High-voltage


Our Experience

GCF S.p.A.’s activity in the industrial sector of high-voltage energy transmission infrastructure has recently received a significant boost following the acquisition of Ferroli & C. Srl in May 2022.

The transformation of this historic specialist company into GCF POWER S.r.l., together with the capitalization of the know-how gained over the years in Italy through contracts with SADE, ENEL and Terna Rete Italia S.p.A., and abroad - primarily in Germany and Austria - has enabled the Company to consolidate and expand its areas of activity.

Competitive Advantages

Today, the core business of GCF POWER S.r.l. consists of the construction and maintenance of high-voltage transmission lines. Due to its specificity and the high level of technological expertise required, this sector has always been regarded as highly specialized.

GCF POWER’s management and personnel boast decades of outstanding experience in managing turnkey high-voltage projects across Europe (Italy, Germany, Switzerland, Austria, Finland, the Netherlands, Romania, Sweden), as well as in Africa and Asia.

The company provides its clients with state-of-the-art equipment and specialized expertise for the construction and stringing of all types of power lines, thereby ensuring a turnkey General Contractor service, including material supply.
