ANECDOTE

Phoenix Demo Shows Flexible AI In Practice

  • Varun Sivaram described a Phoenix demo where AI servers reduced power by 25% during peak demand while maintaining performance.
  • The demonstration showed flexible AI can provide grid relief without compromising AI tasks.
INSIGHT

Collision Between AI Growth And Aging Grid

  • AI data centers and the aging grid are on a collision course that could stall AI growth and raise costs.
  • Without flexibility, data center demand could grow from 4% to 12% of U.S. power by 2030, straining the grid.
ADVICE

Shift AI Timing To Use Stranded Capacity

  • Make AI data centers modestly flexible in timing to consume stranded capacity and avoid peak stress.
  • Trim demand briefly (e.g., 25% for a few hours) to fit vast AI load onto existing grids.
