Renewable Energy
Renewables
The J-POWER Group’s involvement in renewable energy spans 70 years. We are a leader in renewable energy, with one of the largest domestic market shares. We have a track record of power-related project development throughout Japan, including for large-scale hydroelectric power, geothermal power that enables stable power generation, and large wind farms.

Developments
Energy Projects
The J-POWER Group is working to expand renewable energy, and as of March 31, 2025, has increased its operating renewable energy capacity by approximately 658 MW compared with FY2017.
Over a dozen projects are underway, primarily focusing on the construction and replacement of onshore wind power in Japan. Other initiatives include offshore wind power construction, the repowering of small-scale and existing hydropower plants, and solar power development. We are pursuing further new development, targeting a 4 billion kWh increase in annual domestic power generation by FY2030 (compared with FY2022).
Offshore Wind Power Initiatives
We are actively developing offshore wind power using the knowledge gained in onshore wind power projects. In the UK, a large offshore wind farm project that we are participating in has begun commercial operation.
In Japan, we are working toward starting operation of a large offshore wind farm in Kitakyushu City, Fukuoka Prefecture.

Upcycling of Renewable Energy
J-POWER will ensure the effective use of water and wind resources by conducting a comprehensive renewal of hydroelectric power generation water turbines and generators, and rebuilding large wind turbines for wind power generation.

Global Expansion
J-POWER is also working to supply electric power from renewable energy sources in the United States, Australia and Asia.
We will contribute to the development of sustainable economies around the world through development of, and technical support consultation for, projects such as those for large-scale solar power generation, rooftop solar and pumped storage hydroelectric power generation.

Nuclear Power
Moving Forward with the Ohma Nuclear Power Plant Project, a CO2-free Energy Source
We will move forward with the Ohma Nuclear Power Plant Project as a CO2-free power source capable of stably producing large amounts of electricity, with safety as the highest priority.
The reactor core will operate solely on mixed oxide (MOX) fuel made from recycled spent fuel, and the project will help to advance the nuclear fuel cycle in Japan through spent fuel reprocessing.
