Independent service provider for all actors in the renewable energy sector

“Vires Acquirit Eundo”

ISEG does not lead in terms of size in any of the geographical areas in which it is present, but the quality achieved in all its services and their diversity, the number of geographical areas in which it has commercial activities, as well as the professional traceability of its management team and the involvement of each and every one of its employees makes it an independent supplier of services to the production of renewable energies that is fully transactional, reliable and with solid growth at a global level, which allows it to compare itself with or exceed any of the leading companies in any of its areas of action.

Founded in the first decade of the 21st century, in a European country (Spain) where the renewable energy sector was already reaching a certain maturity and global leadership (third largest producer at that time and fifth at present), ISEG has managed to make its way and consolidate itself as a reliable company, with solid and sustained growth, with a clearly international vocation (with a subsidiary in France and an investee company in the United Kingdom).
