How is the price of electricity generated?

Generating companies make energy sale offers for each hour of the day. These offers are matched, giving priority to those that offer the cheapest electricity, until the entire market demand is covered. The last matched sale offer determines the Hourly Marginal Price, which is applied to all generators that have been matched for that hour.
The process is daily and sets the price for each hour of the following day.

Consult the following frequently asked questions to solve doubts about this legislation

Since the 1 of January, 2003, you can choose your natural gas and electricity company.

 

What does market liberalisation mean and what options does it offer?

The liberalisation of the energy market means that consumers can choose their natural gas and electricity supplier, regardless of the geographical area in which they are located, both for home and business needs.

You can switch to the deregulated market, that is, contract the supply of gas, electricity or both together, with the marketing company that, in your opinion, offers the best conditions, in a competitive situation.

 

What aspects should be taken into account when contracting an energy company?

Verify that the energy company making the offer is listed in the register of companies authorised by the Spanish Ministry of Economy. When calculating the final amount that will result from the offer, take into account the taxes on electricity and natural gas and other billable items. Since the offer may consist of several products, such as electricity, gas, or both, as well as other services, you should consider whether the overall offer meets your needs and expectations. You should also consider the quality of customer service offered by the company.

 

How much does it cost to switch from the rate market to the deregulated market?

Nothing. The change of supply from the regulated rate to the deregulated market does not entail any additional cost.

 

Is it necessary to change the meters?

In the case of supplies with a contracted power of less than 15 kW, the change to the deregulated market does not require any change, except for the mandatory installation of a power switch-controller (ICP), should there be none. In the case of supplies with a contracted power of less than 15 kW, a new metering device must be installed from 2004, whether or not the customer remains on the rate, which can be rented at an official price.

 

Who is responsible for the quality of supply?

The quality of the supply will continue to be the responsibility of the distribution companies and will not depend on the supply company you choose. Therefore, the change of company will not entail any modification in the technical quality of the supply.

Since the 1 of July, 2008, high voltage rates have disappeared to make way for a deregulated market in which each user selects the supplier offering the best conditions.

 

New steps towards to the liberalisation of the electricity market

Since the 1 of July, 2008, the liberalisation of the electricity market has been given a new boost as the general high voltage rates disappear, as well as the hourly power rate (THP) and the high voltage irrigation rates (R.1, R.2 and R.3).

 

What to do in the event that high voltage rates disappear?

The best option is to switch to the deregulated market as soon as possible, i.e. to contract your electricity supply with the supplier that, in your opinion, offers you the best conditions in a competitive situation.

 

What happens to high-voltage supplies after the 1 of July, 2008 if they were not contracted with a supplier?

From the 1 of July, 2008, the distribution company will invoice the first month the electricity consumed at the same price as the low voltage rate 3.0.2, with the reactive energy supplement and the type of hourly discrimination contracted. This means a significant increase in price.

 

Do I necessarily have to change electricity company?

Switching to the deregulated market necessarily means a change of company, but you can contract with a marketing company from the same Group as your current distribution company, as is the case with Iberdrola.

 

How do we help you carry out all the switching procedures at Ibedrola?

At Iberdrola, we make the processes easier for you, so that you don't have to worry about anything.

All you have to do is contact your assigned personal manager or call the Business Telephone number.

Current electricity rates

As established in the Spanish Royal Decree 216/2014 of 28 March [PDF], the price to be paid by consumers without the right to benefit from the voluntary price for small consumers, and who temporarily lack a supply contract in force with a supplier and continue to consume electricity, is that which results from applying the following:

The terms of the access tolls corresponding to the supply point, increased by 20%.

The rest of the terms included in the Voluntary Price for the Small Consumer (PVPC) corresponding to the consumer with access toll 2.0A without hourly discrimination increased by 20% in all its concepts.

The following tables show the prices of the access rates applicable to supplies that do not qualify for the Voluntary Price for the Small Consumer.
