One Luz Tariff: tariff with a fixed price per kWh

The One Luz electricity tariff guarantees a stable price per kWh every month. It is designed for those who use electricity in a stable way over the course of the entire day, or for those who don't want to worry about what time they use the most electricity.

With the One Luz tariff, you don't have to worry about when your electrical appliances consume electricity, as it costs you the same whatever time of the day or night you use them. Putting clothes to wash first thing in the morning will cost you the same as if you put them to wash at noon. You don't have to worry about the time any more.

Want to know how much each kWh costs so you can save energy?

You needn't worry any more, rather than charging by time of the day, the One Luz tariff involves a stable price per kWh. Designed for those who don't want to worry and know their bill will be cheaper.

Quick, easy and simple: All the kWh you consume will cost the same and cost less than with other tariffs. The One Luz tariff is the cheapest electricity tariff offered by Endesa. In your bill, under the energy term, we multiply the kWh you have consumed by the competitive One Luz price. And that's that, no more complications.

As it is a 100% online tariff, everything can be done online, from contracting to management, offering you much lower prices than traditional electricity tariffs and you'll save time with Endesa online billing.

Frequently Asked Questions

Prices with taxes (*)

VAT % Peak hour power term €/kW and year Off-peak power term €/kW and year T. Energía €/kWh
5% 35,732466 €/kW and year 8,439155 €/kW and year 0,183191 €/kWh
21 % 41,177413 €/kW and year 9,725122 €/kW and year 0,211106 €/kWh

(*) Prices including taxes. For electricity, the electricity tax is added (0.5% or a minimum amount of €0.5/MWh or €1/MWh, as appropriate) and for gas the hydrocarbons tax (€0.00234/kWh). To the result, VAT is added (21% or 5% as appropriate) IGIC (Canary Islands 0% or 3%, and 7% as appropriate). The following regulated costs associated with the financing mechanism for the Social Bonus are added to the prices: Fixed cost per customer (retailing) of €0.03671762/day (Mainland and Balearic Islands: €0.03874627/day taxes included for power supplies less than 10kW and, in all other cases, €0.04465046/ day taxes included; Canary Islands: €0.03690121/day taxes included for power supplies less than 10kW and for domestic clients, and in all other cases, €0.03800824/day taxes included). For supply points on the mainland, the regulated cost of financing the cap on the price of gas used for the generation of electricity is also added to electricity prices, which together with other items means an additional regulated cost to finance the measure. This regulated cost will be included in the invoice under "Maximum cost of gas RDL10/2022". If you are already an Endesa Energía customer, a change of tariff will mean this additional cost will be added 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 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.

There is no minimum duration. If you are not convinced, you can switch whenever you want. On other words, there are no penalties if you decide to leave. There are only specific conditions for some promotions or temporary special offers. Don't worry, we will let you know if this is the case.

If you have another rate, other than the Tarifa One rate, you can switch to the Tarifa One rate without any problem. However, if you have already contracted the Tarifa One rate, you cannot unsubscribe in order to contract it again.

The Tariff One contract is for one year, automatically renewable.
