America's Electricity Grids: At a Crossroads

“Allowing or even encouraging data centers and other large loads to develop their own private grids could help address several pressing problems. First, it could insulate other customers from potential rate increases associated with utilities building infrastructure to serve data-center loads. In a fully private grid that remains physically and electrically separate from the broader system, none of the direct costs of generation or its related infrastructure could be allocated to the broader public grid and its customers.

…Second, establishing a private grid could enable large loads to avoid or streamline many of the regulatory requirements that apply to traditional electric utilities, which often slow infrastructure development.”
