Pennsylvania utility regulators, specifically the Pennsylvania Public Utility Commission (PUC), have issued a warning regarding the rapid expansion of data centers within the state. According to an independent analysis, this growth could pose serious risks to the reliability of the electric grid and lead to increased costs for consumers.

The PUC's action follows growing concerns about rising electricity demand on the PJM Interconnection grid, which supplies power to Pennsylvania and a large portion of the Eastern United States. While the study does not predict a specific number of outages, it emphasizes a significant reliability risk associated with the increasing number of large-scale data center projects and the necessary transmission infrastructure.
