SeaTwirl AB has entered into an agreement to carry out a feasibility study for electrification of fish farms together with a global industrial supplier. The intention of the collaboration is to assess the use of SeaTwirl's floating vertical-axis wind turbines to provide renewable electricity to offshore-based equipment at aquaculture assets in Chile.

The feasibility study will cover a comprehensive scope, including energy demand and power system requirements, environmental site conditions, cost assessments, supply chain opportunities, and logistics in Chilean waters with the intention to reduce dependence on diesel. The study is expected to be completed during 2026, and the results will help determine next steps.

Chile is home to one of the largest aquaculture industries in the world, and the sector is pursuing ambitious sustainability goals including lower emissions, increased use of renewable power and reduced risk of spills. While the contractual value of the agreement is limited, at approximately SEK 0,8 million, the engagement will generate revenue and represent an important step in SeaTwirl's commercialization effort.

"This collaboration marks an exciting step towards our purpose to enable floating wind power wherever it is needed, and to expand the use of floating wind technology beyond traditional grid-connected applications. The aquaculture industry has a clear need for offshore renewable energy, and we believe our technology can deliver a robust and cost-effective solution. It is also a major milestone to become involved in the southern hemisphere where many of the challenges we try to address, such as limited availability of cranes, vessels, and yard infrastructure, may be more challenging than in the north. We see significant potential in the aquaculture segment and look forward to beginning this journey in South America", says Johan Sandberg, CEO of SeaTwirl.
