Development Trends of Wind Power in Japan

1. Policy-driven and Goal Upgrades

The Japanese government, through the "7th Long-term Energy Basic Plan," has clearly proposed to increase the share of renewable energy in the power structure to 40%-50% by 2040. Among them, the installed capacity of offshore wind power is planned to reach 30-45GW, and onshore wind power will develop simultaneously. In addition, to achieve the carbon neutrality goal by 2050, Japan plans to increase the total installed capacity of wind power to 15GW by 2030, with offshore wind power becoming the core growth point.

2. Accelerated Layout of Offshore Wind Power

In recent years, Japan has accelerated the bidding for offshore wind power projects. For example, the 1GW project in Aomori Prefecture and Yamagata Prefecture is jointly developed by Jera, Marubeni, and BP. They plan to cope with inflation and supply chain pressures by optimizing bidding rules and introducing a cost-sharing mechanism. However, current projects are facing cost overruns and technical challenges. For instance, the project in Chiba Prefecture, in which Mitsubishi Corporation is involved, has been delayed due to the increase in steel prices.

3. Technological Innovation and International Cooperation

• Technical Adaptability: In response to the complex terrain and frequent typhoons in Japan, anti-typhoon wind turbines (such as the 2.5MW model of Mitsubishi Heavy Industries) and floating offshore wind power technologies have been developed. Some projects are carried out in cooperation with enterprises from Denmark, China, and other countries.
• Certification and Localization: Chinese enterprises, such as Goldwind Technology, have obtained certification from the Japanese Classification Society (such as the GW109-2.5MW model), promoting the localization of technology and accumulating experience.

4. Challenges and Adjustments

• Cost and Supply Chain: The development cost of offshore wind power has increased by 40% compared to 2018, and it needs to rely on government subsidies and cost reduction through technology.
• Natural Disaster Risks: The frequent occurrence of typhoons and earthquakes requires wind turbines to have higher safety standards, increasing the complexity of design and operation and maintenance.

Application of 4G 5G Industrial Router in Wind Power

• Remote Monitoring and Data Transmission: Wind farms are usually located in remote areas or at sea. 4G/5G industrial routers can achieve real-time data transmission, monitoring the operation status of wind turbines, power generation, and fault early warning. For example, the meteorological prediction system developed in Japan needs to rely on high-speed networks to transmit data such as wind speed and temperature to optimize power generation efficiency.
• Smart Grid and Energy Storage Management: Japan plans to promote smart grids and distributed energy systems. 5G routers support low-latency communication, coordinating the dynamic balance between wind power and energy storage devices, and improving the stability of the power grid.
• Remote Equipment Maintenance: Through the 4G/5G network, the operation and maintenance team can remotely diagnose wind turbine faults and guide on-site repairs, reducing downtime. For example, in the projects of Goldwind Technology in Japan, efficient construction management has been used to shorten the construction period, and network communication technology has played a crucial role in such cooperation.
• Safety and Disaster Response: The high bandwidth and low latency characteristics of 5G can support real-time video monitoring and emergency communication, helping wind farms to deal with sudden disasters such as typhoons and earthquakes and promptly activate protection mechanisms.

Conclusion

Japan's wind power is shifting towards the offshore field through policy support, technological upgrades, and international cooperation. However, it needs to overcome challenges such as costs and natural disasters. As intelligent infrastructure, 4G/5G industrial routers are indispensable in data management, remote operation and maintenance, and power grid coordination. In the future, they may be further integrated with AI and Internet of Things technologies to promote the efficient development of wind power.
