Regulators in the District of Columbia rejected the proposed merger of power companies Exelon and Pepco on Tuesday, Aug. 25, 2015 saying the deal would not benefit ratepayers. The three-member D.C. Public Service Commission voted unanimously to reject the merger. It had already been approved by the Federal Energy Regulatory Commission and by Delaware, Maryland, New Jersey and Virginia, leaving the District as the final regulatory hurdle.

Governor J.B. Pritzker is threatening to veto a clean energy compromise deal. The newly reached compromise between Senate Democrats and labor leaders is being hailed as a job-saving, planet-protecting, corruption-fighting measure. Pritzker says the current plan doesn’t go far enough in terms of ethics and transparency, must end carbon emissions by a certain date, and needs to be vetted. Tension over the issue is growing between the Pritzker administration and Senate President Don Harmon’s staff.
