You can change your electricity company whenever you want. It will depend on the company you have contracted at the time of the decision to change and the conditions of the contract that will determine the simplest and most economical process, even free of charge. 

If you have contracted the electricity in your home with MIWenergía we want you to be free to switch to another company whenever you want, so we do not apply permanence, we will work so that you want to stay with us, but without ties.

It is advisable to contact a good electrical company that can provide all the necessary information for this process and is able to design the optimal installation according to your needs and roof conditions.

It will depend on the electricity tariff you have, for a residential consumer with our Fixed Price Tariff, you can take advantage of cheaper consumption hours at nights and weekends.


We should know that there are three fundamental periods for the price according to the hours of the day, the most economical being the "off-peak hours":

  • Peak hours: In the morning between 10 a.m. and 2 p.m. and between 6 p.m. and 10 p.m.
  • Flat hours: From 8 a.m. to 10 a.m., from 2 p.m. to 6 p.m., and from 10 p.m. to midnight.
  • Valley hours: Between 12 p.m. and 8 a.m., weekends and holidays.


On the other hand, for a consumer with power over 15kW, the cheapest hours depend not only on the time of day, but also on the month of the year.

OMIE (Iberian Energy Market Operator) and the Government are in charge of setting the price of electricity. The former is the one that matches supply and demand to establish the price and the latter is the one that adds access fees and electricity distribution and transportation costs.

It is understood to be a registration of electricity when we need to register the electricity in a house or premises (if it already has electricity, it is only considered as a change of company). The supplier will manage the registration, although it will be the distributor of the area that will carry it out and charge the expenses.


The price depends on the power to be contracted, differing in the following concepts per contracted kW + VAT:

  • Access rights: 19'70‚ā¨/kW + VAT.
  • Hook-up fee: 9'04‚ā¨ + VAT.
  • Extension fees: 17'37‚ā¨/kW + VAT (only for supply points that have been disconnected for more than 3 years).

It is more economical to run the washing machine in the evening or after lunch, or during the weekend.

Coinciding with the cheapest time of the day, from Monday to Friday from 00:00 am to 8.00 am, and throughout Saturday, Sunday and national holidays. In this period the kilowatt per hour (kWh) is cheaper than in the central hours of the day.

Another of the best times to run your washing machine or dishwasher is between 14:00 and 18:00 (flat hours), where lower prices may be available.
