The most tangible sign of how deeply Nordic capital has embedded itself in Portugal’s data-centre economy is not a server hall or a hyperscale campus. It is a factory in Viana do Castelo, in the far north of the country, that has begun turning out the heavy electrical machinery that keeps data centres running. Behind it sits NordicEPOD, a €50 million joint venture between Norway’s CTS Group and the American power-management giant Eaton — and it is the industrial anchor of one of the largest, and least reported, Nordic bets in the Portuguese market.
What NordicEPOD actually makes. The plant produces EPODs — prefabricated, modular electrical power units that data centres use to distribute and protect their electricity supply. These are not commodity parts; they are large, engineered assemblies that sit between the grid and the server racks, and demand for them has exploded alongside the global build-out of AI-ready computing capacity. The consortium has said the Viana do Castelo unit is designed to produce around 450 EPODs a year, targeting an annual business volume in the region of €650 million, with roughly 90% of output destined for export to European and Middle Eastern markets.
The site and the jobs. The investment is sized at about €50 million and spans a total area of roughly 110,000 square metres, with some 21,000 square metres of built space, split between a production line for the EPOD power modules and a second area for electrical panels. The consortium committed to creating a minimum of 500 jobs, with operations phased in from the start of 2026. For a district better known for its shipyards and its estuary than for advanced electrical manufacturing, it is a significant industrial arrival — and a vote of confidence in northern Portugal’s engineering labour pool.
This is not CTS’s first move in Portugal — it is the fourth. The Viana do Castelo factory caps a build-out that has quietly turned CTS into a multi-armed Portuguese platform. The group established CTS Europe in Lisbon, where more than 50 engineers work on data-centre projects across the continent. In Leiria it launched Velox Electro, an electrical-construction arm employing more than 200 people building data centres. And through its Nordic arm it acquired a majority stake in BIMMS, a Porto-based building-information-modelling specialist with close to 100 engineers. Lisbon does the engineering, Leiria builds, Porto models, and now Viana do Castelo manufactures — a full-stack presence assembled in barely two years.
Why Portugal, and why the north. The logic is the same one drawing hyperscalers and green-industrial players to Sines and Lisbon: a deep, comparatively affordable pool of engineering talent, EU-single-market access, an Atlantic position that suits export logistics, and an industrial base in the north that can absorb advanced manufacturing. Portugal has spent the past two years positioning itself as a data-centre destination — from the Start Campus mega-project at Sines to a wave of announced hyperscale capacity — and the supply chain that powers those facilities is now following the demand into the country rather than being imported into it.
The corridor upgrade. For the Portugal–Nordic corridor that NorthSouth HQ tracks, the CTS story marks a step-change in kind. Nordic involvement in Portugal has often meant capital (a fund taking a stake) or retail (a Scandinavian brand opening stores). CTS is bringing something harder to replicate: operational know-how in one of the most demanding corners of the electrical-engineering industry, transplanted onto Portuguese soil and staffed by Portuguese engineers. That is the type of investment that tends to stay — factories and engineering centres are far stickier than store leases or minority equity positions.
Execution is the watch-item. Ramping an advanced manufacturing line to 450 units a year while hiring and training 500 people is a serious undertaking, and the data-centre power market, though booming, is cyclical and exposed to the pace of AI capital spending. An export-heavy plant is also hostage to freight costs and to demand in the Gulf and the rest of Europe. The near-term signals to watch are the hiring curve at Viana do Castelo, the first full-year production figures, and whether CTS chooses to route more of its European engineering work through its Portuguese arms as the platform matures.
What is already clear is the direction of travel. A Nordic group that could have kept its manufacturing in Northern Europe has instead chosen to build it in Portugal — and to wrap that factory in a Portuguese engineering, construction and modelling stack. It is one of the cleaner illustrations of the corridor’s maturing logic: Portugal is no longer just a place where Nordic firms build data centres, but a place where they manufacture the critical gear that data centres everywhere depend on.
