Mitsubishi has confirmed that it is quitting three offshore wind projects in Japan, citing a “significantly changed” business environment for the sector, having denied reports yesterday that it had made such a decision.

Mitsubishi issued a statement today recalling that in February it had put its plans to develop three offshore wind farms under review as a result of “unexpected changes in the business environment.”

“As a result of the review, we have decided not to proceed with the development of the projects,” it said.

The domestic conglomerate dominated Japan's first state-run offshore wind auctions in 2021. There it led consortium groups that bid successfully for two projects off the coast of Akita prefecture in 2021, and also another area off the Chiba prefecture to the east of Tokyo.

Development plans for the areas, with a total projected capacity of 1.76GW, pointed to start-up dates between 2028 and 2030.

In its statement today, Mitsubishi said that since its selection as the operator of these projects, “in the wake of the pandemic and the Ukraine crisis, the business environment for offshore wind power has significantly changed worldwide due to factors such as tight supply chains, inflation, exchange rates, and rising interest rates.”

“To adapt to these unexpected changes, we have been pursuing various options including reassessment of costs, project schedule, and revenue. However, after discussions among the partners, we have determined that establishing a viable business plan is not feasible given the current conditions.”

Most of the losses have already been accounted for, it said, and additional losses are expected to be “limited.”

Mitsubishi said that it continues to recognise renewable energy, including offshore wind, is an “essential element of Japan’s energy mix” and that it remains committed to working towards a “decarbonised society.”

News that Mitsubishi had decided to quit the projects first broke yesterday in local business daily Nikkei. However Mitsubishi issued a statement later in the day denying this, saying it had yet to make its decision.

Japan’s Ministry of Economy, Trade and Industry (METI) has been trying to find a formula for rescuing the inaugural tender that Mitsubishi dominated back in 2021, but is running into opposition from some of the companies the conglomerate outbid.

Yesterday, Reuters reported that METI had proposed revising guidelines to extend the leases for the project areas by 10 years, from the current 30, to help shore up project economics.
Japan conducted a second offshore wind tender that concluded in 2023, with 1.4GW of fixed-bottom capacity projects awarded to developers including Germany's RWE, Spain's Iberdrola and UK oil major BP.

A third round saw an all-Japanese consortium made up of JERA, Green Power Investment and Tohoku Electric selected ahead of two other proposals for the 615MW Aomori project and another consortium made up of Marubeni, Kansai Electric, BP, Tokyo Gas and Marutaka see off three other proposals for the 450MW Yamagata project.
