Musk Warns of at Least 15 GW AI Power Shortfall by 2027

Speaking virtually at the G20 Innovation Ministerial in North Carolina, Elon Musk said electricity supply is becoming a binding constraint on AI infrastructure. He projected a power shortfall of at least 15 GW for AI chips by 2027, arguing that AI-chip production is expanding faster than available electricity supply.

Musk said AI-chip production has been increasing at 40–50% annually, while electricity supply outside China is growing at 10–20% a year. On that basis, he said SpaceX is building its own power plants, describing dedicated generation as the only way to secure the required capacity.

The comments point to a potential shift toward behind-the-meter generation for data-center and AI loads, rather than relying solely on conventional grid interconnection. The source also cites Amazon’s planned 7.65 GW gas-fired power plant at GW Ranch in Pecos, Texas, adjacent to a dedicated data-center campus. The project is described as planned, not built or operating.

For developers and infrastructure investors, the implication is that power procurement may increasingly determine where large AI campuses can be developed. If the projected shortage emerges, sites with assured generation, fuel supply and faster routes to grid and energy infrastructure could hold a material advantage over locations dependent on conventional connection timelines.

The source further reports that Alphabet’s Google Cloud division has agreed to pay $920 million per month for access to roughly 110,000 Nvidia GPUs through SpaceX, beginning in October 2026. The available material provides limited context on the arrangement and does not include primary documentation or comments from the parties.
