Fujitsu Limited
Chugoku Electric Power Transmission & Distribution Co., Inc.
Fujitsu Limited (Note 1) (hereinafter “Fujitsu”) and Chugoku Electric Power Transmission & Distribution Co., Inc. (Note 2) (hereinafter “Chugoku EP T&D”) signed a license agreement on April 15, 2026, regarding intellectual property for Dynamic Rating technology (Note 3) and advanced power transmission equipment maintenance. This agreement aims to develop services that expand the adoption of renewable energy and enhance maintenance operations for power transmission facilities through the use of drones.
Under this agreement, Fujitsu will utilize Chugoku EP T&D’s intellectual property to launch the “Power Grid Advanced Operation and Maintenance Support Service” (hereinafter “the Service”) for power transmission and distribution operators. This service is designed to safely and maximally connect and utilize renewable energy within the power grid.
### [Background]
As the expansion of renewable energy progresses, power transmission and distribution operators are working to maximize the use of existing transmission facilities while maintaining the stable operation of the power system (Note 4). The capacity of transmission lines to safely carry electricity changes depending on the surrounding environment, such as temperature and wind speed. Traditionally, to protect equipment, lines have been operated based on transmission capacities calculated for “worst-case” conditions. In this context, Dynamic Rating technology—which adjusts transmission capacity based on environmental conditions—is gaining attention as a way to effectively utilize existing equipment.
Furthermore, there are concerns that maintenance tasks such as patrols and inspections of transmission facilities will face operational challenges in the future due to a shrinking labor force if traditional, manual methods are maintained. To address these issues, efforts are underway to use digital technology and drones to grasp equipment conditions efficiently and accurately.
Fujitsu has previously established a technical foundation for data management and AI analysis, as well as technology to acquire and analyze vibration data across the entire span of a transmission line using a single measuring device via optical fiber sensing technology (Note 5). To apply these technologies in a manner consistent with the actual operations of transmission and distribution operators, Fujitsu and Chugoku EP T&D have conducted repeated verifications through demonstration tests (Note 6) since September 2021, focusing on expanding renewable energy and advancing maintenance operations.
### [Service Overview]
The Service combines the intellectual property regarding Dynamic Rating and equipment operation/maintenance cultivated by Chugoku EP T&D through demonstration tests and actual operations with Fujitsu’s optical fiber sensing, data analysis, and AI technologies.
Vibration data is acquired from optical fibers installed along transmission lines. Based on environmental data such as wind conditions around the lines—obtained by converting this vibration data—the service calculates the available transmission capacity according to the real-time state of the equipment. Furthermore, by training AI models on the acquired data, it becomes possible to predict future wind conditions and transmission capacity. These sequential functions of data acquisition, conversion, and prediction are provided as the core features of the Service.
Additionally, the data obtained through these core functions can be used to support specific tasks and challenges of transmission and distribution operators. Specifically, the Service supports operational design and system construction for applying Dynamic Rating technology, which helps reduce the curtailment of renewable energy and leads to the effective use of generated power. Moreover, wind condition data around transmission lines can be used to determine drone flight feasibility and select flight routes. By understanding equipment status through vibration data, the Service also supports labor-saving and advanced maintenance operations that have traditionally relied on on-site manual labor.
Fujitsu will offer this service to transmission and distribution operators as part of the “AI Technologies and Solutions” offering under “Fujitsu Uvance” (Note 7), a business model focused on solving social issues.
**Figure: Service Overview**
### [Future Outlook]
Moving forward, Fujitsu aims to achieve advanced maintenance across the entire cycle—from inspection to repair planning—through continuous enhancement of the Service, including the use of Generative AI. This will contribute to accelerating the digitalization of power infrastructure both in Japan and overseas. Under the “Fujitsu Uvance” brand, the company will realize advanced social infrastructure through data and AI, moving toward a sustainable and resilient society.
Chugoku EP T&D will continue to advance its technology and accumulate expertise through actual operations, leading the expansion of renewable energy adoption and the advancement of equipment maintenance operations.
