Pennsylvania PUC to address data center impacts on electric grid, consumer costs
The Pennsylvania Public Utility Commission (PUC) is taking steps to address the impact of rapid data center development on the state's electric reliability and consumer costs. The commission approved a motion to update emergency load control procedures and examine how costs from large computational loads are allocated. These actions follow an executive order from Governor Josh Shapiro.
The Pennsylvania Public Utility Commission (PUC) has initiated steps to examine and address the growing impact of rapid data center development on the regional electric grid and associated consumer costs. In a unanimous 5-0 vote, the commission approved a motion by Vice Chair Kimberly Barrow to direct staff to develop proposed updates to the state's emergency electric load control regulations. These updates aim to clarify procedures for curtailing electricity to customers during pre-emergency and emergency conditions, ensuring clearer guidelines for managing increased load.
Vice Chair Barrow emphasized the need for a careful examination of the existing regulatory framework due to the combination of rapid load growth and tightening resource adequacy across the PJM Interconnection. The motion also includes plans for a technical conference this fall, which will focus on the allocation of costs related to large computational loads, including data centers, and their potential impact on customers not contributing to this new demand.
These actions by the PUC follow an executive order issued by Governor Josh Shapiro on August 18, which encouraged the commission to investigate data center curtailment procedures and cost allocation measures. The PUC's Law Bureau and Bureau of Technical Utility Services are tasked with preparing a Tentative Order for consideration at a public meeting on October 1, 2026. If approved, the proposal will be open for public comment, with a final order targeted for January 28, 2027.
