Parties opposed to the Exelon-Pepco merger told the D.C. Public Service Commission that it should not reopen the record to consider the new settlement between Mayor Muriel Bowser's administration and the companies.

A newly formed advocacy group on Friday filed its intent to acquire the district assets of Pepco Holdings Inc. and transform it into a not-for-profit utility that it said will generate about $1 billion in savings over the next 20 years.

D.C. Public Power on Friday will release details of a proposed alternative to the Exelon-Pepco Holdings Inc. merger that it says would provide up to $1 billion in benefits to the district over the next 20 years.

Exelon spokesman Paul Elsberg confirmed that the concessions the company agreed to in its bid to win D.C.’s approval of its takeover of Pepco could result in changes to the deals already struck with Delaware, Maryland and New Jersey.

With the administration and public advocate on its side, Exelon's chances of closing their acquisition of Pepco appear to hinge on winning a ‘yes’ vote from PSC Chairman Betty Ann Kane or Commissioner Joanne Doddy Fort.

The settlement reached between D.C. Mayor Muriel Bowser and Exelon contains provisions designed to persuade the PSC to approve the company’s acquisition of Pepco.

Public records show that in June alone, Pepco and Exelon lobbyists communicated more than 60 times with seven D.C. councilmembers or their aides.

D.C. Mayor Muriel Bowser and Exelon CEO Chris Crane announced Tuesday that Exelon would quintuple its concessions to $78 million in a bid to win the Public Service Commission's OK for the company’s $6.8 billion acquisition of Pepco Holdings Inc.

Chicago-based Exelon would open a headquarters in the district and offer more customer credits under a tentative agreement D.C. Mayor Muriel Bowser’s office has reportedly struck to support the company’s purchase of D.C.-based Pepco Holdings Inc.

Exelon asked the D.C. Public Service Commission to reconsider its rejection of the company’s proposed $6.8 billion acquisition of Pepco Holdings Inc.
