SELT SpA

SELT SpA is an Italian company specialising in electricity transmission and distribution infrastructure, renewable energy works and metal fabrication. Founded in 2000 and based in Sardinia, it positions itself as an energy transmission and distribution system operator in Italy, with activities extending across Europe from Greece and France to Northern Europe and other countries around the Mediterranean. Decades of experience in high‑voltage networks have made energy transmission SELT’s core business, and the company has expanded into medium‑ and low‑voltage sectors to provide flexible support to utilities and grid operators. It also develops and installs telecommunications networks, particularly optical fibre, as part of wider grid and infrastructure projects. SELT structures its activities around three main business lines: energy transmission, green energy and metal carpentry. In energy transmission it has built more than 5,000 km of power lines and maintains sites across Europe, working with customers such as Terna, Enel, RTE, Statnett, 50Hertz, Siemens, ABB, Alstom, Nexans and Vodafone. In green energy it focuses on large‑scale photovoltaic plants and wind power, contributing to projects such as the San Bellino solar park in Italy, described as the largest in Europe at the time of construction, as well as multiple wind farms and photovoltaic plants. The company executes electro‑mechanical and civil works that link renewable generation to transmission and distribution networks, acting as an interface between green power producers and distributors. Its in‑house metalworking workshop designs and fabricates bespoke steel and iron structures, from supports for electrical and telecoms works to large industrial and sports facilities, reducing reliance on subcontracted fabrication and supporting rapid delivery on infrastructure projects.
