NEW YORK, Nov 1 (Reuters) - U.S. energy regulators

rejected an amended interconnection agreement for an Amazon ( AMZN ) data

center connected directly to a nuclear power plant in

Pennsylvania, a filing showed on Friday.

Members of the Federal Energy Regulatory Commision 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.
