Endesa offers all the advantages


Prices Tarifa One Luz

Prices for power equal to or less than 15 kW

*Prices excluding taxes. For electricity, the electricity tax will be added (0.5% or a minimum of €0.5/MWh or €1/MWh, as applicable) and for gas, the hydrocarbon tax (€0.00234/kWh). VAT (21% or 5% as applicable) or IGIC (Canary Islands 0%, 3% or 7% as applicable) will be added. The regulated cost associated with the financing mechanism of the social rate will be added to the prices: Fixed cost per customer (commercialization) of 0.03671762 €/day (Peninsula and Balearic Islands: 0.03874627 €/day taxes included for powers lower than 10kW and, for the rest of cases, 0.04465046 €/day taxes included; Canary Islands: 0.03690121 €/day taxes included for powers lower than 10kW and domestic customer and, for the rest of cases, 0.03800824 €/day taxes included). For supply points on the mainland, the regulated cost for financing the cap on the price of gas for electricity generation will also be added as part of the additional regulated cost involved in financing the measure. This regulated cost will appear in the invoice as “Cost for cap on gas prices RDL10/2022". If you are already a client of Endesa Energía, a change of tariff will involve adding this additional cost to your bill.

The price may be updated on 1 January each year by the value of the actual CPI (last General Year-on-Year Consumer Price Index officially published at the time of the update), as well as for variations in the current regulated components that apply to electricity and gas supplies, and with possible new changes that may be approved by regulation.

In case of updating with the value of the CPI, the year-on-year CPI for November, published on the website of the National Institute of Statistics ([+https://www.ine.es/+]) will be used. The update will be made by adding to the previous prices the result of multiplying the CPI by those prices. For more information, the year-on-year CPI for November 2022 was 6,8%, the year-on-year CPI for November 2021 was 5,5%, the year-on-year CPI for November 2020 was -0.8% and the year-on-year CPI for November 2019 was 0.4%.

Any changes in the regulated components applicable in the contract (upwards or downwards) will be transferred to the customer. These modifications are regulated, they are totally beyond Endesa's control and apply equally throughout Spain and to all companies.

The price may also be reviewed one year after contracting. If there were any changes, we would let you know one month in advance. Always remember that at any time you can terminate the contract or contract another tariff from Endesa or any other company without penalty.

If you get the Social Bonus, you should not apply for this tariff because you would lose it.

Once you have filled in the online contracting form and your application has been processed, it will take approximately 3 weeks to process your contract (if you were already with Endesa Energía the change is much faster).

Once the contract with Endesa has been activated, you will receive the last bill with your previous company (if you were already with Endesa it will be the last bill with your previous tariff). The first bill will be received once the first billing period with Endesa has been completed.

A One Tariff and One Gas contract has a duration of one year and is automatically renewable.

If you contract electricity with this promotion will there be no minimum duration.
