Born in Madrid, he is an Industrial Engineer from the Polytechnic University of Madrid. He began his professional career at Siemens in 1975, where he worked as a design and process engineer until 1981. During this period, he participated in the development of various electronic circuits and automation systems, such as those for the Trillo Nuclear Power Plant. From 1981 to 1985, he worked at PA Technology in Cambridge (UK), a company dedicated to designing electronic systems and equipment for third parties.
During this period, among other projects, he worked on the applications of amorphous silicon for the production of photovoltaic solar cells, which were in their early development stage at the time. Upon returning to Spain, he participated in the creation of PA Technology España, where he served as President and CEO.
In 1986, he joined Alcatel as Marketing Director for new products. That same year, Spain took on the presidency of a European program for the first time, the Eureka program, and he was asked to lead its management, taking a leave of absence from Alcatel. He remained in this role and later spent an additional year as Deputy General Director at the CDTI (Center for Industrial Technological Development).
In 1988, he returned to Alcatel as General Director of Industrial Electronics and a member of the Management Committee. During this period, he played a key role in the creation of ISOFOTON, the first Spanish company specializing in the design and production of photovoltaic solar cells, including bifacial solar cells. He remained on ISOFOTON’s board until its sale by Alcatel.
Starting in 1993, he served as President of Alstom Spain, the leading high-speed train company in Spain at the time, where he established the largest railway manufacturing plant in the country.
In 1995, he returned to Siemens S.A., holding the following positions successively:
- Vice President and CEO,
- Executive President of Siemens Group in Spain,
- President of the Southwestern Europe Region.
The Siemens Group in Spain employed 7,000 people, covering all branches of the parent company and operating five factories. Under his leadership, Siemens S.A. grew from an annual revenue of €700 million to €3 billion by 2006. Additionally, it was twice recognized as the best Siemens AG subsidiary worldwide. A key achievement of this period was the sale and execution of the Madrid-Barcelona high-speed rail (AVE).
In 2006, he was appointed Vice President and member of the Executive Committee of Siemens AG, as well as President of the Telecommunications Division, based in Munich, the headquarters of Siemens AG. At the time, Siemens AG had over 500,000 employees in 193 countries, while the Telecommunications Division alone had more than 75,000 employees in over 80 countries.
From 2009 to 2012, he served as Executive Advisor to the CEO of Siemens AG.
Upon returning to Spain, he was appointed President of FerroAtlántica, part of the Villar Group, a leading company in ferroalloy and metallurgical silicon production. One of its key innovation projects was the development of solar cells based on metallurgical silicon, a more cost-efficient process than the traditional chemical production of wafers and solar cells.
From December 2010 to December 2017, he was President of UNESA, the association representing Spain’s five largest electricity companies. He was also appointed Board Member of Eurelectric, the European association of major electricity companies.
One of his primary responsibilities during this period was contributing to the rationalization of the renewable energy sector and its integration into the electricity market.
The sector had been in disarray since 2007 due to an incoherent compensation structure, leading to a tariff deficit of approximately €30 billion, which was resolved under his presidency.
He has been, or continues to be, a board member of several companies.
From 2010 until its divestment, he was a Board Member of Tecnocom and Chairman of its Audit Committee.
