ELC ELECTROCONSULT FROM 1955

Welcome to ELC Electroconsult: Pioneers in Engineering Excellence

Founded in Milan in 1955, ELC Electroconsult has been at the forefront of providing specialized consulting services for Hydropower, Geothermal, Electrical, and Civil Engineering projects. Born from the collaboration of three iconic Italian industrial leaders – SADE (Società Adriatica di Elettricità), a pioneering electric utility company; FIAT (Fabbrica Italiana di Automobili Torino), a global automobile manufacturer; and Montecatini, a major player in mining and chemicals – ELC was built on a foundation of innovation, expertise, and industrial excellence.

In the following years, ELC strengthened its capabilities by acquiring Hydro, International Hydrotechnical Engineering Company, a Milan-based firm established in 1949 with a proven track record in civil, hydraulic, and power engineering projects worldwide. This acquisition consolidated ELC’s expertise in delivering integrated design and supervision services across diverse engineering disciplines.

Drawing from the extensive experience of its founders and Hydro, ELC Electroconsult has been instrumental in shaping major projects in hydraulic, electrical, and civil engineering. Since its inception, the company has been deeply involved in designing, supervising, and managing the construction of numerous landmark projects, both in Italy and internationally.
