Prysmian Group has officially broken ground on a $500 million, multi-year expansion at the Encore Wire campus in McKinney, Texas, marking a major milestone for the city’s industrial sector and the company’s North American growth strategy.
The investment includes a previously approved $249 million allocation and represents Prysmian’s most significant move since acquiring Encore Wire last year. At the center of the project is a 650,000-square-foot, state-of-the-art medium voltage cable manufacturing facility scheduled to begin operations in 2027. The plant is expected to substantially increase Prysmian’s medium voltage production capacity while creating 120 new jobs in the region.
The expansion is designed to address rising demand driven by data centers, industrial growth across the United States, and critical upgrades to the national power grid. Company leadership highlighted the new facility as one of the largest standalone buildings on the campus, which is already recognized as the world’s largest vertically integrated cable manufacturing site.
The groundbreaking ceremony brought together local and state officials, underscoring the project’s economic significance. City leaders described the investment as a strong vote of confidence in McKinney’s business environment and long-term growth prospects. State and federal representatives also acknowledged the strategic importance of the expansion for Texas and the broader U.S. energy infrastructure.
Encore Wire, founded in 1989 with a single 68,000-square-foot building, has grown over 35 years into a 3.5 million-square-foot operation spanning 460 acres. Today, the campus serves as the core of Prysmian’s North American operations and reflects the company’s broader transformation from a traditional cable manufacturer into a comprehensive energy solutions provider.
The new medium voltage plant represents the first phase of further planned development at the site, reinforcing McKinney’s position as a key hub in strengthening the nation’s energy and industrial infrastructure.
