NKT on 21 October 2026 inaugurated an expanded power cable factory in Esposende, Portugal, after investing €50 million to increase production capacity for medium- and high-voltage cables at the coastal site.
Scope of the upgrade
NKT said the program modernized manufacturing lines and supporting infrastructure to raise throughput of MV and HV power cables. While the company did not disclose the precise capacity uplift or added floorspace, the investment focused on new production equipment, process automation, and logistics improvements to shorten lead times and strengthen quality control. The Esposende site will concentrate on utility-grade MV distribution cables and selected HV transmission products that support onshore grid reinforcement and interconnection projects. The plant’s commissioning follows a staged ramp-up, with commercial output expected to scale progressively following the inauguration.
Why it matters for the cable sector
Europe’s accelerating grid build-out is stretching cable supply chains as transmission system operators and utilities advance substation upgrades, interconnectors, and renewable integration projects. By adding MV and HV capability in Portugal, NKT deepens regional manufacturing capacity within the EU, an increasingly important factor for project risk management, logistics, and qualification requirements. Additional capacity in southern Europe can also ease cross-border bottlenecks, diversify manufacturing footprints, and provide proximity to Iberian onshore wind and solar buildouts, industrial electrification projects, and urban grid reinforcement.
Industry context and competitive implications
Cable suppliers have reported strong order books across MV and HV segments, with procurement lead times extending on certain product classes amid overlapping infrastructure programs. Esposende’s expansion positions NKT to compete for near-term tenders in distribution upgrades, interconnectors, and renewable tie-ins while complementing its broader European manufacturing network. The announced scope suggests a focus on scalable throughput and repeatable product families—areas where standardization and process automation can compress delivery schedules and stabilize costs. While the company has not published annual nameplate output, incremental European capacity typically supports improved schedule resilience for multi-year grid portfolios.
What to watch next
Key details still to be confirmed include the magnitude of the capacity increase, the mix between MV and HV product lines, and expected ramp timing to steady-state output. Procurement teams will also watch qualification milestones, cable testing data, and logistics performance from Esposende as the site absorbs additional production. For utilities and EPCs facing congested delivery windows, an expanded Portuguese footprint may widen sourcing options for 2027–2028 programs and help de-risk project sequencing across the region.
