The Federal Energy Regulatory Commission (FERC) rejected an effort Friday to allow an Amazon data center to tap into additional power from a nearby Pennsylvania nuclear plant. The decision could

Nuclear-power stocks fell after regulators voted against a deal between Amazon and Talen Energy. The deal would permit a Talen nuclear plant to provide an Amazon data center with extra power. Nuclear stocks have surged this year as AI data centers boost energy demand.

U.S. energy regulators rejected an amended interconnection agreement for an Amazon data center connected directly to a nuclear power plant in Pennsylvania, a filing showed on Friday. Members of the Federal Energy Regulatory Commission said the agreement to increase the capacity of the data center located on the site of Talen Energy's Susquehanna nuclear generating facility could raise power bills for the public and affect the grid's reliability.

Supporting the development of data centers — including providing the enormous amounts of electricity they require — is a matter of national security, a top federal energy regulator said.

By Laila Kearney NEW YORK (Reuters) -Costs and reliability concerns related to the burgeoning trend of building energy-intensive data centers next to U.S. power plants were the focus of a technical conference held on Friday by the Federal Energy Regulatory Commission.
