The Citizen Revolution
Founded in 2010 at the University of Girona, Som Energia was inspired by successful European cooperatives like Ecopower (Belgium). It has grown into the largest energy cooperative in Spain, with over 85,000 members.
The cooperative operates with total transparency, with decisions made through democratic assemblies where each member has one vote, regardless of their investment.
In 2026, their 'Tarifa Periodos' provides stable 100% green energy, while the 'Generation kWh' project offers a unique way to 'own' your production through collective loans.
