Why Where Your Power Cords Are Made Matters More Than It Used To

Prysmian acquired Encore Wire for $4 billion in July 2024. That deal — the largest acquisition in the global cable industry in years — was partly a bet that North American manufacturing capacity would become more valuable, not less. The reasoning behind it is worth understanding if you are responsible for sourcing power cord infrastructure.

What Happened to Global Cable Supply Chains

The 2023–2024 period was difficult for global cable procurement. European cable manufacturers faced raw material cost increases of 35% or more driven by aluminum and copper price volatility. Production delays lengthened lead times for specialty cords to 12–16 weeks or longer. Several manufacturers that had been operating on tight margins reduced production runs on lower-volume SKUs, concentrating supply in high-volume commodity products.

For most IT procurement, this was an inconvenience. For data center buildout teams working on tight schedules, it was a serious problem. A facility under construction cannot sit idle for 16 weeks waiting for C19/C20 cords in the right colors and lengths. The project economics break down. The commissioning date slips. And slipped commissioning dates on hyperscale AI data centers have an outsized cost — these facilities are being built to meet committed capacity obligations to enterprise AI customers who are not patient about delays.

The Data Center Construction Math

The scale of current U.S. data center construction makes the supply chain question concrete. 4.5 gigawatts of new data center capacity was added in the United States in 2024 alone — the largest single-year increase on record. The 2025 trajectory suggests that number will be significantly exceeded.

Each megawatt of data center capacity requires roughly 500–800 power cords in the IEC 60320 and NEMA families, plus additional NEMA and IEC 60309 connections for distribution infrastructure. A 100 MW AI-optimized facility — not an unusually large project in the current environment — requires 50,000–80,000 individual cord connections. If you are ordering those from an offshore manufacturer with a 16-week lead time and your construction schedule is 14 weeks, you have a problem.

The math is what is driving demand for domestic inventory and short lead times. This is not a reshoring ideology story. It is a practical consequence of compressed construction timelines meeting a supply chain that was not built to accommodate them.

What Domestic Manufacturing Actually Means for Buyers

There are two things domestic manufacturing offers that offshore sourcing, at scale, does not: speed and customization.

Speed: We ship standard configurations same-day on in-stock orders placed by 3 PM Eastern. Custom configurations — non-standard lengths, unusual color coding, specific cable jacket materials, custom labeling — ship in 3–5 business days. Compare that to 8–16 weeks from offshore manufacturers for anything outside their standard catalog. For a commissioning team working against a deadline, this is the difference between hitting the date and missing it.

Customization: Large data center deployments often need cords in specific lengths to meet cable management requirements. A standard 6-foot cord may be 2 feet too long for a specific rack position, creating cable management problems that add hours to installation time and reduce airflow. Manufacturing to order means you get the exact length you need, which translates directly to installation efficiency and better airflow management. We regularly produce cords in 18-inch, 30-inch, 42-inch, and other non-standard lengths that offshore manufacturers either do not catalog or have minimum order quantities that make them impractical for small-to-medium orders.

The Carbon Argument

A growing number of hyperscaler sustainability commitments include Scope 3 emissions — the indirect emissions embedded in their supply chains. A power cord manufactured in Connecticut and shipped 200 miles to a data center in Massachusetts has a dramatically lower embedded carbon footprint than the same cord manufactured overseas and shipped across the Pacific. For procurement teams at companies with published net-zero commitments and Scope 3 obligations, this is no longer just a talking point. It is an actual requirement in some sourcing criteria.

We will not pretend this drives every purchasing decision. Cost and availability remain the primary drivers for most buyers. But the cost of domestic manufacturing has become increasingly competitive as offshore costs have risen, and for buyers with ESG requirements, domestic sourcing now closes a cost gap that used to be prohibitive.

What This Means Practically

If you are planning a data center buildout — whether 1 MW or 100 MW — the procurement conversation around power cords should happen earlier than it typically does. Most facilities treat cord procurement as a late-stage item, ordered when the racks are almost ready for equipment. That works when lead times are 1–2 weeks. It does not work when lead times are 12+ weeks, and it creates unnecessary risk when your construction schedule has no float.

Early engagement with a domestic manufacturer lets you lock in configurations, get pre-positioned inventory for your specific project, and avoid the last-minute scrambles that characterize every large data center buildout we have been involved in at some point. The facilities that get it right treat power cord sourcing like they treat structured cabling — a project deliverable with a schedule, not an afterthought.
