In 2010 the Company's portfolio of projects surpassed two billion Euros. 84% of this Project portfolio is abroad, demonstrating the progressive and intensive internationalization of Company activity in the last few years. The strategic areas for international expansion are the United States, United Kingdom, Latin America, Middle East, Russia and the Eastern European countries. The increase in activity in recent years is a product of the Company's change of strategy, begun in 2004, when it directed its activity to engineering and construction, principally of electric installations for power generation, distribution and control. Likewise it executes important projects throughout the world in the nuclear and renewable energy sectors with a high component of R&D&i. The search and consolidation of foreign markets and the service rendered to its parent company IBERDROLA through the experience and know-how acquired as one of the foremost electric engineering companies in the world, comprise two of the Company's driving forces in strategic planning. In that respect, the high level demonstrated by the Group in its management systems for quality, environment, occupational risk prevention and R&D&i initiatives, increasing their value through a sustained focus on product improvement, must be emphasized.
