The AI-Energy Nexus Unpacked: Expert Dialogues at SIEW Roundtable 2025
Artificial Intelligence (AI) is revolutionising industries worldwide, offering transformative solutions to address one of the most pressing challenges of our time, climate change. Large data centres house AI model training and usage, and investment in these centres has doubled globally since 2022. The intersection of AI advancement and data centre growth has sparked serious discussions regarding power availability in recent years. At the same time, by leveraging AI’s capabilities in data analysis, optimisation, and predictive modelling, industries can enhance energy efficiency, reduce carbon intensity, and drive sustainable innovation. To address this challenge, ESI@NUS recently co-hosted a roundtable titled “The AI-Energy Nexus: Transforming the Transition to Low-Carbon Power” during Singapore International Energy Week (SIEW) 2025.
Guest Lecture by Commissioner of the United States Federal Energy Regulatory Commission (FERC)
On 30 October 2025, the ESI and NUS Sustainable Futures co-hosted a guest lecture by Ms. Judy W. Chang, Commissioner of the United States Federal Energy Regulatory Commission (FERC). Commissioner Chang began her talk by introducing FERC’s key functions and identified the current challenges facing FERC: meeting load growth – particularly driven by data centers, managing higher electricity costs due to increases in the costs of new supplies and transmission, and reforming planning and interconnection processes to enable supply adequacy. She then outlined the US FERC’s approach to ensuring supply and transmission adequacy in response to these challenges and emphasized the importance of system reliability, having transparent rules, allowing for regional flexibility, and collaboration across stakeholders in the energy sector. During the subsequent Q&A session, she and participants discussed the energy efficiency in the data centers, the application of AI in power systems and grid management, and the management of uncertainty from a regulatory perspective.
