Promoting Local Production and Consumption of Renewable Energy through Watt-bit Collaboration

Current research

The widespread adoption of generative AI is leading to a rapid increase in electricity demand for data centers (DCs). Meanwhile, the introduction of renewable energy (RE) is progressing toward achieving carbon neutrality. However, RE power generation fluctuates by region and time, so it often does not align with DCs' energy demand, making effective utilization of RE challenging. Establishing new approaches to resolve such supply-demand mismatches has become a critical challenge.

To address this challenge, the Space Environment and Energy Laboratories are working to maximize RE utilization through "Watt-bit collaboration"* via two approaches: "energy/ICT-resource integration-control technology" and "DC placement optimization technology."

Energy/ICT-resource integration-control technology aims to utilize RE effectively and optimize the energy-supply-demand balance by flexibly controlling DC processing loads (workloads: WL) and battery charging/discharging based on the RE-generation conditions. In the meantime, DC-placement optimization technology supports the selection of optimal candidate sites by evaluating factors such as RE utilization rates and costs for future development of DCs.

By establishing and implementing these two technologies, we will maximize RE utilization and contribute to achieving carbon neutrality.
