Pa. Public Utility Commission advances measure that aims to protect ratepayers from data center demand

The Pennsylvania Public Utility Commission (PUC) recently advanced guidance for energy companies regarding the connection of high-demand electricity users, specifically data centers. This move comes as the acceleration of artificial intelligence has significantly boosted energy demand, leading to concerns about higher electricity bills for ratepayers. PJM Interconnection, the region's electrical grid manager, has attributed increased demand and capacity costs, which led to a 10-20% rise in residential bills last year, partly to the growth of data centers. The PUC's proposed model tariff, described as recommendations rather than binding regulations, aims to facilitate quick grid connections for large energy users while shielding ratepayers from potentially higher costs. It defines large-load customers as those requiring over 50 megawatts individually or 100 megawatts in aggregate. Key recommendations include imposing fees on developers who prematurely terminate contracts, preventing ratepayers from subsidizing abandoned infrastructure, and mandating contributions from large-load customers to universal service programs. PUC Chairman Stephen DeFrank emphasized the critical juncture for the electrical grid, noting the "explosive load growth" from data centers and advanced manufacturing. During the hearing, the PUC approved two amendments introduced by DeFrank to further protect ratepayers: one permitting large-load customers to construct their own infrastructure upgrades when feasible, and another recommending electric distribution companies recover all necessary transmission and distribution costs directly from these customers, except for pre-planned upgrades. Currently, infrastructure costs are often spread across all ratepayers, contributing to increased bills. Elizabeth Marx, executive director of the Pennsylvania Utility Law Project, expressed concerns that without binding regulations, transmission and distribution system upgrade costs could still be passed on to residential and small business customers. The Data Center Coalition, an industry trade group, commended the PUC for creating a structured framework, stating it is "generally structured, transparent, and workable" and that the industry will remain engaged to ensure fair cost allocation. However, Marx underscored the need for additional legislative measures, as the model tariff is not binding, and urged electric distribution companies to follow the commission's model in their own proposed tariffs. PECO, an energy company, affirmed its commitment to protecting customers from higher costs and ensuring large-load projects do not negatively impact ratepayers.
