Prysmian recently held a ribbon cutting ceremony for the company’s $63.8 million expansion project, which has added 100,000 sq ft and 80 new jobs to its existing plant in Du Quoin, Illinois. The ceremony also commemorated the facility’s 60th anniversary.

Prysmian’s produces cabling used for renewable energy projects and electric vehicle (EV) infrastructure. The expansion has also helped modernize the existing infrastructure and implement an energy management system within the facility.

The expansion project also includes a new solar farm, which generates approximately 50% of the power needed to produce product at the Du Quoin plant.

“This investment in our Du Quoin facility reaffirms our longstanding commitment to innovation, sustainability and the Southern Illinois community that has supported us for six decades,” said Andrea Pirondini, CEO of Prysmian North America. “These brand new lines position us to meet the urgent needs of utilities, grid-hardening initiatives and the rapidly growing AI and data-center economy.”

In partnership with the Illinois Department of Commerce and Economic Opportunity, this expansion was supported through the state’s Reimagining Energy and Vehicles in Illinois initiative.

“Delivering some of the nation’s most reliable service to over 9 million people across northern Illinois reflects our ongoing investments in infrastructure and our strong partnerships with local manufacturers like Prysmian,” said David Perez, EVP and COO of ComEd. “We’re proud to collaborate with Prysmian to deploy state-of-the-art equipment that strengthens the grid, supports Illinois’ clean energy transition, and meets the evolving needs of our customers. We congratulate them on their expansion in DuQuoin and look forward to continued progress together.”

Prysmian’s Du Quoin facility was established in 1965 and currently produces custom CL Advantage medium voltage collection cables, used to conserve energy by reducing line loss during transmission. The cables are used for wind and solar energy applications and are a key component of underground substation and distribution systems. Prysmian’s Illinois plant also manufactures key components for a variety of solar energy systems, as well as specialized cables that deliver electricity to EV charging stations and modernized homes designed for enhanced energy and grid efficiency.
