Japan’s Ministry of Economy, Trade, and Industry (METI) has proposed a plan to boost Japan’s inter-regional power grid capacity as part of efforts to expand offshore wind power generation in line with the government goal of achieving carbon neutrality by 2050. The transmission capacity between the northernmost island of Hokkaido and the Tohoku northeastern and Kanto eastern regions, both in the Honshu main island, is currently around 900 MW.

METI said that is considered increasing capacity to 12 GW, in order to carry more electricity from Hokkaido, which has a large potential of offshore wind farms, to Tokyo and nearby areas in Kanto, where power demand is high. METI plans to lay undersea power cables in both the Pacific and the Sea of Japan to connect Hokkaido, Tohoku, and Kanto.

The plan follows the Japanese Government setting a goal of boosting Japan’s offshore wind generating capacity to up to 45 GW by 2040.
