What happened
In a CNBC interview on September 2, Berkshire Hathaway's new CEO Greg Abel said the biggest constraint on AI data centers is the power grid, not chips or capital. He noted that data centers already make up roughly 8% of Berkshire Energy's load in Iowa.
Why it matters
Abel's comments highlight that AI infrastructure growth depends on physical energy supply and site readiness. Research cited in the article shows data centers are the largest driver of U.S. electricity demand growth, but permitting and interconnection delays slow new supply.
What to watch
Abel said Berkshire Energy will serve hyperscalers only if it does not raise rates for other customers and must provide a net benefit. This could shape how utilities approach large AI deals amid political friction over data center-driven utility bills.
