Frequently asked questions

The CNMC, the National Commission for Markets and Competition, which is responsible for the proper functioning of markets in the interest of consumers and businesses, seeks to comply with a 2009 European Directive.

 Until then it has been the Ministry for Ecological Transition and the Demographic Challenge, and from this change, the CNMC will define the part of the regulated costs that cover the costs of Transmission and Distribution of electricity (called Tolls).

And the Ministry will continue to define the rest of the regulated costs, such as premiums for renewables, tariff deficits or surcharges for island systems (called Charges). 

One of the objectives of this regulation is to achieve a better balance between electricity supply and demand at different times of the day, avoiding grid saturation and encouraging efficient consumption.

It is effective from 1 June 2021.

To all electricity supplies in the national territory.

1. Change in the nomenclature and terminology of tolls and charges.
2. Modification of the schedules of tolls and charges.
3. Changes in the application of excess power tolls.
4. Incorporation of a capacitive energy term.

It changes the way in which the regulated component part of the electricity bill is calculated.

In the "Contract Details" section of the electricity bill of any Reseller, you will be able to see the Access Tariff of your supply. It can be any of these:

2.0A, 2.0DHA, 2.0DHS, 2.1DHA, 2.1A, 2.1DHS, 3.0A, 3.1A, 6.1A, 6.1B, 6.2, 6.3 and 6.4.

For your low-voltage supplies, with maximum contracted power ≤15 kW, the access tariff will change from having 1 power term and 1 energy term, to 2 power terms and 3 energy terms. Likewise, this access tariff will be renamed 2.0TD.

For your low-voltage supplies, with maximum contracted power ≤15 kW, the access tariff will change from having 1 power term and 2 energy terms, to 2 power terms and 3 energy terms. Likewise, this access tariff will be renamed 2.0TD.

For your low-voltage supplies, with maximum contracted power ≤15 kW, the access tariff will change from having 1 power term and 3 energy terms, to 2 power terms and 3 energy terms. Likewise, this access tariff will be renamed 2.0TD.

For your low-voltage supplies, with a minimum contracted power >15 kW, the access tariff will change from having 3 power terms and 3 energy terms, to 6 power terms and 6 energy terms. Likewise, this access tariff will be renamed 3.0TD.

For your medium voltage supplies, with supply voltage <30kV and maximum contracted power ≤450 kW, the access tariff will change from having 3 power terms and 3 energy terms, to 6 power terms and 6 energy terms. Likewise, this access tariff will be renamed 6.1TD.

For your medium voltage supplies, with supply voltage ≥30kV and maximum contracted power ≤450 kW, the access tariff will change from having 3 power terms and 3 energy terms, to 6 power terms and 6 energy terms. Likewise, this access tariff will be renamed 6.2TD.

Access Tariff 6.1

For your high voltage supplies, with supply voltage >1kV and <30kV, you will continue to have 6 power terms and 6 energy terms. Likewise, this access tariff will be renamed 6.1TD.

Access Tariff 6.2

For your high voltage supplies, with supply voltage ≥30kV and <72.5kV, you will continue to have 6 power terms and 6 energy terms. Likewise, this access tariff will be renamed 6.2TD.

Access Tariff 6.3

For your high voltage supplies, with supply voltage ≥72.5kV and <145kV, you will continue to have 6 power terms and 6 energy terms. Likewise, this access tariff will be renamed 6.3TD.

Access Tariff 6.4

For your high voltage supplies, with supply voltage ≥145kV, you will continue to have 6 power terms and 6 energy terms. Likewise, this access tariff will be renamed 6.4TD.

• 2.0 TD: there is now a single calendar for the whole year for mainland Spain, the Canary Islands and the Balearic Islands and a different one for Ceuta and Melilla.
• 3.0 TD and 6.XTD: will be differentiated in 5 geographical zones (Peninsula, Balearic Islands, Canary Islands, Ceuta and Melilla).

Endesa will advise you so that you only pay for the power your company needs. The new regulation includes new features that include surcharges, so we recommend that you contact us so that a personalised manager can help you optimise your power.

No. Your distributor will take care of everything necessary for you to adapt to the new regulations, so you don't have to worry about anything.

If you are an Endesa customer, nothing will change in your contract. The rest of the conditions will remain in force and the change in regulated costs will be adapted.

Your access tariffs will be adapted in accordance with the regulations.

If your access tariff was linked to the ATR calendar, your schedules will automatically change to the new schedules and calendars.

If your access tariff had a different timetable to the ATR, we will bill you under the same conditions as before for both power and energy and we will apply an upward or downward adjustment supplement to each bill that regularises the regulated costs with the new calculation method, respecting the rest of the conditions of your contract.

It is important to be clear that Endesa will maintain the terms of your contract at all times, varying only the regulated components, in accordance with the regulations of both the CNMC and the Ministry.

If you sign a new contract with Endesa, once the contract term has expired, your bills will include the new tolls and charges.

You do not have to pay more for the electricity consumed by your company. In any case, it will always depend on your consumption profile and how you adjust it to the schedules established in the regulation.

Endesa offers you personalised advice so that you can assess this regulatory impact on your company's bill.

Endesa's recommendation is that, as far as possible, you should shift your consumption to the hours when the price is cheapest and optimise your contracted power. This will enable you to make significant savings.

No. As this is a regulatory change, it is necessary to update the structure of the same, in accordance with the regulations.

Endesa will inform you of any changes in your company's electricity supply, assessing their impact on your bill in a detailed and transparent way so that you can adapt to the change with all the facilities and without having to worry about anything.

We are at your side to advise you and keep you informed at all times about new developments affecting your electricity supply.

It will only affect High Voltage supplies, that is, future tariffs 6.XTD and in the P6 time period. In the latest publication of the reference regulation, in the BOE of March 23, 2021, it has been proposed that during a transitory period this penalty will not be effective, giving customers time to adapt their facilities. However, it is possible that as of January 2022 its application will begin and its value may be revised in subsequent years. In any case, we advise clients with this type of access rates, to avoid penalties through technical and optimal solutions to compensate for this type of energy.

No, your supply contract maintains the conditions negotiated with your company and in force at the time of the change, until the expiration agreed in said contract. But as of the entry into application of the new tolls, your company will carry out a conversion of the contract in force so that it adjusts to the new toll structure. 

To adjust to the new regulations, your company will carry out an automatic conversion, with the criteria indicated in the regulation, for the powers currently contracted. However, you can request a change at any time to adjust to the new schedules. In fact, Endesa will advise customers in this regard, and we will identify the best power ratings for the new application schedule.

Your gas contract will not be affected by this change, and will continue as before. However, a change in gas tolls is planned for October by the CNMC, of which we will inform you as soon as possible.

It is another of the concepts that make up the regulated costs and are independent of the Tolls and Charges of the access fees. Its value is updated annually.

As of 1 June 2021, the value of this concept will also be updated, and on this occasion it is foreseeable that they will experience a decrease with respect to their current value.  This will mean savings on your electricity supply bill, regardless of how the changes in CNMC Circular 3/2020 impact you.

This value is included in the price of your energy, so it will foreseeably be automatically updated downwards in your price. The changes in regulated components are automatically transferred in the event of any variation, so you don't have to worry about anything.
