New state tariff change in the electricity bill 1 June 2021

It is a reform approved by the Spanish government’s Ministry for Ecological Transition and the Demographic Challenge, together with the National Commission for Markets and Competition (CNMC).

At the Spanish level, tariffs (which are set by the CNMC and are used to pay for the transmission and distribution network) are separated from charges (which are set by the Ministry and are used to cover system costs that depend on energy policy). The CNMC (Comisión Nacional de los Mercados y la Competencia) has decided to distribute the cost of the grid among the users, and to group them by voltage and power level. Another CNMC criterion has been to distribute the cost by hourly periods, in order to encourage energy demand during off-peak hours and thus improve efficiency in the use of the transmission and distribution grid. On the other hand, there is a desire to promote electrification (also in air conditioning and mobility).

In conclusion, with these changes the government seeks to raise consumer awareness so that consumers are responsible for making their electricity bills cheaper or more expensive.

YES, to you and to all people with an electricity supply contract, regardless of the electricity company that bills you.

All electricity suppliers have had to adapt to this new structure, an important change, in which not only the electricity companies have had to adapt, but also the distributors, who are responsible for reading consumers’ meters, as it is a global change for the whole of Spain.

In addition, the government adds a new regulated cost, the Charges, which will be added to the rest of the costs of the electricity bill.

In conclusion, the price of power (fixed term) falls and the price of energy (variable term or consumption) rises.

Tariffs for supplies of up to 15kw of contracted power are unified in a new access tariff called 2.0TD (i.e. all consumers on tariffs 2.0A, 2.0DHA, 2.0DHS, 2.1A, 2.1DHA and 2.1DHS will now have the 2.0TD tariff).

They will also have 3 different energy tranches (depending on the time of day) and 2 different power tranches. The HIGHEST period will have the most expensive prices, the MIDDLE period will have average prices and the LOWEST period will have the cheapest prices.

  • PEAK schedule (high prices): Working hours from 10:00h to 14:00h and from 18:00h to 22:00h.
  • MEDIUM schedule: (average prices): Weekdays from 08:00h to 10.00h, from 14:00h to 18:00h and from 22:00h to 00.00h.
  • LOWEST schedule (cheaper prices): Working hours from 00.00 to 08:00h and on Saturdays, Sundays and national holidays.


All 3.0A access tariffs will be changed to 3.0TD tariffs, with 6 power and 6 energy tranches, and will also be billed in six hourly tranches depending on the season. For more information call us free on 900 877 555.

  • The fixed power term, which depends on the contracted power: this is a fixed cost depending on the power you have contracted.
  • The energy term: this is a variable cost, the amount depends on the energy you have consumed at any given moment (according to the new established time slots).
  • The cost of renting metering equipment or meters
  • In some cases you may have value-added services (maintenance or various insurances).
  • Finally, taxes.

Regarding the fixed power term: According to the government’s indications, consumers who are able to reduce their power during peak periods will be able to reduce their electricity bills even further. In any case, it is not advisable to lower the power until you have at least a two or three bills with the new structure, so that you can better assess whether it is really possible to lower some of the power without the lights constantly going off in your home.

Regarding the variable term or consumption: According to the government, consumers who are able to shift a large part of their consumption to the early morning or weekends will be able to reduce their electricity bills.

Taking into account the difficulty to stop consuming on weekdays, we advise you to at least avoid the PEAK hours, which are both in the mornings from 10:00 to 14:00 hours and in the evenings from 18:00 to 22:00 hours.

As far as possible, avoid the use of energy-consuming household appliances during peak hours, such as washing machines, dishwashers, electric hobs, ovens, irons, air-conditioning or electric heating.

Anything you can put on after midnight or on weekends will help keep your electricity bill down.

Knowing that this is really difficult, at least avoid peak hours on weekdays as much as possible, otherwise, the higher price to be paid for energy can far outweigh the lower price to be paid for the fixed term and raise your electricity bill.

Despite the new costs that the Government has included in this new tariff structure, at Luz Solidaria we continue with our philosophy of helping and attending to the consumer, being sustainable and continuing to help in solidarity projects, mainly focusing on all those Foundations that already collaborate with Luz Solidaria.

As soon as we have some background information, i.e. the consumer already has two or three bills with this new structure in which we can analyse their consumption profile and their power, we will carry out free studies for all Luz Solidaria customers who wish to do so in order to try to optimise their power so that they can at least reduce their fixed term costs a little.

From Luz Solidaria, we are aware that it is a big change and also complex, unfortunately it is totally imposed by the Government and we cannot do anything other than translate what is published by Law, but we will always try to help and clarify any doubts to our consumers in the easiest and simplest way possible, and as we are doing so far, we will always recommend the best option for each of them in a totally personalised way.
