"We are extremely pleasedthe Obama Administration has selected BGE for this highly competitive and coveted grant, which moves BGE's landmark Smart Grid proposal one step closer to reality. When fully implemented, BGE's Smart Grid program will be one of the most advanced in the nation and include the installation of 2 million residential and commercial smart meters.

"BGE has established itself as a leader in Smart Grid technology, having introduced an extensive pilot program in 2008 and 2009 that demonstrated customers can reduce peak electricity usage by as much as one-third andrealizesignificant savings on monthly electricity bills. The awarding of this grant by the Department of Energy is further affirmation that BGE's comprehensive Smart Grid initiative has the potential to transform the way its customers consume and conserve electricity.

"The true beneficiaries of this grant will be BGE's customers, who over the life of the project can expect to reap savings in excess of $2.6 billion, as well as improved system reliability and significant environmental benefits. We believe that our Smart Grid proposal will make a meaningful difference in the daily lives of our customers and the communities we serve.

"We now look to the Maryland Public Service Commission to complete its review and approval of our Smart Grid proposal with appropriate cost recovery, upon which the $200 million stimulus grant is contingent. It is our hope that we will receive the Commission's final approval by year's end so that we can begin providing our customers with the savings, reliability, service quality and environmental benefits as soon as possible.

"Finally, we are extremely grateful for the strong support of our Smart Grid application by Maryland's Congressional delegation, particularly Senators Barbara Mikulski and Ben Cardin and Representatives Steny Hoyer, Elijah Cummings, Dutch Ruppersberger, John Sarbanes and Frank Kratovil. They played an essential role in garnering the support necessary to ensure BGE's customers were the beneficiaries of this importantstimulus investment."
