The Aldesa Group develops its activities in the field of energy through its subsidiary Aldesa Energías Renovables. Created in 2006, it focuses its efforts on the development, design, construction and operation of wind farms and solar thermal and photovoltaic plants.

• Development: site prospecting, processing of permits, requesting access to the transport and distribution networks and to REPE (Special Registry for Energy Producers), processing of building licences (urban building and environmental impact approvals), obtaining financing, administrative authorisations.
• Construction: preparation of engineering and logistics projects, as well as those involving the management and monitoring of turnkey projects.
• Operation: maintenance and management of contracts associated with operating and running such activities.

Likewise, new projects are being analysed in fields such as biofuels and offshore wind farms that will increase the Group's share in the alternative energy sector.

Aldesa Energías Renovables has chosen North America and Eastern Europe as priority areas for its international expansion, creating companies to break into the renewable energies market in the United States, Canada (focusing on the wind and photovoltaic fields) and Poland (exclusively wind). In the mid-term, the company plans to geographically expand its renewable business into Mexico, Bulgaria and Romania.

Currently, Aldesa Energías Renovables has operations in five wind farms totalling more than 110 MW of installed power, as well as nine solar fields totalling 38.17 nominal MW, all located in Andalusia, and also 80 MW under construction.

By the end of 2011, it hopes to have an electrical production of 485,732 MWh and over 800 MW in different stages of development in Spain and abroad.
