The Norwegian data-centre group CTS has moved from announcement to output in Viana do Castelo. Nordic EPod, the joint venture between Oslo-headquartered CTS Group and the power-management multinational Eaton, has begun manufacturing at its new plant between the parishes of Darque and Vila Nova de Anha, in what local reporting puts at a roughly €50 million investment. The start of production was confirmed in late August, when Viana do Castelo mayor Luís Nobre visited the site.
The distinction matters. NorthSouth HQ covered the joint venture when it was signed in the summer; what has changed is that the factory is now running. Essential Business reported on 3 September that the plant currently employs about 120 people, with the workforce expected to reach 500 by spring. The Portuguese operation is led by Carlos Ribas, the former chief executive of Bosch Portugal — a hire that says something about the seniority CTS is willing to buy for an industrial build in the north.
What the plant actually makes
Nordic EPod produces Electrical Power Optimization Devices — prefabricated units that receive, transform, distribute and stabilise electrical power for data centres. These are the skid-mounted power rooms that hyperscale operators now buy as modules rather than build on site, and they sit directly in the bottleneck of the AI build-out: not chips, but the electrical plant needed to feed them.
According to figures reported by the regional outlet e24.pt, the factory occupies a 110,000 square metre site with 21,000 square metres of built area, is sized for roughly 450 units a year, and carries an order book already secured through June 2027. The same report puts projected annual turnover at €650 million and says approximately 90% of output is destined for export to European and Middle Eastern markets. Those figures come from a single regional source and should be read as company guidance rather than audited numbers — but even discounted heavily, they describe a plant built for export, not for the Portuguese market.
The expansion plan reported alongside the opening includes additional work shifts, a showroom, and a specialised training centre — the last of these being the detail that most reliably distinguishes a durable industrial investment from an assembly outpost.
A Nordic operator building a Portuguese industrial base
CTS Group, which operates as CTS Nordics, originated in Oslo and has grown into one of Europe’s larger design-and-build contractors specialising in sustainable hyperscale data-centre infrastructure. Portugal is no longer a satellite in that structure. The group established its European headquarters in Lisbon at Parque das Nações, took a majority stake in the Porto engineering firm BIMMS, and has now added manufacturing in Viana do Castelo. That is a design office, an engineering bench and a factory — the full stack, held in one country.
This is the shape Nordic industrial investment in Portugal increasingly takes. It is not a sales office chasing the Iberian market. It is a Nordic company using Portuguese engineering capacity and industrial land to serve customers elsewhere in Europe and the Gulf. Essity’s shared-services hub in Lisbon and Vestas’s technology centre in Porto follow the same logic from different sectors: Portugal as a production and capability base inside the EU, priced below northern Europe and staffed from a deep engineering pipeline.
Why it matters for the corridor
Viana do Castelo is not an obvious data-centre town. It is a shipbuilding and industrial district in the Alto Minho, and the arrival of a power-module plant with a stated 500-job target reframes what the Nordic–Portuguese relationship can mean outside Lisbon and Sines. For Portuguese suppliers — in sheet metal, switchgear, cabling, logistics and industrial services — a Norwegian-owned assembly line exporting 90% of its output is a procurement opportunity that did not exist eighteen months ago.
The risks are the ordinary ones. A ramp from 120 to 500 people inside roughly two quarters is aggressive in a tight regional labour market, and an order book that ends in mid-2027 is a good position rather than a permanent one; data-centre capital spending is cyclical, and power-module demand tracks it closely. The signals worth watching are whether the training centre is actually built, whether the second and third shifts are hired, and whether Eaton routes further European volume through Viana rather than its existing plants.
For now, the corridor has something it does not get often: a Nordic industrial commitment in northern Portugal that has stopped being a press release and started producing hardware.
