Electrical Substations

ARNO is a leader in the construction, modernization, and maintenance of electrical substations. With several decades of proven expertise, we support clients in deploying reliable energy infrastructure.

Our teams of highly skilled professionals oversee the complete construction of substation projects: civil works, building architecture, installation of high- and medium-voltage equipment, as well as all electrical and control systems. Whether delivering new facilities or rehabilitating existing substations, we ensure precise execution that meets the industry’s most stringent standards.

We deliver substation solutions for a wide range of applications, from institutional and industrial facilities to major energy projects such as wind farms and transportation electrification. Recent achievements include the construction of the Des Patriotes substation in Saint-Eustache, the new 315 kV sectioning station in Anjou, and the modernization of the Nicolet 735 kV substation, among many others. We have also delivered numerous industrial substations, notably in Bécancour’s energy transition valley and for large-scale data centers.
