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.

To the total you should add VAT (21%), IGIC (Canary Islands 0% or 3%, and 7% as appropriate) or IPSI (Ceuta and Melilla: 4% or 1% as appropriate). To the prices will be added the regulated cost associated with the financing mechanism of the social bonus: Fixed cost per customer (marketing) of 0,012742€/day (Peninsula and Balearic Islands: 0,01620663€/day; Canary Islands: 0,01339331€/day for domestic customers with power of less than 10kW and, for all other cases, 0,01379573€/day; Ceuta and Melilla: 0,01352785€/day; all the above amounts include taxes applicable at the effective date of these prices).
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 an update based on the CPI, the year-on-year CPI for November will be used. It is published on the National Statistics Institute website (https://www.ine.es/). The update will be made by adding the result of multiplying the CPI by the previous prices to the existing prices. For more information, the year-on-year CPI for November 2024 was 2.4%, the year-on-year CPI for November 2023 was 3.2%; for November 2022, it was 6.8%; for November 2021, it was 5.5%; for November 2020, it was -0.8%; and for November 2019, it was 0.4%.

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 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.
