Pennsylvania’s Power Bills Are Up 50 Percent Since 2020. The Reason Is the Data Centers.
Pennsylvania's residential electricity bills have risen significantly since 2020, with a recent report attributing the increase to the rapid expansion of data centers within the PJM Interconnection region. Lawmakers are considering three legislative changes, including requiring large-load users like data centers to supply their own dedicated generation, to mitigate these costs. The proposed changes aim to save consumers billions of dollars and address environmental concerns related to keeping older power plants online.
Residential electricity bills in Pennsylvania have surged by almost 14% in the last year and over 50% since 2020, primarily due to the proliferation of data centers across the PJM Interconnection region, according to a report by Synapse Energy Economics. State Representative Elizabeth Fiedler, Democratic chair of the House Energy Committee, highlighted the hardship this imposes on constituents forced to choose between electricity and medication.
The Synapse report, currently under review by Fiedler's committee, projects that Pennsylvania consumers could save an average of over $840 annually by 2030, totaling $2.4 billion statewide, if the legislature adopts three key changes proposed in 2024. These include mandating large-load users, such as data centers, to provide their own dedicated power generation, reducing the guaranteed return on equity for utilities for transmission and distribution, and fast-tracking clean-energy projects in PJM's interconnection queue. Patrick Cicero from the Pennsylvania Utility Law Project noted that a significant portion of utility bills covers shareholder profit rather than actual power or infrastructure.
The Data Center Coalition, represented by Dan Diorio, disputes that data centers raise energy prices, arguing that they fully cover their power consumption and that PJM's interconnection queue is the actual constraint on rates. PJM Interconnection spokesman Jeff Shields corroborated the need for faster generation development to meet the rising demand from data centers. This mismatch between rapid data center deployment and slow grid infrastructure development leads to older, more expensive coal and natural-gas plants remaining active, with costs distributed among all ratepayers, raising environmental concerns.
Pennsylvania's debate is mirrored nationally, with Virginia and other PJM states, as well as Texas, facing similar challenges. The proposed solutions in Pennsylvania, such as requiring hyperscale facilities to use dedicated, low-carbon generation, align with policies adopted in the United Kingdom and the European Union, addressing the unique and unprecedented strain placed on grids by AI-driven data center demand.
