US Power Stocks Slump After Regulator Rejects Nuclear Deal.

US power stocks, including Talen Energy Corp., dropped after the Federal Energy Regulatory Commission rejected Talen's plan to supply power to an Amazon data center near its Susquehanna nuclear plant in Pennsylvania. The decision raises concerns about the impact of data centers on electricity demand and cost shifting to other consumers. The rejection is seen as a setback for the nuclear data center thesis, with companies like Constellation Energy Corp. experiencing significant stock declines despite strong financial performance. The FERC ruling followed a technical amendment request by PJM Interconnection to increase power usage at the Susquehanna plant, highlighting the challenges of co-locating data centers with existing power plants.
