Precedent-setting Pa. rate case to protect residential electricity customers from data center costs

A recently proposed Pennsylvania rate case settlement aims to protect residential and small business electricity customers from bearing the increasing costs associated with data center expansion. The settlement, involving PPL Electric and more than a dozen intervenors including consumer advocates and environmental groups, establishes a new rate class for large-load data centers. This marks the first time a Pennsylvania utility has agreed to shield average ratepayers from these specific data center-driven costs. According to the agreement, large-load data centers will be responsible for the infrastructure costs required for their interconnection to the grid, rather than these expenses being shared by all customers. This addresses concerns from consumer advocates, such as the Energy Justice Advocates represented by EarthJustice attorney Devin McDougall, who highlighted the "unprecedented spike in demand for electricity" from data centers driving up utility service costs. The new rate class would apply to facilities using over 50 megawatts at peak demand or multiple facilities combining for at least 75 megawatts within a 10-mile radius, requiring them to commit to 10 years of operation or face penalties. Furthermore, PPL Electric would become the first utility to require these large data centers to contribute $11 million to universal service costs, which support low-income customer assistance programs, a burden previously borne solely by residential customers. Public Utility Commission Vice Chair Kimberly Barrow emphasized that since data centers contribute to rising rates, they should help compensate low-income ratepayers. The settlement, which would also grant PPL $275 million in additional revenue and increase residential rates by 4.9% starting July 1, 2026, still requires approval from the Pennsylvania Public Utility Commission. Cleanview estimates Pennsylvania currently has 11 operating data centers with up to 95 MW capacity and 38 planned projects that could require up to 19,632 MW, highlighting the scale of the demand PPL is preparing for, which is more than double its current peak system demand.
