Maryland Chamber of Commerce Visits Calvert Cliffs Nuclear Power Plant

Chamber expresses support for nuclear joint venture between Constellation Energy
and EDF Group and potential for a new nuclear unit at Calvert Cliffs
BALTIMORE--(Business Wire)--
The board of the Maryland Chamber of Commerce visited Constellation Energy`s
(NYSE:CEG) Calvert Cliffs Nuclear Power Plant in Lusby, Md. today. The Chamber
expressed support for a nuclear joint venture between EDF Group and
Constellation Energy and the potential for construction of a new nuclear unit at
the site. Calvert Cliffs has been identified as the possible site for a new
1,600-megawatt pressurized water reactor that would deliver enough emission-free
electricity to power 1.3 million homes.

"Calvert Cliffs has long been a driver of the Maryland economy, providing jobs
and a reliable supply of emission-free power generation in the state," said
Kathleen Snyder, president and CEO of the Maryland Chamber of Commerce. "The
addition of a third reactor at Calvert Cliffs would add thousands of new jobs in
Maryland and deliver additional baseload electricity for Maryland`s businesses."

In addition to helping Maryland meet its energy and climate change goals, the
privately funded initiative to build a new nuclear unit would be one of the
largest industrial development projects in Maryland history, resulting in 4,000
construction jobs and 400 permanent operational positions. The Nuclear Energy
Institute estimates that nuclear power plants pay 36 percent more than the
average salaries for a local area, and that the average nuclear power plant
generates $430 million in sales of goods and services in the local community and
almost $40 million in total labor income.

As part of the agreement to acquire a 49 percent interest in Constellation
Energy`s nuclear subsidiary, EDF plans to develop a new visitor and
environmental center at Calvert Cliffs to showcase sustainable energy
technologies, and move EDF`s North American headquarters to Maryland.

"Maryland`s business community knows the value of having a reliable baseload
power source in the state, and recognizes the benefits that a major new
infrastructure project and generation asset will bring to the local economy,"
said Michael J. Wallace, vice chairman and chief operating officer of
Constellation Energy. "Calvert Cliffs Nuclear Power Plant continues to be vital
to Maryland`s business community, and the potential addition of a new unit at
the site will reduce the state`s reliance on out-of-state energy suppliers and,
over time, help Maryland`s business and residential consumers better manage the
cost of electricity."

Members of the Maryland Chamber`s board visited the existing 1,735-megawatt
nuclear power plant, which first went online in 1975, and which is recognized
internationally for its high level of performance. Calvert Cliffs Unit 2 set a
world record this year for pressurized water reactors by operating non-stop for
more than 692 days, and in 2008 had a record capacity factor, a measure of
efficiency, of 101.37 percent. The site was also recognized by the Maryland
Occupational Safety and Health Administration with a Voluntary Protection
Program (VPP) Star level rating, the highest safety rating for employers in
Maryland and nationwide.
