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

A precedent-setting rate case settlement has been proposed in Pennsylvania, designed to shield residential and small business electricity customers from the soaring costs associated with the rapid expansion of data centers. The settlement, currently awaiting approval from the Pennsylvania Public Utility Commission, marks the first instance a Pennsylvania utility has agreed to such protections. The core issue stems from data centers' massive energy demands, which drive up overall electricity rates, capacity auction costs, and necessitate expensive new transmission infrastructure. Current rules often distribute these infrastructure costs across all customers. Consumer advocates, including the climate justice group POWER Interfaith and the Energy Justice Advocates, argued that residential customers should not bear the financial burden for infrastructure primarily serving large data centers. The agreement, reached between PPL Electric and over a dozen intervenors including state consumer advocates, environmental groups, and large power users like Walmart, establishes a new 'large load' customer rate class for data centers using more than 50 megawatts at peak demand (or 75 megawatts within a 10-mile radius for multiple facilities). These data centers would be required to pay for their own interconnection infrastructure costs and commit to operating for at least 10 years to prevent other customers from covering 'stranded costs' if a facility scales back or exits prematurely. Furthermore, the settlement mandates that large data centers contribute $11 million to the state's Customer Assistance Program and Low-Income Usage Reduction Program, universal service costs previously borne solely by residential customers. Public Utility Commission Vice Chair Kimberly Barrow emphasized that since data centers contribute to rising rates, they should also help compensate low-income ratepayers. While PPL Electric is preparing to more than double its system demand in 5-6 years due to data center growth, this settlement aims to manage the financial impact on existing ratepayers. The utility, based in Allentown, serves 1.5 million customers in central and eastern Pennsylvania and will also see a 4.9% rate hike for residential customers starting July 1, 2026, if the settlement is approved.
