Since 2009 the electricity market in Spain is liberalized. Any user can select the company (comercializadora) they want from the many choices that we can find in the market.

In Spain, the distribution of the electricity is done by the distribution companies (called distribuidoras) which depending on your geographical zone in Spain it will be different.

However, the electricity contract is not made any more with the distribution company but with your comecializadora. Every client selects one of the offers from the different companies (indexed prices, fixed prices, day/night prices, etc) and this company will give the user service using the distribution lines owned by the distribution company. In the electricity tariff there will be one part intended for covering the cost of the distribution companies.
