This large-scale initiative represents one of the most significant investments in wave energy in Europe and a vital step toward meeting Portugal’s National Energy and Climate Plan target of 200MW of installed wave energy capacity by 2030.

The VianaWave project will consist of a CorPack system featuring 30 advanced Wave Energy Converters (WECs), collectively producing around 30GWh of clean electricity per year, enough to power about 7,500 homes. By capturing the constant motion of Atlantic swells, the farm will provide a stable source of renewable energy, helping to cut greenhouse gas emissions while complementing solar and wind generation on the national grid.

Planned to begin operations between 2028 and 2029, VianaWave builds on the success of CorPower’s HiWave-5 demonstrator, which validated the company’s technology in real ocean conditions. Moving from a pilot-scale program to a commercial-level deployment is widely viewed as a milestone for the wave energy industry, signaling that the technology is ready for broader adoption.

The potential impact extends well beyond energy generation. According to the EU-funded EVOLVE study, Portugal has an estimated 15GW of wave energy potential, a vast untapped resource that could transform the nation into a global powerhouse in marine renewables. If fully harnessed, this resource could significantly strengthen energy independence, contribute to net-zero goals, and stimulate sustainable economic growth.

A key element of VianaWave is its strong local economic footprint. An estimated 75% of the project’s lifetime value will be spent in Portugal, supporting investment in engineering, construction, and operations. Onshore infrastructure upgrades will include the expansion of electrical systems in Agucadoura and Póvoa de Varzim, alongside the development of CorPower Ocean’s operational base at the Port of Viana do Castelo. This will create skilled jobs and expand industrial capacity, while embedding Portugal more deeply in the global supply chain for clean energy technology.

Wave energy offers unique advantages compared to other renewables. It delivers predictable power, day and night, regardless of weather conditions, making it an ideal complement to variable sources like solar and wind. This reliability enhances grid stability and energy security, critical factors as Portugal continues to decarbonize its economy.

VianaWave is also designed as a springboard for future growth. By proving the technology at the 10MW scale, the project aims to pave the way for gigawatt-scale deployments both in Portugal and abroad. Lessons learned here could be replicated in other coastal nations with strong wave resources, helping to accelerate global adoption of marine energy.

Beyond its technical and environmental contributions, the initiative underscores Portugal’s strategic position in the renewable energy transition. The country’s Atlantic coastline, supportive policy environment, and growing network of clean-tech innovators make it an attractive location for large-scale projects that combine environmental impact with economic benefit.

As the world intensifies efforts to achieve net-zero targets, VianaWave represents a tangible example of how targeted public funding, innovative technology, and national ambition can align to bring emerging renewable sectors into the mainstream. For Portugal, the ocean’s waves are no longer just a feature of its landscape; they are set to become a powerful driver of its clean energy future.
