Stockholm-headquartered Swedish wave-energy pioneer. Operates a manufacturing and assembly base in Viana do Castelo, northern Portugal, with the C4 wave energy converter deployed at the Aguaçadoura test site off the coast of Póvoa de Varzim, exporting up to 600 kW peak power into the Portuguese grid — the most advanced grid-connected wave-energy demonstration in Iberia.
CorPower Ocean was founded in 2012 in Stockholm to commercialise a phase-controlled point-absorber wave-energy converter, with a design that mimics the pumping action of a beating heart. The company chose Viana do Castelo as its operational base for in-water deployment, leveraging the Atlantic wave climate, existing shipyard supply chain and Portuguese maritime engineering talent.
The C4 device was installed at the Aguaçadoura wave-energy test site — the same offshore zone used in earlier Portuguese wave-energy pilots — and has been connected to the Portuguese national grid. Peak instantaneous output of around 600 kW makes it the most advanced live wave-energy demonstration in Iberia and one of the highest-performing in the world. CorPower’s long-term roadmap targets large multi-unit farms exportable to Atlantic markets, with Portugal as the lead industrial base.
CorPower is a textbook case of Swedish ocean-tech IP combined with Portuguese maritime engineering capacity. The corridor logic — Swedish R&D, Portuguese deployment site — mirrors the pattern seen in Vestas (Porto R&D centre), Stolt Sea Farm (Tocha aquaculture) and Norsk Hydro (Avintes extrusion), reinforcing northern Portugal as Scandinavia’s favoured Atlantic operating base.
