Proteus Marine Renewables, a leader in ocean energy technology , has successfully completed the installation of its AR1100 tidal turbine in the Naru Strait, Japan. Generating 1.1 MW of power, the device marks a significant milestone in Japan’s clean energy transition.
The system installed in the strait between the Goto Islands will contribute to the decarbonisation of the region’s electricity grid and also reinforces Proteus’ commitment to renewable energy generation. The AR1100 turbine , which has already proven its reliability in previous projects, such as the AR500 in 2021, continues to advance with technological improvements that optimise its efficiency and performance.
AR1100 tidal turbine technology
The tidal turbine technology used in the AR1100 stands out for its ability to adapt to tidal currents, allowing it to generate energy efficiently. This ocean energy generator is equipped with an advanced pitch and yaw system, optimizing energy capture.
With a modular structure and a design that facilitates operation and maintenance, the AR1100 is positioned as one of the most promising solutions for coastal communities looking for sustainable energy sources .

A future with tidal energy
The installation of this turbine represents a crucial step in advancing tidal energy in Japan. In collaboration with Kyuden Mirai Energy, one of the leading energy companies in Japan, Proteus continues to demonstrate that tidal energy is a viable and reliable source of renewable energy.
The partnership with Kyuden Mirai, supported by Japan’s Ministry of the Environment, will be key to the expansion of this technology in the region , as Japan moves away from fossil fuels and increases its focus on more sustainable energy sources.
Decarbonisation and sustainability in the Japanese market
Japan’s energy future is increasingly geared towards predictable renewable energy sources, such as tidal power. In this context, the 1.1 MW power generated by the AR1100 in the Japanese market will contribute to reducing emissions and diversifying clean generation in the country.
With over 20 GWh of energy generated to date , Proteus continues to innovate and bring its technology to new markets, including France and the US, as it works to meet global decarbonisation goals.
