NEW YORK, July 19 (Reuters) - Some information systems

at Exelon Corporation ( EXC ) and its local electric and natural

gas utilities were affected by the global tech outage, the U.S.

power company said on Friday.

Exelon ( EXC ), which is based in Chicago and is one of the largest

electric companies in the United States, said it was still

assessing the impact of the cyber disruption.

"As a result of a third-party worldwide technology issue, we

have implemented processes to continue to support operations,

including processing and responding to electric and natural gas

emergencies and outages safely and reliably," Exelon ( EXC ) said in a

statement. "We are continuing to assess the impact of this

third-party event and activate contingency and recovery plans."

Several U.S. power utilities, including one run by the

City of Corpus Christi, Texas, reported issues in connection

with worldwide cyber outages across numerous industries

following an update by CrowdStrike ( CRWD ) for Microsoft

Windows hosts.
