Some of the heaviest mechanical work behind Norway’s data-centre boom is being done by a Portuguese engineering group from Maia. Mecwide, through its dedicated Nordic arm Mecwide Nordics, is the mechanical partner of CTS Nordics AS on what is billed as the largest data-centre project in Norway — a 150 MW campus at Hamar — and is at the same time executing a separate expansion at a second Norwegian site in Kristiansand. It is one of the clearest examples of the corridor’s underreported half: Portuguese industrial capability flowing north into the Nordic market.
A 150 MW campus, built three buildings at a time. The flagship contract is the OSL2-Hamar data centre, first announced in March 2023 and described by Mecwide as one of the largest in Europe. The first building is already watertight with mechanical works progressing, while construction of a second building is under way. On site, Mecwide’s teams are installing some 6.5 kilometres of chilled-water piping, along with heat exchangers, tanks and pumps, across three state-of-the-art buildings — the cooling and fluid backbone that keeps tens of thousands of servers within their thermal envelope.
A second Norwegian front in Kristiansand. Mecwide Nordics is also delivering what it calls the North Project, an expansion of an existing data-centre building in Kristiansand with an estimated duration of around six months. The first phase — installing piping inside a data hall — is complete; the ongoing second phase extends the primary and secondary piping, adds four new heat exchangers and eight new water pumps, and brings a second data hall online. Repeat, multi-phase work of this kind is the clearest signal a contractor has earned a client’s trust on uptime-critical infrastructure.
Who Mecwide is. Mecwide is a Portuguese industrial-engineering and EPC group headquartered in Maia, in the Porto metropolitan area, specialising in piping, metalwork and mechanical construction for demanding industrial environments — energy, mining, oil and gas, and now data centres. To pursue Nordic contracts it established Mecwide Nordics, registered in Sweden as Mecwide Nordics Sweden AB in Stockholm, and it publishes a statement under Norway’s Transparency Act — the kind of in-market compliance footprint that distinguishes a committed entrant from an opportunistic exporter.
Why the Nordics, and why now. The Nordic region has become Europe’s data-centre frontier: abundant low-carbon hydropower, a cold climate that slashes cooling costs, dense fibre, and stable grids have pulled in hyperscale capital from Bulk Infrastructure, CTS Nordics, Vattenfall’s partnership with Nscale, and Google’s multi-hundred-million-euro Norwegian build-out. That wave needs specialist mechanical contractors who can install cooling and power infrastructure at scale and on schedule — and Portuguese EPC firms, competitive on engineering talent and cost, are increasingly the ones winning that work.
The corridor runs both ways. The relationship is even more telling because Mecwide’s Norwegian client, CTS, is simultaneously investing in Portugal: its NordicEPOD joint venture with Eaton is building a €50 million factory in Viana do Castelo to manufacture power-distribution units for data centres. So the same Nordic data-centre ecosystem that hires Portuguese contractors to build its halls in Norway is also choosing northern Portugal as an industrial base to manufacture the gear that goes inside them. The Portugal ↔ Scandinavia data-centre supply chain has quietly become a two-way loop.
What to watch. Data-centre mechanical work is unforgiving — cooling redundancy, leak-free piping and commissioning timelines leave no margin for error — so a Portuguese firm holding multiple concurrent Norwegian mandates is a meaningful credential. The signals to track are further CTS Nordics awards, whether Mecwide extends beyond Norway into Sweden, Denmark and Finland, and how quickly the Nordic hyperscale pipeline converts announced megawatts into commissioned halls. For Portugal’s engineering sector, the Hamar campus is proof that the corridor’s northbound lane carries more than wine and software.
