The company was formed in 1944 as Empresa Nacional de Electricidad, S.A. and changed its name to Endesa, S.A. in 1997. In September 2004, it took control of the French company SNET (Société nationale d'électricité et de thermique). This was followed by the downsizing of 30% of SNET's employees.[2]


In September 2005, Barcelona-based Gas Natural made a bid for Endesa, whose board unanimously immediately rejected a €23 billion (£16 billion) offer.[3] On January 5, 2006, the Tribunal de Defensa de la Competencia (Competition Court, TDC) blocked the merger of Gas Natural and Endesa because of what it claimed would be irreversible negative impacts on competition. For most of 2006 and 2007, Endesa was the target of rival takeover bids by Germany's E.On and the Italian firm Enel. Despite Gas Natural being half the size of Endesa,[4] its bid was championed by the then-Socialist government as an all-Spanish deal, but Gas Natural decided to withdraw its bid after the German firm E.On offered a higher bid for the company.[5] The opposition People's Party of the day, and some Madrid politicians, criticised the bid, alleging political interference by the Socialists and a Catalan nationalist plot to control energy supply respectively.[3]

On 2 February 2007, E.On offered €38.75 for each share of Endesa. The German firm withdrew its bid two months later in exchange for a promise from rival bidders to sell it part of the Spanish utility's assets.[6] SNET, Endesa Italia and Enel's Viesgo were amongst the business units ultimately sold off to E.On.[6] Acciona and Enel succeeded in their joint bid to acquire Endesa in October 2007 for an estimated €42.5 billion[7] and they announced later that month that they jointly held 92.06% of Endesa's share capital[8] (25.01% Acciona and 67.05% Enel) as a result of their 100% takeover bid launched on Endesa, with the remaining 7.94% being free float.

The two companies initially jointly managed Endesa through an Acciona-controlled holding company which held 50.01% of Endesa's share capital, but in February 2009 Enel agreed to buy out Acciona's stake, taking its total ownership to over 92%.[9] Some Endesa assets will be sold off to Acciona as part of the deal.[9]

As of September 2015, ENEL owned 70.1% of Endesa's share capital.[10]

Electric vehicleEdit

In Europe, Endesa is the only Spanish company involved in the ELVIRE (Electric Vehicle Communication to Infrastructure, Road Services and Electricity Supply)[12][13] and G4V (Grid for Vehicles)[14] consortia aimed at developing the necessary technology, solutions and services to enable ongoing interaction between drivers, their power suppliers and the smart grid.

The Chairman of Endesa, Borja Prado, together with the mayor of Madrid, Alberto Ruiz Gallardón, and the Chairman of Telefónica, César Alierta, have the phone booth in Madrid which can also be used for recharging electric vehicles. Reserved parking spaces will be located next to this and all other booths set up in Metropolitan areas where users will be able to park their EVs and recharge at no cost once they have obtained their free "zero emissions" pre-paid card from the Madrid city council.[15]
