BALTIMORE, Apr 23, 2009 (BUSINESS WIRE) --Constellation Energy (NYSE:CEG) today announced that as part of the
national Take Our Daughters and Sons to Work Day(R), more than 200 children of Constellation Energy employees participated
in a day-long event, combining community service with educational activities connecting what they learn in school with their
parents' careers, including the company's core value of social responsibility.

"Through this annual event, we're providing a real-world opportunity for children of Constellation Energy employees to learn
about issues that face our community each and every day," said Mayo A. Shattuck III, chairman, president and chief executive
officer of Constellation Energy. "This innovative program is designed to provide the children an opportunity to give back in a
meaningful way, while also teaching them important lessons about the critical role corporations play in the communities they
serve. Providing such opportunities is part of our culture at Constellation Energy and is an example of what it means to put
responsible leadership to work in the community. That's a lesson we know our children will remember as they embark someday
on their own careers."

The event marks the fifth year of the Constellation Energy Kids initiative,which gives children of Constellation Energy employees
an opportunity to experience firsthand the many ways Constellation Energy and its employees give back to the community. This
year's activities focused on four issues important to the Baltimore community and to Constellation Energy -basic needs,
education, the environment and health and human services. In keeping with those themes, the children and their parents:

Prepared 700 box lunches with hoagie sandwiches and homemade cookies for distribution to Our Daily Bread, Maryland's
largest provider of meals for the poor;
Assembled 300 "baby bags" containing baby powder, wipes, ointment and other baby essentials donated by Constellation
Energy employees and targeted for delivery to area homeless shelters;
Organized and contributed to a book drive to supply children's books to local homeless shelters; and
Created an environmental art mural to commemorate their pledges to do something meaningful to help the environment.

Other events throughout the day included having the children help reduce landfill waste by taking a pledge to drink water from
reusable bottles instead of disposable plastic bottles. The kids were presented with a reusable water bottle to help them keep
their pledge. Later, the children spent the afternoon shadowing their parents at their jobs.
