GHESA Ingeniería y Tecnología is a Spanish engineering company initially set up for the development of projects in the electricity sector, particularly in the field of power generation. The company later underwent a broad process of diversification into other fields where synergies existed in terms of technology and management.
Established in 1963, GHESA was a collaborative initiative of major Spanish electric utilities and the American consulting engineering company, Gibbs & Hill, Inc. (NY), which took on the role of technological partner up until its share of the company was sold to its Spanish partners in 1992.

In 1971, after the launching of Phase II of the Spanish Nuclear Program, GHESA promoted the creation of the consortium Empresarios Agrupados (EA) in collaboration with other Spanish engineering companies to share capacities and resources for the development of the engineering of nuclear power stations and other macro projects for thermoelectric generation. EA’s activities are managed through an Economic Interest Grouping called EA, AIE.

At present, GHESA, with its more than 500 employees, and Empresarios Agrupados, with global resources of roughly 1000 people, form one of Europe’s most important engineering groups, with the technological and management capacities to develop a wide range of complex projects at both in Spain and internationally.
