We want to keep growing to bring new physical and cultural energy to our customers and to the country.

We are a family business that challenges the energy giants to become the fifth biggest company on the Italian panorama and the leading private-sector group in Italy in terms of customers supplied. We are a single company that encompasses four different entities: Illumia, Wekiwi, E-wide, EnergyUp.

We are a Group full of positive energy which we share with our customers so we can grow and change together.
