As the Sept. 28 deadline approaches for Exelon and Pepco Holdings Inc. to appeal D.C. regulators’ rejection of their merger, Mayor Muriel Bowser is saying little to indicate how she feels about a second try by the companies to close the deal.

The D.C. Public Service Commission unanimously denied Exelon's proposed $6.8 billion acquisition of Pepco Holdings Inc., sparking applause in the hearing room and sending the shares of both companies tumbling on Wall Street.

PJM generators — such as Exelon, Dynegy, NRG and PSEG — will earn $10.9 billion from this year’s capacity auction in the first test of the RTO’s new Capacity Performance requirements.

The D.C. Public Service Commission will announce its decision on Exelon’s acquisition of Pepco Holdings Inc. at its open meeting 11 a.m. Tuesday.

PJM's first capacity auction under its new no-excuses policy saw prices rise 37% to $164.77/MW-day in most of the RTO.

The NYPSC approved a temporary surcharge while a final agreement to keep the R.E. Ginna nuclear plant operating is hammered out.

A Maryland circuit court judge Wednesday declined to stay Exelon's acquisition of Pepco Holdings Inc. while it considers an appeal from the state’s Office of People’s Counsel.

Several energy companies reported their second-quarter earnings results last week.

“My guess is EPA is going to largely ignore the problem and hope that nuclear plants don’t retire,” an Exelon executive said.

PJM on Thursday delayed a vote on manual changes for the Capacity Performance plan, sidestepping a potential confrontation with anxious stakeholders.
