Success stories

Renovation of substations with artistic works

Conexus completed the renovation of the interior and exterior of the Bovio substation in Catania, which was part of the Street Art Challenge project: the social competition, organised by e-distribuzione in 2021, saught the most beautiful works of art created on the electrical substations across the entire country.

500 years after his death, a tribute was paid to one of the greatest geniuses in human history, Leonardo Da Vinci. On the cabin, renovated by CONEXUS, artist Francesco Ferreri reinterpreted his famous “Lady with an Ermine” in a modern key.

Snow emergency management

Conexus supported e-distribuzione in managing the snow emergency in the regions of Piedmont, Tuscany and Abruzzo. The first days of 2021 saw our colleagues working nonstop to resolve numerous outages.

High-voltage (HV) overhead and underground electrical networks

In the construction of high-voltage power lines, we deal with:

  • Excavation operations, foundation casting, erection, carpentry of simple or double backhoe supports.
  • Work on laying and adjustment of twin, triple, quad conductors and the guard rope.
  • Interventions on HV cable ducts, taking care of the design and installation of civil works.

Depending on the project, we perform different types of laying. The tubular one and the open trench one are the ones we carry out by performing trench excavation. The laying of the cable is done by winching.

Medium- and low-voltage (MV/LV) overhead and underground power grids

Our goal is to provide for their widespread deployment, managing all stages of the operational process of medium- and low-voltage power line construction.

In this context, the activities performed by us are:

  • Installation and maintenance work on overhead and underground MV/LV lines and work on electrical metering units with/without the presence of voltage
  • On-call work for troubleshooting, as well as additional activities such as supply and laying of fiber optic monotubes/pipes
  • Maintenance and possible construction of fiber optic networks on the company’s electrical infrastructure.
  • Preparatory activities for line/plant design (including celerimetric and cadastral surveys, technical drawings, etc.).
  • Ground system verification activities.

Transformer substations and substations (MV/LV)

We build, install and connect high and medium voltage electrical substations.

The skills we have acquired enable us to intervene in all aspects of an energy transformation plant, from construction to maintenance.

  • Supply, installation and testing of civil and industrial electrical systems.
  • Work on high, medium and low voltage overhead and underground power lines.
  • Work in primary HV substations.

We guarantee an intervention capacity that covers all stages of the consulting and design process, up to the installation and maintenance of the supplied systems, ensuring a complete service and the highest reliability are delivered.

Wind and photovoltaic plants

Our goal is to provide for their widespread deployment, managing all stages of the operational process of medium- and low-voltage power line construction.

Soluzioni di interconnessione Data Center alla rete elettrica nazionale

Seguiamo l’intero processo di connessione di Data Center alla rete primaria, dalla progettazione preliminare alla progettazione esecutiva, costruzione e messa in opera dell’impianto. 

We deal with:

  • Preliminary design for permitting purposes and executive design
  • Design and construction of power lines, along with cables supply and splices
  • Supply and installation of HV cable monitoring system
  • Project and construction management (EPC) for the construction of electrical substations

Electric energy storage systems (BESS)

For the client NHOA, an established company in the world of energy and electric mobility, we are responsible for the construction of the 25MW storage system on 8 BESS (Battery Storage Solution) that will serve to modulate the frequency on Terna S.p.A.’s High Voltage lines.

E-mobility charging solutions

We design, develop and manage the network of ultra and super fast charging stations with associated maintenance of secondary substations.

We deal with:

  • Design of new installations, including permit management, agronomic and geological reporting, etc.
  • 24/7 support for disconnection of charging stations in case of failure.

Installation at public or private clients of wallboxes (charging sockets for rental or private vehicles).
