One Luz 3 Periodos Tariff

The One Luz 3 Periodos tariff ensures that the electricity you consume will work out cheaper if you use it between 12:00 a.m. and 8:00 a.m. on weekdays, and whenever you want on weekends and public holidays.

With One Luz 3 Periodos, you will save money and your energy consumption will be organised into three different times:

  • Off-Peak Hours: these are the cheapest hours and range from 12:00 a.m. and 8:00 a.m. on weekdays, and 24 hours a day on Saturdays, Sundays and national holidays.
  • Mid-Peak Hours: these are moderately priced hours and range from 8:00 a.m. to 10:00 a.m., from 2:00 p.m. to 6:00 p.m. and from 10.00 p.m. to 12.00 a.m.
  • Peak-Hours these are the least cheap hours and when you have to try not to consume a lot of electricity. They run from 10:00 a.m. to 3:00 p.m. and from to 6:00 p.m. to 10:00 p.m.

One Luz 3 Periodos offers you 8 hours a day with a very cheap price of electricity. Between 12:00 a.m. and 8:00 a.m. is when you want to concentrate your electricity consumption. And on weekends and national holidays this time extends to 24 hours a day.

The One Luz 3 Periodos tariff fits you if you want your day-to-day actions to help you save on your electric bill. If you're willing to change your habits to become more efficient, this restricted time tariff is for you.

One Luz 3 Periodos boosts energy efficiency by reminding you that every time you use an appliance, you're using energy that could be more or less cheap depending on the circumstances.

(*) The regulated cost associated with Social Bonus financing mechanism will also be added to the prices: Fixed cost per client (retail) of €0.03053965/day (Mainland and Balearic Islands: €0.03222697/day including tax for powers less than 10kW and, in all other cases, €0.03713774/day including tax; Canary Islands: €0.03069235/day including tax for domestic clients with powers less than 10kW and in all other cases, €0.03161312/day including tax). 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.

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.

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 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.
