BALTIMORE, Jan. 17, 2006—Constellation Energy (NYSE: CEG) today announced that its subsidiary, Constellation NewEnergy, has been selected as the electricity supplier of choice by Connecticut Consortium Cooperative Purchasing (CCCP). The competitive agreement with CCCP is the second aggregation group in Connecticut with which Constellation NewEnergy has a relationship. An aggregator is an entity that brings a group of consumers together to form a buying group to purchase energy in bulk.

An aggregated purchasing program for school districts and municipalities, CCCP reviewed competing offers and selected Constellation NewEnergy for its proven experience, competitive pricing and flexibility. Constellation NewEnergy and CCCP partnered to bring budget certainty in an escalating market to the 64 Connecticut school districts and municipalities that have a monthly combined load of about 70 megawatts (250 million kilowatt-hours).

“We were pleased to work closely with the CCCP over several months to understand and meet the diverse energy needs of their members,” said Michael Kagan, vice president, Constellation NewEnergy. “We serve several other aggregation groups throughout New England and the electricity offerings we provide are customized to fit each aggregation's unique membership needs and requirements.”

“Having developed many other successful consortium purchasing groups for schools and municipalities in the last 15 years, CCCP's experience, coupled with Constellation NewEnergy's expertise, enables us to bring price stability to our members through 2009,” said Edward Arum of CCCP. “This is the largest group of schools and municipalities that has aggregated its electricity needs within the state at one time.”

“I was delighted to be able to assist in procuring stable and competitive energy supplies for the schools and towns of Connecticut,” said Ray Sanzone of Turris Associates, the consulting firm representing CCCP. “With Connecticut in its final move to complete electric deregulation, having seasoned suppliers such as Constellation NewEnergy serving this aggregation is very encouraging for the market.”

“As we approached this effort to assist the schools and municipalities within this consortium, we were very fortunate to have had the experience and guidance of Jennifer Jannelle of Shipman and Goodwin to bring these contract negotiations to a successful result for everyone,” said Bob Giesen of CCCP. “With the success of this effort, many school districts have inquired about forming another consortium, and we are currently looking into that for those schools and municipalities who were not in a position to join us in the first electricity agreement.”
