Japan and Siemens Gamesa Forge Partnership to Localize Offshore Wind Supply Chains – EQ
In Short : Japan’s Ministry of Economy, Trade and Industry will sign a framework with Siemens Gamesa Renewable Energy to develop offshore wind supply chains. Siemens Gamesa will partner with TDK to produce permanent turbine magnets locally. Building on pact with GE Vernova, the deal aims to bolster Japan’s goal of deploying 45 GW of offshore wind by 2040 amid cost and auction delays.
In Detail : Japan’s Ministry of Economy, Trade and Industry is set to formalize a public–private cooperation framework with Siemens Gamesa Renewable Energy aimed at strengthening domestic offshore wind supply chains. The agreement will outline roles, investments, and technology-sharing commitments between the government and the turbine manufacturer.
Under the framework, Siemens Gamesa will work closely with Japanese partners to localize key components, streamline procurement processes, and ensure that future offshore wind projects can rely on homegrown equipment. This approach is designed to reduce costs, shorten lead times, and stimulate local industry growth.
A central element of the collaboration involves a joint venture between Siemens Gamesa and TDK to produce permanent magnets in Japan. These high-performance magnets are critical for next-generation turbine generators and help improve efficiency and reliability in harsh marine environments.
This new pact builds on a similar memorandum of understanding signed earlier this year between the ministry and GE Vernova, which focused on domestically manufacturing turbine blades and nacelle components. Together, the two agreements aim to cover the full spectrum of offshore turbine production.
Japan has set an ambitious target of installing 45 GW of offshore wind capacity by 2040, but the industry has faced cost pressures and delays in auction rounds. By localizing supply chains and fostering stronger partnerships, policymakers hope to accelerate project timelines and drive down overall capital expenditures.
Officials expect the Siemens Gamesa partnership to create thousands of skilled jobs, bolster the competitiveness of Japanese suppliers, and enhance energy security. In the longer term, the move is seen as a critical step toward meeting national decarbonization goals and establishing Japan as a leading offshore wind market.
