Design certificate for Proteus AR1100 in Japan complete

October 21, 2024

Building on the success of our AR500 tidal project in Japan, we’re excited to share that Proteus has hit another important Phase 2 milestone on route to the installation of the AR1100 turbine in early 2025.

ClassNK, who are a certification bureau in Japan, have issued a Design Evaluation Conformity Certificate for our AR1100 system. This is an essential step in the upgrade from the AR500 to the AR1100, which features our latest pitch and yaw systems and is uprated to 1.1MW in order to dramatically boost yield.

This brings us one step closer to making tidal power a reality in Japan, with turbine assembly nearing completion soon to allow installation and commissioning in early 2025.

Once complete, this project will provide clean energy to the local Goto Islands, supporting Japan’s commitment to renewable energy. We’re proud to be working alongside our key partners—Kyuden Mirai Energy, the Ministry of Environment, Toyo Construction, Goto Transportation, and Shibuya Diving—who share our drive to bring sustainable energy to the region.

"Whilst the Design Evaluation Conformity Certificate is just a piece of paper, it attests to the immense drive, determination and talent of the team in completing the AR1100 design and the huge effort required by ClassNK in reviewing the encyclopedic documentation. Most importantly, it allows for the submission of the construction permit that is required to break ground and start the expansion works on the existing onshore powerhouse. These works will be completed by the end of 2024 and shall be followed by the installation of the AR1100 turbine. It's a significant step toward establishing tidal power as an emerging renewable energy resource in Japan. The Proteus team is very excited by what the future holds", says Philip Archer, Head of Product Applications.
