HARRISBURG, June 5, 2026 – In response to a sharp increase in electricity prices across Pennsylvania, House Republicans have introduced legislation that would require large data centers to cover their own power generation and grid infrastructure costs. The move comes as utilities reset default supply rates on June 1, just ahead of peak summer demand.
Legislative Response to Rising Costs
The proposed Pennsylvania Electricity Ratepayer Protection Act, spearheaded by Reps. Craig Williams and Jesse Topper, aims to shift the financial burden of new data center power demand away from residential and small business customers. Williams stated that Pennsylvania families and small businesses are paying more while large data centers seek power on an already strained grid.
Utility Rate Hikes
Data from the Pennsylvania Public Utility Commission shows PECO's residential Price to Compare rose to 11.759 cents per kilowatt-hour from 11.024 cents on June 1. Other utilities, including Penelec, UGI Electric, and West Penn Power, also reported double-digit or near-double-digit percentage increases. PECO estimates the average monthly bill will increase by about $5 due to higher supply costs.
PJM Capacity Market Shock
The PJM Interconnection, which manages the grid across Pennsylvania and 12 other states plus Washington, D.C., has seen capacity prices skyrocket. According to the Institute for Energy Economics and Financial Analysis, PJM's capacity prices jumped from $28.92 per megawatt-day in 2024/2025 to $329.17 per megawatt-day for 2026/2027. Analysts attribute much of this increase to surging demand forecasts driven by data center growth, particularly for AI workloads.
Broader Market Context
However, energy analyst Paul Patterson of Glenrock Associates noted that the price surge cannot be blamed solely on data centers. Factors include capacity market rule changes, resource accreditation uncertainty, and a crowded interconnection queue. Jacques Beaudry-Losique, founder of GridSparq, emphasized that the AI build-out requires faster generation and transmission development, which the current system struggles to deliver.
Regulatory Precedents
Pennsylvania has already taken steps to address large-load demands. In April, the PUC approved a tariff framework for users exceeding 50 megawatts individually or 100 megawatts combined, placing the cost of new infrastructure on those users. PUC Chairman Steve DeFrank said regulators acted proactively to prevent the problem from overwhelming the system.
Consumer Assistance
Utilities and regulators are directing customers to bill assistance programs, including LIHEAP, PECO's Customer Assistance Program, weatherization support, hardship grants, payment plans, and budget billing. These resources have been highlighted following the June 1 rate changes.
Political Outlook
The bill now sits with the House Energy Committee. Williams and Topper acknowledged that lawmakers must decide whether to move from discussion to action before the next wave of large-load projects connects to the grid. The outcome remains uncertain as the state grapples with balancing economic growth from data centers and protecting ratepayers from rising energy costs.
