One Light Promotion Tariff

(*) Prices with taxes. The price will include the electricity tax (5.11269632% or the minimum amount of €0.5/MWh or €1/MWh, as applicable). On the resulting amount, VAT (21%), IGIC (Canary Islands: 0% or 3%, and 7% as applicable) or IPSI (Ceuta and Melilla: 4% or 1% as applicable) will be added. The regulated cost associated with the social bonus financing mechanism will also be added: Fixed cost per customer (commercialization) of €0.019121/day (Mainland and Balearic Islands: €0.02431959/day; Canary Islands: €0.02009883/day for domestic customers with power below 10 kW and, for other cases, €0.02070180/day; Ceuta and Melilla: €0.02029982/day; all the above amounts include applicable taxes as of the start date of these prices).

The price may be updated on 1 January each year based on the actual CPI (latest officially published year-on-year Consumer Price Index at the time of the update), as well as any changes to current regulated components applicable to electricity and gas supplies, and any potential 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. 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 2025 was 3.0%, the year-on-year CPI was 2.4% for November 2024, 3.2% for November 2023, 6.8% for November 2022, 5.5% for November 2021, -0.8% for November 2020, and 0.4% for November 2019.

If any changes, either upward and downward, are made to the regulated components applicable to the contract, these will be passed on to the customer. These types of changes are regulated and are entirely beyond Endesa's control. They apply equally across the Spanish national territory and to every provider. Additionally, the price may be reviewed after one year from the contract date. If any changes occur, you will be notified at least one month in advance. You may then choose to terminate the contract without penalty, switch to another Endesa tariff, or sign up with a different energy provider.

If you sign up online at www.endesa.com, there are no penalties if you decide to leave. If you sign up through another channel, we may offer additional benefits in exchange for a minimum commitment. we’ll let you know if that’s the case. If you accept, and leave before the end of the first year, the penalty is 5% of the estimated remaining billing. The estimated outstanding charges will be calculated by multiplying the contract price without discounts at the time of termination by the estimated outstanding energy until the end of the first year of the contract.

The One Luz Tariff contract lasts for one year and is automatically renewable.

If you are an Endesa Energía customer, you cannot take advantage of the One Luz Tariff with the commitment period discount for that same supply point.

Yes, for new customers: For electricity, a 10% discount on consumption will be offered for 1 year, and one month of free electricity consumption every year. The free month is equivalent to 720 hours of consumption and includes a 1-year commitment to the electricity contract. For gas, a 10% discount will be offered on the variable term (consumption) for 1 year. For joint electricity and gas contracts, a 20% discount will be offered on the variable term (consumption) for gas for 1 year. This promotion is not valid in Ceuta and Melilla.

No, it’s not possible to choose the month when your consumption will be billed at €0/kWh. The discount will be automatically applied to the first 720 hours (30 days) of consumption from the activation of your contract with Endesa, every year and forever.

After your contract with Endesa is activated, all consumption during the first 720 hours (30 days) will be billed at €0/kWh, and the same will apply in the following years, always starting from the contract renewal date.

If you accept the commitment and decide to cancel before completing the first year, a penalty will apply equivalent to 5% of the estimated amount of energy pending supply until the 12 months from the start date are completed. This calculation is based on the contract price without discounts.

If the change is made after 12 months have passed, there will be no penalty, nor if you switch between tariffs within Endesa Energía.
