Unión Fenosa, S.A. was a leading Spanish enterprise in gas and electricity generation and distribution until its acquisition by Gas Natural in 2009.

With an installed capacity reaching 11,120 megawatts, it catered to approximately 8.9 million clients. Headquartered in Madrid, the company was chaired by Pedro López Jiménez. Previously a constituent of the IBEX 35 index, Unión Fenosa has since been integrated into the Naturgy Energy Group.

History

The company originated in 1912 under the name Unión Eléctrica Madrileña, maintaining this title until 1970 when it was renamed Unión Eléctrica. In 1982, it merged with Fuerza Eléctrica de Noroeste, S.A. (Fenosa), resulting in the formation of Unión Eléctrica Fenosa. The brand was simplified to Unión Fenosa in 2000. In 2008, the firm became part of the Gas Natural group through acquisition.
