Can America's power supply keep up with AI chip demand?
Core argument: Analysts project Nvidia will sell about 6m Blackwell and 5.5m GB chips between February 2024 and February 2026, and if half land in America and run at capacity they would add 25 gigawatts of power demand.
Analysts predict that between February 2024 and February 2026 Nvidia will have sold some 6m Blackwells and 5.5m GBS. Assume that half of these end up in America, in line with its home market’s historical revenue share. If installed and operated at capacity, those chips would raise American power demand by 25 gigawatts. That is almost twice as much as all of America’s utility-scale producers added in 2022 and not far off the 27GW they managed in 2023. And that is not counting next-generation Rubin chips Nvidia plans to launch next year, or AI racks sold by rivals such as AMD, not to mention other power sinks such as electric cars. Between 2022, when ChatGPT ignited the AI boom, and the 12 months to June this year, the combined capital spending of America’s 50 biggest listed electricity providers rose by 30%, to $188bn—a compound annual increase of 7%, adjusting for inflation. According to S&P Global, a data provider, they are planning to add new plants with a collective capacity of 123GW, on top of the 565GW currently in operation. Bernstein estimates a potential power shortfall in America of 17GW by 2030 if the chips get more energy efficient, and 62GW if they don’t. Morgan Stanley puts the gap at 45GW by 2028.
