ComEd Crews Mobilize to Assist in Puerto Rico Recovery

Employees to work in Puerto Rico over 60 days as part of a larger
Exelon response

CHICAGO–(BUSINESS WIRE)–As Puerto Rico continues to restore its energy system following the
devastation of Hurricane Maria, ComEd is sending crews and equipment to
assist in the restoration of power. ComEd is part of a larger response
by Exelon utilities to restore infrastructure destroyed during the
hurricane in September.

Fifty ComEd linemen, as well as support personnel, will leave for Puerto
Rico in early February. Trucks and other equipment are being sent ahead.
Crews are expected to be in Puerto Rico for an extended time working on
restoring power to residents and businesses.

ComEd’s support comes following a request by the Puerto Rico Electric
Power Authority (PREPA) asking for mainland companies to provide
assistance. The 144 employees of Exelon, the nation’s largest utility
company by customer count, will join a contingent of nearly 1,500
restoration personnel from Edison Electric Institute (EEI) member
companies. EEI immediately began coordinating with PREPA, FEMA and the
U.S. Army Corps of Engineers on the logistics of adding crews, equipment
and materials from across the country to the massive power restoration
effort that began after Puerto Rico was hit by two hurricanes in
September. Exelon utilities have been coordinating closely with EEI and
authorities to prepare for the mutual assistance effort. ComEd and its
Exelon sister utilities – BGE, Delmarva Power, Atlantic City Electric,
PECO and Pepco – are part of a contingent of more than 1,500 restoration
personnel from EEI member companies.

“This effort is very personal to many of our customers and employees who
have family and friends in Puerto Rico,” said Terence R. Donnelly, ComEd
Executive Vice-President and Chief Operating Officer. “Our teams are
eager to help and look forward to working together with other utility
workers to repair the electric infrastructure and restore power.”

Commonwealth Edison Company (ComEd) is a unit of Chicago-based Exelon
Corporation (NYSE: EXC), the nation’s leading competitive energy
provider, with approximately 10 million customers. ComEd provides
service to approximately four million customers across northern
Illinois, or 70 percent of the state’s population.
