One Luz Tariff: tariff with a fixed price per kWh

The One Luz electricity tariff guarantees that your electricity will be cheap. It is for those whose electricity use is consistent throughout the day. Or for those who do not want to worry about when they use the most energy.

With One Luz, the time does not matter because using your appliances costs you the same at any time of the day or night. Putting the washing machine on at dawn will cost you the same as if you put it on at noon. You will not be restricted by any time limits.  

Instead of an hourly discrimination rate, One Luz is a tariff guaranteeing fixed and stable prices per kWh. It is for those who want to stop worrying and simply think about a cheap electricity bill.

Easy, fast and simple: all the kWh you consume will have the same low price. In your bill, we will multiply the kWh you have consumed by the competitive One Luz price. And that's it, without further complications.

Being a 100% online rate, you will do everything online, from contracting to managing your account, so you will get much lower prices than traditional electricity rates.

The Tarifa One is valid for supplies with an access rate of 2.0DHA or 2.1DHA. Also referred to as Time Discrimination.

The price of my contract, the Tarifa One contract, 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.

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 at you can terminate the contract, contract another rate from Endesa or any other company any time.

With Endesa's One rates you have no commitment to stay (unless you take advantage of a temporary promotion that involves permanence).

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.

No. If you are not convinced, you can change anytime. You have no commitment to stay and no penalties if you decide to leave.
