July 15, 2026 Selection Results for Demonstration Projects on Watt-Bit Collaboration for FY2026

　The Ministry of Internal Affairs and Communications (MIC) hereby announces the selected demonstration projects on watt-bit collaboration, an initiative that promotes effective collaboration between electricity and telecommunications entities (watt-bit collaboration), based on the evaluation results provided by external experts.

Note: The published materials are in Japanese only.

Overview

　The growing use of AI and the increase in communications traffic are driving a rapid increase in demand for data centers and making their further development a key policy issue for Japan. Given the large amount of electricity that data centers need, their swift development requires power, telecommunications, and data center entities to work together for effective collaboration between electricity and telecommunications entities (watt-bit collaboration) in efforts to efficiently develop the electricity and telecommunications infrastructure, as stated in the GX2040 Vision – Strategy for Promoting Structural Transition based on Decarbonization: Revised Version (Cabinet Decision in February 2025) and Summary 1.0 of the Public-Private Advisory Council on Watt-Bit Collaboration (published in June 2025).

　Accordingly, MIC invited proposals for demonstration projects aimed at promoting watt-bit collaboration through the operation of distributed data centers and advanced workload shifting utilizing the All-Photonics Network (APN) and other equivalent advanced network technologies. A total of seven proposals were submitted. Based on the evaluation results provided by external experts, MIC selected all seven proposals as follows.

Call for Proposals

• Demonstration (1): Social Demonstration for Expanding Use Cases of Distributed Data Center Operation Utilizing APNs and Related Technologies
• Demonstration (2): Social Demonstration toward the Realization of Advanced Workload Shifting
