Constellation Energy Releases Statement Regarding Maryland Public Service Commission`s Decision to Delay Review of the Company`s Proposed Nuclear Joint Venture with EDF Group

BALTIMORE--(Business Wire)--
Constellation Energy (NYSE:CEG) released the following statement regarding
today`s decision by the Maryland Public Service Commission (PSC) to delay its
review of the proposed nuclear joint venture between Constellation Energy and
EDF Group.

"We are disappointed that the PSC has granted the state of Maryland`s request to
delay its review of EDF`s $4.5 billion investment in Constellation Energy`s
nuclear assets. We have been working diligently to stay on the schedule set by
the PSC and had hoped that the state of Maryland would do the same given the
value of this investment to the state.

"The PSC`s review of the EDF transaction has been ongoing since February 2009.
During this time, Constellation Energy, BGE and EDF have produced in excess of
15,000 pages of documents, provided unprecedented access to senior corporate
officers for hours of depositions and testimony, and submitted numerous briefs
and expert testimony. During this entire process, neither Constellation Energy,
BGE nor EDF has asked for an extension of time to answer questions or provide
information requested by any party to this review - we have met every deadline
set for us by the PSC and the other parties to this proceeding.

"We believe that the parties have all of the information reasonably necessary to
review the EDF transaction. Any delay in a transaction of this magnitude adds to
the risk of it not closing, which would be a real loss for Maryland."
