Mitsubishi Corporation has announced its withdrawal from three offshore wind projects in Japan, citing significant changes in the economic environment that have impacted project viability. The decision marks a setback for Japan's offshore wind ambitions as the country struggles with slow development, high costs, and a challenging energy transition.

In a statement released on August 27, Mitsubishi pointed to "tight supply chains, inflation, exchange rates and rising interest rates" as factors that have shifted the feasibility of the projects since the consortium secured them in a 2021 government tender.

The exit comes as the global offshore wind sector faces mounting challenges, including cost overruns in Europe and regulatory headwinds in the U.S. The withdrawal is a blow to Japan's efforts to increase renewable energy generation and reduce reliance on fossil fuels.

According to Umer Sadiq, Japan analyst at BloombergNEF, this development could further jeopardize Japan's 2030 renewable energy targets. With uncertainties surrounding the restart of nuclear power plants, the country may continue to depend on liquefied natural gas (LNG) and coal, complicating both its energy security and decarbonization goals.

Mitsubishi said most of the financial losses related to the projects have already been accounted for, including a ¥52.2 billion ($352 million) charge recorded earlier this year. Consortium partner Chubu Electric Power expects an additional ¥17 billion in losses but does not anticipate revising its annual earnings forecast.
