The Company originated from the «Consorzio obbligatorio fra i Comuni del Bacino Imbrifero del Fiume Piave» (a collective consortium including the majority of the municipalities overlooking the river Piave, in North East Italy) established in 1956 with the aim to collect all the leases due by hydroelectric companies which taking advantage of the stream of Piave river to product electricity, and employing that amount in order to develop the natural gas pipes network. Through the years the pipes network was increased from the initial 34 Consortiated municipalities to other 58 bordering municipalities, which stipulated specific agreements with Consorzio B.I.M. Piave.
In 1996 the Consorzio B.I.M Piave sold his businesses to a new company called A.S.CO. Piave (Azienda Speciale Consorziale Piave) that, in December 2001, after the merging of Consortiated municipalities with Agreeded municipalities, turned into a Limited Company (Società per Azioni) and so getting his actual business name Ascopiave S.p.A..
