Data Center Knowledge reports that three U.S. utilities are making the case that large data center customers, by contributing substantial load and revenue, can help reduce per-unit electricity costs for residential ratepayers through economies of scale and infrastructure cost sharing. The argument runs counter to concerns raised in El Paso and Virginia this week, where analysts flagged data center growth as a driver of higher ratepayer bills. Regulators in multiple states are expected to scrutinize utility rate design proposals more closely as data center load growth accelerates.
