A tidal energy turbine has landed in the ocean. UK-based tidal energy company, Proteus Marine Renewables\u2019 (PMR) 1.1 MW tidal energy turbine<\/strong>, the AR1100, has received certification from Japan\u2019s Ministry of Economy, Trade and Industry (METI), confirming the system meets national standards for grid-connected power generation. The turbine is now operational and delivering electricity to the Japanese national grid.<\/p>\n

A 1 kW system lands in the ocean<\/p>\n

Proteus Marine Renewables has deployed the AR1100 tidal turbine in Japan, which became the country\u2019s first ever megawatt-scale grid connected tidal energy system.<\/p>\n

Installed in the Naru Strait, the turbine will generate 1.1 MW of clean energy<\/strong>, accelerating the decarbonization of the Goto Islands\u2019 electricity supply and advancing Japan\u2019s renewable energy transition.<\/p>\n

Building on the success of the AR500 pilot project in 2021, where a 500 kW device operated in the Naru Strait maintaining a 97% turbine availability, Proteus signed an equipment supply and works contract with Kyuden Mirai Energy (KME) in November 2022 to upgrade the device to 1.1 MW capacity.<\/p>\n

Leveraging its modular architecture<\/strong>, Proteus enhanced its existing turbine\u2019s performance and efficiency by integrating advanced pitch and yaw systems, along with other improvements to achieve a 1.1 MW rating.<\/p>\n

The deployment, carried out by local vessels and resources under the supervision of the Proteus Offshore Services team, was made possible through the collaboration and expertise of key partners and suppliers in Japan.<\/p>\n

Proteus was established following a 2022 management buyout of Simec Atlantis Energy\u2019s tidal energy division.<\/strong><\/p>\n

According to Philip Archer, Managing Director of Proteus Operations Japan: \u201cDeploying the AR1100 in Japan is a testament to the dedication and expertise of our team working in collaboration with local professionals. The result reinforces tidal energy\u2019s potential as a dependable renewable source<\/a> in Japan. Our next immediate focus is the commissioning of the turbine, Japan\u2019s first ever MW-scale grid connected tidal system, and the subsequent testing and accreditation phase.\u201d<\/p>\n

Drew Blaxland, CEO of Proteus added: \u201cWith operational turbines in both the United Kingdom and Japan, we are proving the scalability of tidal energy as a viable power source for coastal communities. As Japan expands its renewable energy mix<\/strong> and reduces reliance on fossil fuels, predictable sources like tidal energy will be essential in securing a stable, sustainable energy future. Proteus remains at the forefront of this transition, bringing proven solutions to new markets.\u201d<\/p>\n

A system which is designed for optimal efficiency in tidal currents<\/p>\n

The AR1100 tidal turbine features a horizontal-axis rotor with three advanced composite blades, designed for optimal efficiency in tidal currents. The blade angles are independently controlled by electromechanical pitch systems housed in the turbine hub, allowing for real-time control for maximum energy capture and to minimize hydrodynamic loads.<\/p>\n

The device incorporates a drivetrain which transmits the mechanical power extracted at the rotor through to a permanent magnet generator<\/strong>.<\/p>\n

A state of the art electrically actuated, hydraulic locking yaw mechanism is used to rotate the nacelle so that the rotor faces the oncoming tidal flow as it reverses direction four times a day.<\/p>\n

The tidal turbine is mounted on a gravity-based support structure and connected to shore via a subsea cable, transmitting power<\/strong> directly to an onshore station, where it is converted for grid distribution.<\/p>\n

Receiving approval from the Ministry of Economy, Trade and Industry (METI)<\/p>\n

According to Drew Blaxland: \u201cReceiving METI certification is a major milestone \u2013 not only for Proteus, but for tidal energy in Japan. It confirms the AR1100 series 2\u2019s compliance with Japan\u2019s rigorous safety and technical standards and demonstrates that tidal power is now a viable, scalable solution for clean electricity generation.\u201d<\/p>\n

The project was carried out in partnership with Kyuden Mirai Energy (KME), the representative firm behind the deployment. Proteus and KME are now assessing further tidal energy deployment opportunities<\/a> in Japan. Philip Archer, adds: \u201cWe\u2019ve operated in Japanese waters<\/strong> before, so we know just how demanding the conditions can be.\u201d<\/p>\n
