Prysmian and Encore Wire unveiled a new 340,800 square-foot copper building wire plant alongside a one million square-foot service center in McKinney, Texas, marking a significant expansion of domestic wire and cable manufacturing capacity. The new service center is now one of the largest in the industry, designed to accelerate delivery times and support growing demand tied to electrification and digital infrastructure.
The McKinney campus integrates manufacturing and logistics into a unified operational model, enabling faster turnaround times, including next-day shipment capabilities and product customization. The expansion reflects increasing infrastructure requirements across data centers, industrial facilities, and grid modernization projects, where reliable supply of copper cabling remains a critical dependency. The addition of the new plant enhances production efficiency while scaling output to meet U.S. demand.
The site employs approximately 1,750 workers across the campus, including 115 employees at the new copper plant and more than 250 staff supporting the service center’s logistics operations. The investment also reinforces Prysmian’s broader strategy to evolve from a cable manufacturer into a full-service solutions provider spanning energy transmission and digital connectivity markets.
- New copper building wire plant spans 340,800 square feet
- Expanded service center reaches 1 million square feet, among the largest in the sector
- Integrated manufacturing + logistics model enables next-day delivery and customization
- Supports demand from data centers, industrial expansion, and grid modernization
- McKinney campus employs ~1,750 workers total
- Prysmian North America operates 50+ locations with ~$9B in revenue
“These two projects represent the next chapter in our story here at Encore: one of outstanding service across the board – service to our customers and to the community here in McKinney that we call home,” said Andrea Pirondini, CEO of Prysmian North America.
🌐 Analysis: The expansion underscores how physical infrastructure—particularly power delivery and copper interconnects—has become a gating factor for AI data center growth and electrification initiatives. Prysmian’s investment aligns with broader industry moves to localize supply chains and scale capacity in North America, as hyperscalers and utilities accelerate buildouts. Competitors such as Southwire Company and Nexans are also increasing investments in grid and electrification projects, reflecting sustained demand across both energy transition and digital infrastructure markets.
