Frequent questions

A time-restricted tariff is one where the price of electricity (kWh) varies depending on the time you consume it. If you prefer a tariff in which the cost of the kWh remains stable, the One Luz tariff is for you.
The objective of time restriction is to avoid spikes in electricity demand, benefiting those who consume electricity at off-peak hours when electricity production and distribution are cheaper.
If you are able to use the majority of your electricity in lower-demand hours (off-peak and mid-peak times), you will manage to save considerably on your electricity bill. Meanwhile, the price of kWh will be higher during peak times.

With tarifa One Luz 3 Periodos, there is no commitment to stay: you can unsubscribe whenever you want, without any penalty. However, the tarifa One Luz 3 Periodos contract has a duration of one year, renewable automatically.

The price may be updated on the first of January after contracting it, in accordance with the value of the real CPI (the latest general inter-annual Consumer Price Index officially published at the time of the update), as well as because of variations suffered by the current regulated components that are applicable to electricity and gas supplies, and with possible new changes that may be approved by law.
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%.
If there are changes in the price of your contract, they will be transferred on to the customer both if they are upward or downward. This type of modification is regulated and completely beyond Endesa's control, applying equally to the entire country and to all companies.
In addition, the price may be reviewed one year after contracting. This would happen in April or October of each year. If there are any changes, we will let you know a month in advance. Remember that you can terminate the contract, contract another tariff from Endesa or any other company at any time.
