Summary
This is a consortium project that has been consigned by the Ministry of the Environment
to demonstrate the largest 2 MW class tidal power generator in Japan at Naruseto off
the coast of Goto City, Nagasaki prefecture.
The consortium consists of Kyuden Mirai Energy, Nippon Steel Sumikin Engineering,
Nagasaki Marine Industry Cluster Promotion Association and Openhydro Technology Japan.
The purpose of this project is to promptly put into practical use, a tidal power
generation system which has low environmental impact and which will operate seamlessly
in Japan's particular weather and oceanic conditions.
The project period is scheduled for fiscal 2016 to 2019. The main activities in fiscal
2016 are as follows.
(2) Consultation on acquisition of license
(3) Engineering of the tidal generator system
(4) Initial procurement of components and parts of the tidal generator system
(5) Tidal flow simulation
The consortium gained the understanding and cooperation of the local stakeholders in
FY 2016, carried out the tidal flow, and soil surveys and decided on the site for turbine
system installation.
In addition, the consortium has engineered the turbine generator, begun detailed
design of the foundation structure, the installation of the subsea and land cables,
and is developing the installation method for the turbine system.
For the next fiscal year, the ClassNK’s certification, grid interconnection,
consultation on construction plan approval will be undertaken and procurement of
parts and assemblies of the turbine system will continue.
This project is a collaborative project between the Ministry of the Environment (MOE)
and the Ministry of Economy, Trade and Industry (METI). At the Development Study Meeting,
the consortium made a report on progress to and received advice from the experts, MOE
and METI on the project.
