Big Tech's AI data center plans, which are set to need an estimated 44GW of additional capacity by 2028, face a power crunch that could deflate the AI “bubble”

A lack of electricity for new data centres could deflate the AI ‘bubble’  —  Rafe Rosner-Uddin in San Francisco …

Financial Times

Context & Ripple Effects

This is the latest constraint in coverage that has moved from rising AI electricity use to a global data-center buildout already confronting capacity and return-on-investment limits. The reported 44GW requirement makes power availability, rather than announced computing plans alone, the near-term test for expansion.

The pressure is already spreading through the supply chain: AI-driven electricity demand has contributed to a gas-turbine supply crunch while Big Tech’s energy buildout has raised concerns about effects on household and small-business bills.

First-order effects

  • Power availability becomes an immediate gating factor for Big Tech’s planned AI data-center capacity, putting projects without secured electricity at risk of delay or revision.
  • The estimated additional 44GW requirement intensifies competition for grid connections and generation capacity among AI data-center developers.

Second-order effects

  • Equipment and power suppliers face stronger demand, but the existing gas-turbine supply crunch means added generation is not a frictionless workaround.
  • Cloud and AI infrastructure plans may have to prioritize locations and projects with available power, making build schedules and unit economics less predictable.

Third-order effects

  • If power constraints persist, AI infrastructure investment will be paced increasingly by utility and generation buildout rather than by chip procurement or data-center construction alone.
  • The gap between planned capacity and deliverable power could sharpen scrutiny of AI infrastructure returns, reinforcing the ROI concerns already attached to the broader buildout.

The trend: AI’s expansion is turning electricity access into a core competitive and financial constraint for data-center growth.
