SO Tax Reg. Sondrio Tribunal Reg. Soc. 1152/1 CCIAA Sondrio n.23345 Our history Colsam was born in Valtellina in 1937 marketing heating products. At the end of the 1940s he became a partner of the ENI group, assuming its representation in the distribution and trade of petroleum products for the province of Sondrio. Over the years, the professional skills and constant commitment of the staff have led the company to equip itself with adequate structures necessary to handle an ever-increasing range of energy products. In 2003, following the liberalization of the natural gas market and the progressive methanisation of the territory, Colsam Energie was born, which deals specifically with the sale of methane gas on the free market. The two companies form a solid group that has been able to grow and conquer new markets: from Valtellina to Valchiavenna up to the Provinces of Lecco, Como and Brescia. All this without ever losing sight of one's goal: to satisfy the customer's needs, guaranteeing an optimal service in full respect of the environment, thanks to the help of qualified personnel, grown in the company and with the company.
