State Gazette (BOE), which applies a reduction of VAT on electricity from 21% to 10%.

How do these changes affect your electricity supply?

Taxes on your electricity bill:

From 1 January 2024, the following is envisaged:

  1. Value Added Tax (VAT) changes to 10% for contracted power equal to or less than 10 kW, provided that the average wholesale market price in the calendar month prior to the last day of the billing period is above €45/MWh*. This reduction is expected to last until 31 December 2024. The average price of electricity in February was €40/MWh* and therefore invoices for which the billing period ends on a day in March 2024 will be subject to 21% VAT.

    The VAT rate to be applied, whether reduced (10%) or general (21%), may change again in the course of 2024, depending on whether the price of electricity in the wholesale market remains above or below the threshold set by the government.

    Only in the case of consumers considered severely vulnerable and severely vulnerable at risk of social exclusion (supplied by a reference marketer and covered by the corresponding social bonus), the VAT of 2024 will always be 10%, regardless of the wholesale market price.

    *Megawatt hour: the energy consumed in households is measured in kilowatt hours (kWh) and on the electricity wholesale market in megawatt hours (MWh). You can see developments in market prices here.

  2. The general rate of the Special Tax on Electricity (IEE) is reduced to 2.5% (previously higher than 5%) during the first quarter. The IEE on invoices issued in the second quarter of 2024 will be 3.8%, and it will later return to the normal rate of 5.113%.

If I qualify for the Social Rate, how do these changes affect me?

Holders of electricity contracts who are beneficiaries of the Social Rate and have the status of severely vulnerable or severely vulnerable at risk of social exclusion as established in RD 897/2017, will be invoiced with VAT at 10% throughout 2024, regardless of the market prices.

For beneficiaries of the Social Rate who are considered vulnerable, as well as for beneficiaries of the Social Rate established for low-income working households, VAT will be applied depending on the average market price, as discussed previously.

VAT applicable during the year 2024
Hired electricity power Energy price
> €45/MWh
Energy price
≤ €45/MWh
Electricity power ≤ 10 kW VAT 10% VAT 21%
Electricity power > 10 kW VAT 21% VAT 21%
Severely Vulnerable and
Severely Vulnerable
at Risk of Social Exclusion
VAT 10% VAT 10%

The vast majority of Spanish households fall within this range (≤10kW).

To which items on the invoice does the 10% VAT reduction apply?

If your power is equal to or less than 10 kW and the established average market price criterion is met, the VAT that you will have to pay on bills issued in 2024 will be 10% on tariffs and charges, energy consumption and meter rental.

There are other items on the bill such as services, connection charges, grid connection charges, etc., to which the 21% VAT rate will always apply.

Why is the price of electricity increasing?

The price of electricity is increasing mainly for two reasons:

  • The rise in the price of gas.
  • The rise in the prices of CO2 emission rights.

For customers who are in the regulated market, the price of electricity is calculated in accordance with the PVPC (Voluntary Price to the Small Consumer) that is calculated according to the price registered by the market every day and every hour, so it is affected by variations in this market.

How long will the new VAT rate last?

The new VAT on electricity is expected to last until 31 December 2024, as long as market prices remain above €45/MWh and the contracted capacity is equal to or less than 10 kW.

In February 2024, prices fell below the established amount, so VAT has been increased from 10% to the original 21%. The VAT rate to be applied, whether reduced (10%) or general (21%), may change again in the course of 2024 depending on the price of electricity on the wholesale market.

Does it also affect other supplies such as gas?

VAT on gas, which was previously at 5%, also changes to 10%, but only until 31 March, 2024. Following this date, VAT on gas is expected to return to the normal rate of 21%.
