RWE and Partners Secure 684 MW Japanese Offshore Wind Site

RWE Offshore Wind Japan Murakami-Tainai K.K. has been selected in a consortium together with Mitsui & Co., Ltd (Mitsui) and Osaka Gas Co., Ltd. (Osaka Gas) to deliver a 684 MW commercial-scale offshore wind project in Japan.

The Japanese Government has appointed the consortium to develop, construct, and operate a fixed-bottom offshore wind farm off the country’s west coast.

As a next step, the partners will coordinate with the Japanese Ministry of Economy, Trade and Industry (METI) and the Ministry of Land, Infrastructure, Transport and Tourism (MLIT) for the approval of the public occupancy plan. 

In addition, the partners said they will continue to engage and work together with local partners, authorities, communities, and fisheries to ensure a seamless realisation of the offshore wind farm.

“Offshore wind is increasingly gaining momentum in Japan and I am deeply honored that we together with our Japanese partners have been selected to deliver this project as a trusted partner to the Japanese Government. This marks RWE’s first success in an offshore wind tender in Japan and the wider APAC region,” said Markus Krebber, CEO of RWE AG.

Located off the coast of the cities of Murakami and Tainai, Niigata Prefecture, the offshore wind project is expected to consist of 38 wind turbines.

According to RWE, full commissioning is scheduled for June 2029.


The Japanese government aims to deploy 10 GW of offshore wind capacity by 2030 and 30-45 GW by 2040, including floating wind, as part of its target to reach net-zero emissions by 2050.

When it comes to RWE, the company currently operates 19 offshore wind farms with two projects under construction in Europe and further offshore projects under development worldwide.

The company plans to grow its global offshore wind capacity from 3.3 GW today to 10 GW in 2030, according to RWE.
