Artificial intelligence is forcing data center operators to rethink power architecture from the utility grid to the compute rack. The challenge is no longer simply delivering more megawatts: AI is simultaneously increasing facility scale, concentrating unprecedented power density at the rack, and introducing rapid load dynamics that can propagate through upstream electrical infrastructure. This discussion examines how power strategies are evolving across the full grid-to-chip chain, from centralized UPS systems that provide facility-level resilience to in-rack battery backup and dynamic power resources positioned closer to the compute load. Key questions include:

• How is AI changing data center power architectures across locations and timescales?
• What steps are needed to manage increasingly dynamic loads?
• How can centralized and distributed power solutions work together?
• How is energy storage evolving beyond traditional backup power?
