Exelon bid to buy Pepco gets boost

The District of Columbia Public Service Commission on Wednesday gave new life to Exelon Corp.'s $6.4 billion bid to merge with Pepco after flatly rejecting the deal last summer.The three-member commission voted unanimously to consider a settlement that D.C. Mayor Muriel Bowser (D) reached earlier this month with Exelon that included $78 million in benefits, including ratepayer assistance, solar-energy subsidies and job guarantees.
