Spain’s electricity market is dominated by 3 main suppliers: Grupo Endesa, Iberdrola & Gas Natural Fenosa. Combined the 3 electricity suppliers account for an estimated 50% of the Spanish electricity market.

While still highly concentrated, a number of smaller electricity suppliers have entered the market since deregulation in 1998. There are now more than 50 electricity companies active in Spain’s electricity market.

Recent entrants have captured market share by servicing Spain’s large expat community. Dealing with local electricity suppliers has often been a frustrating experience for expats and, by providing customer support in English, providers such as Evergreen Eléctrica have been able to address many of the pain points experienced by foreigners living in Spain.
