Magallanes Renovables

What Magallanes Renovables does

Magallanes Renovables, S.L. is a Spanish privately-held renewable energy company founded in 2009 in Redondela, Galicia, that engineers, designs and manufactures floating tidal energy platforms. Its core product is the patented ATIR (Atlantic Tidal Energy Device) - a floating barge, anchored to the seabed, that suspends counter-rotating turbines approximately 15 meters underwater to extract energy from bidirectional tidal currents. The full-scale ATIR measures 42 meters in length, weighs 350 tonnes and is rated at 2 MW per platform; a next-generation ATIR 2.0 with combined 1.5 MW output (using Blades 3.0) is in development for deployment at the Morlais site in North Wales. The company leverages mature wind and naval industry engineering to minimize technology risk, with features including modular construction, a 145-tonne ballast stabilization system, and surface-accessible powertrain design intended to reduce operating costs.

The company sells electricity (in the future) to grid operators and developers under long-dated offtake arrangements - most notably a 15-year fixed-price UK Contracts for Difference (CfD) contract awarded in 2024, with commercial generation targeted by 2026. Until commercial deployment, the company is sustained almost entirely by EU and Spanish public R&D grants (BlueInvest 2020, CDTI Misiones 2022, IGAPE/GAIN 2024) and pre-commercial engineering partnerships. Customers and partners include the UK Government (via CfD), Menter Môn (Morlais infrastructure), the European Marine Energy Centre (EMEC) in Orkney, Leask Marine and academic consortia (Tecnalia, Swansea University, Technion, University of Dublin). The company operates a wholly-owned UK subsidiary, Magallanes Tidal Energy Ltd., and is led by Founder/Chairman Alejandro Marques de Magallanes and Managing Director Mario Iglesias Casals, with a 1-10 employee headcount.

Core offering

Magallanes Renovables engineers, designs, and manufactures floating tidal energy platforms (the ATIR) that harness tidal currents to generate clean electricity. The ATIR is a 350-tonne, 42-meter floating platform with submerged counter-rotating turbines producing 2 MW of power, with a next-generation ATIR 2.0 producing 1.5 MW planned for commercial deployment. Revenue is generated through the sale of electricity under long-term Contracts for Difference (CfD) and through the engineering, construction, and installation of ATIR platforms at marine energy sites.

Product overview

Magallanes Renovables offers a unified portfolio centered on its patented ATIR floating tidal energy platform. The ATIR is a floating tidal mill that extracts energy from ocean currents using counter-rotating turbines mounted on a mast beneath a symmetric floating hull. The company is currently developing ATIR 2.0, featuring double high-output rotors with 1.5 MW combined capacity, targeting commercial deployment at sites like the Morlais project in Wales and Scottish waters. The technology leverages established wind and naval industry expertise to minimize technology risk while focusing on the unique challenges of tidal energy extraction.
