The Estra Group is a young company founded in 2009, when three Tuscan multi-utility groups (Consiag S.p.A., Intesa S.p.A. and Coingas S.p.A.) decided to join together to exploit synergies in the sale of natural gas and electricity and to become a new major player in Central Italy. The result of this process was Estra, a company dedicated to the sale of natural gas and electricity.
