Prysmian's $1B plant shows the data center trade's next layer

The data center trade's next layer is being built in Catawba County, North Carolina, where Prysmian North America is spending more than $1 billion to add 900,000 square feet to the cable factory it runs in Claremont, an expansion that comes with 385 new jobs and a completion date in 2030.

The addition, 15 miles from Charlotte, includes a glass manufacturing facility, added cable production capacity and an expanded research and development center, according to Connect CRE. The plant makes the fiber-optic cable that broadband expansion, 5G and 6G networks, and the high-capacity digital infrastructure of data centers all run on. The coverage describes Prysmian as a key supplier to the data center industry, and its Milan-based parent as the world's largest manufacturer of cables and systems for energy and telecommunications.

Read as real estate, this is a data center story with a manufacturing address. Capex that has been chasing colocation shells now looks to be arriving one layer down, at the glass and the fiber, and it is arriving in a single county where, as this publication has argued, the data center trade now lives in power, land, and the local calendar that prices both. At 900,000 square feet the addition is a plant rather than a distribution box, and plants price off utility capacity, labor draw and site buildability in ways that a warehouse lease never has to.

What the coverage does not say is whether Prysmian owns or leases the Claremont site, or what the county put on the table to land the expansion. Those are the two figures an industrial investor would want first, and their absence is a reminder that the headline dollar amount is rarely the number that resets local land values.

Shell delivery schedules in the data center sector are quoted in quarters, so a manufacturing build that stretches five years suggests the constraint has moved upstream to the equipment that fills a campus rather than the campus itself. If that constraint on fiber and glass is durable, industrial land around Claremont is a beneficiary regardless of who signs the next campus lease.

The supply chain now puts roots down in counties already competing with the data centers they supply for power, for skilled labor, for sites with the utilities to serve them. Prysmian has committed a billion dollars and five years to Catawba County on that read, and the number to watch between now and 2030 is whether the glass line and the cable lines come up on the same schedule.
