McKinney’s industrial engine just got a serious upgrade. A ribbon-cutting yesterday at the Encore Wire campus in McKinney marked the official opening of a new Copper Building Wire Plant and a significantly enlarged service center under Prysmian’s North American operations. The new plant adds roughly 340,800 square feet of production space, while the Service Center now totals about 1 million square feet. Company officials said the additions will speed deliveries and boost customization capacity for contractors, data centers and grid modernization projects.
New plant and expanded service center
Per a press release via Prysmian, the company held a ribbon-cutting ceremony to unveil the 340,800-square-foot Copper Building Wire Plant and the expanded Service Center, which Prysmian says is now the largest in the industry at roughly 1 million square feet. Andrea Pirondini, CEO of Prysmian North America, called it a historic moment for McKinney as the company celebrated both the new plant and the Service Center expansion. The release also lists staffing numbers, with about 115 employees at the new plant, more than 250 at the Service Center and roughly 1,750 people across the McKinney campus.
How the build fits Prysmian’s strategy
In an April 15, 2024 press release, Encore Wire announced the sale of the company to Prysmian, a move that preserved the single-site McKinney campus and made it a linchpin of Prysmian’s North American footprint. That alignment set the stage for a broader investment program at the site and more integrated U.S. production under the Prysmian banner, with the new plant and supersized Service Center serving as early proof that Prysmian plans to lean hard on McKinney.
Local impact and what's next
Local officials and business leaders joined Prysmian executives at the ceremony, including McKinney Mayor Bill Cox, to celebrate what city leaders called a vote of confidence in McKinney’s industrial future, per Prysmian’s release. The ribbon cutting follows a separate $500 million, five-year expansion announced in June 2025 that includes a 650,000-plus-square-foot medium-voltage plant expected to open in 2027 and create roughly 120 jobs, as reported by The Dallas Morning News. City and company officials said the campus will play a continued role supplying wiring for construction, data centers and grid modernization across the region.
Watch this space
Expect hiring announcements tied to the medium-voltage plant and continued local supply-chain activity as Prysmian ramps up production. For McKinney, the project helps cement the city’s role as a manufacturing hub for the region, with the Encore Wire campus sitting at the center of that story.
