French company Seaturns, a wave energy technology developer announces the launch of its first pre-commercial offshore project in Mauritius Island.

Seaturns has been selected as a winner of the NSEPCRET Round 3 call for projects (National Scheme for Emerging Project Concepts Based on Renewable Energy Technologies), led by the Mauritius Renewable Energy Agency (MARENA). This scheme aims to support innovative renewable energy technologies and provides a Power Purchase Agreement (PPA) with the Central Electricity Board (CEB), the national utility of Mauritius.

A 2 MW pilot farm connected to the grid, with a scale-up to 10 MW. This project represents one of the world’s first pre-commercial offshore deployment of a wave energy farm connected to a national electricity grid.

In its first phase, the project involves the installation of a 2 MW array of wave energy converters connected to the Mauritian electricity grid, to demonstrate the industrial performance and reliability of Seaturns technology under real operating conditions.

Depending on the performance achieved during this pilot phase, an additional 8 MW might be deployed, bringing the total capacity of the wave energy farm to 10 MW.

This project contributes to the diversification of Mauritius’ energy mix, as promoted by the Mauritian Government, and to strengthening security of electricity supply in the context of the country’s energy transition and economic growth.

Technology Designed for Island Territories

By choosing wave energy, Mauritius is making a strategic choice. This highly predictable energy source will play a key role alongside existing baseload generation, helping enhance energy security.

Seaturns differentiates itself through the advantages of its technology for island territories:

• Simple design enabling rapid manufacturing anywhere in the world
• Scalable solution adaptable to site-specific conditions
• Highly competitive CAPEX thanks to streamlined engineering
• Optimized OPEX through offshore-maintainable systems
• Low visual impact supporting social acceptance
• Reduced marine footprint through shared anchoring systems

The technology is designed to withstand the harshest marine environments while ensuring continuous, reliable, and economically competitive renewable energy production.

A Mauritian Industrial Partnership

The project is being developed with the support of Taylor Smith Group (TSG), a major industrial player in the Mauritian maritime sector.

Founded in 1856, the group operates a Marine Cluster specialized in maritime services, port operations, logistics, and offshore activities.TSG has recently strengthened its manufacturing and industrial refurbishment capabilities, consolidating its position as a strategic maritime hub in the Indian Ocean.

This partnership enables local manufacturing of the floaters, as well as deployment, installation, and maintenance of the equipment using skills and infrastructure based in Mauritius. It also contributes to the development of a regional industrial value chain for Seaturns.

A Strategic Step Toward Commercialization

With this first pre-commercial project, Seaturns confirms its ability to rapidly design and bring its innovative wave energy solution to the market — a technology specifically adapted to the constraints of island grids, particularly in Mauritius. Seaturns aims to develop several commercial pilot farms by 2030.

“Seaturns has been considering Mauritius for years, which has an important wave energy resource and is a country committed toward innovation. This project benefits from this strategic geographic position in Mauritius Island to support the development of the wave energy market across Southern Africa and the Indian Ocean. It also reflects Seaturns’ ambition to establish itself as the French leader in offshore wave energy, while continuing to develop its international project portfolio. Seaturns team is particularly proud to support Mauritius in its energy transition and looks forward to delivering its first commercial demonstration,” said Lawrence SIGAUD, General Manager of Seaturns in charge of Business Development.

This project will mark a key milestone for Seaturns:

• The validation of the technology in a real, grid-connected environment
• A strategic positioning in the Indian Ocean region
• The acceleration toward commercial-scale deployment

In parallel, Seaturns has started a full-scale prototype demonstration in the Atlantic Ocean in France at the end of 2025, which will continue in spring 2026 in the Nouvelle-Aquitaine region, in partnership with the Grand Port Maritime de Bordeaux.

“This project is a perfect continuation of the full-scale trials we are conducting in 2026 and 2027; it will be the ideal technical and commercial demonstration for our future farms, and it will be a way to gain comprehensive experience throughout the lifecycle of our technology” said Vincent Tournerie, Seaturns founder.

The prototype will undergo testing in real sea conditions representative of future commercial projects for a minimum period of 12 months. These trials aim to consolidate the technical and operational data required for industrial-scale deployment.

Through this project, Seaturns fully aligns with the United Nations Sustainable Development Goals and contributes to the implementation of the European strategy for the development of ocean energy, as defined in SRIA 2024 (Strategic Research and Innovation Agenda for Ocean Energy).

Seaturns is also a laureate of FRANCE 2030 program supported by Business France as part of its international development scheme. Since 2024, this support has contributed to accelerating the company’s international commercial development.
