Offshore wind power generation is attracting attention for decarbonization.

Electric power companies and trading companies are embarking on business in Japan and overseas one after another.

The world's largest offshore wind farm was built off the North Sea in eastern England and began commercial operation on the 14th of this month.

This power plant will be able to supply electricity for approximately 800,000 ordinary households in the United Kingdom.

In addition to the German electric power company, the operating company that operates the power plant is 25% owned by Electric Power Development Co., Ltd. and 16% owned by Kansai Electric Power Co., Inc. from Japan.

Both companies aim to accumulate know-how from development to operation and maintenance methods at sea through their businesses, and utilize them when commercializing them in Japan in the future.

In Japan, the government has recruited offshore wind power generation companies in three areas, one off Chiba prefecture and one off Akita prefecture, and the business entities created by Mitsubishi Corporation and others were selected by bidding last month.

The entity plans to install 134 wind turbines in three areas, with power generation scheduled to begin in 2028 in early areas.

Offshore wind power generation is regarded as a trump card for the spread of renewable energy, as it is possible to increase the amount of power generation by increasing the scale.

However, there are still many issues to be solved, such as the amount of power generation fluctuating greatly depending on the weather and the need to strengthen the power grid that sends power to urban areas from a distance.
