The Castiglioni Group has been active in the electricity generation and distribution sector since 1952. Particular reference is made to the construction and maintenance of medium and low voltage electricity distribution systems and lines and public and artistic lighting systems, mainly on behalf of Enel Distribuzione SpA. Collaboration with the Enel Group has been uninterrupted for over 60 years, to the satisfaction of both groups.

As early as the second half of the 1950s, Castiglioni was among the first in Italy to start construction of prefabricated VRC transformer substations. They became the market standard for making MV/LV transformer substations within a short time. With the leverage of its continual collaboration with the Enel Group, Castiglioni has always distinguished itself in this segment as well owing to its offer of technologically advanced solutions with high standards of quality that still today is one of the very few Enel-APPROVED manufacturers in Italy.

With its decades-long experience, in 2008 the Castiglioni Group further expanded its product range into the energy sector. It successfully entered the market with a strong eco-friendly imprint symbolised by its design, construction and management of power plants producing electricity from renewable sources (photovoltaic, biomasses and biogases).

Today, the Group is a vigorous competitor in the sector, above all thanks to the significant contribution of BetonCablo S.p.A., a leader in the market of MV/LV power line construction and maintenance, electricity generation and distribution systems (also from renewable sources), and electrical transformer substations.
