AI data centers need new power. The public record shows who is asked to carry the risk before the demand is fully known. In AI Data Centers: Who Pays for New Power?, Jamie R. Collins follows six public utility proceedings across Virginia, Oregon, Ohio, Georgia, Idaho, and West Virginia. Each case reveals a different allocation device: separate customer classes, construction reimbursement, minimum billing, collateral, long service terms, exit provisions, customer-specific contracts, tracking, or regulatory oversight. Written for non-specialists, this is evidence-conscious public-infrastructure nonfiction, not a prediction of household bills or a generic AI primer. It offers a durable way to examine the next headline: identify the speaker, the document, the date, the operative obligation, and the missing result.
