The company was founded in 1974 as a consortium of five municipalities of the provinces of Florence and Siena, in order to realize the distribution network of natural gas for the citizens.
Before then, the municipalities were connected to the gas network of the single city of Siena just 4500 users, derived from the original production management and distribution of the "town gas".
In 1985, the company and the consortium integrated into a single legal entity and from 20 December 2001, the Consortium is transformed finally into a limited company.
Today, Intesa SpA is a public capital, which includes 47 municipalities members of the provinces of Siena, Arezzo and Grosseto.
The present society is set up as a multi-utility service, modern and efficient and able to offer different services to a wide range of customers throughout the energy sector.
