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

This is the tariff at which the price of electricity varies according to the time at which consumption is made. The objective of this is to avoid peaks in electricity demand, with those users who consume electricity during lower-demand hours benefiting from a lower price, when electricity production and distribution is cheaper.

In the event that users are able to carry out most of their electricity consumption during lower-demand hours (morning and evening), they can benefit from a significant discount on the price of electricity. On the other hand, they will have a surcharge on their consumption during electricity peak demand times, which must be taken into account so they do not end up paying more.

In order to be able to invoice hourly discrimination tariffs, customers must have a meter that allows them to discriminate between consumption during the different time periods.

The off-peak period is the time when the price of energy is the cheapest, whereas the peak period is the time when the price of energy is the most expensive.

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.
