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 (Case No. 1119). The commission will stream the meeting on its website and on the PSC mobile app.

FERC and state regulators in Maryland, Delaware, New Jersey and Virginia have already approved the $6.8 billion deal.

In D.C., more than half of the district’s Advisory Neighborhood Commissions and almost half of the 12 members of the city council have publicly stated their opposition to the deal. The Office of People’s Counsel and the attorney general’s office also advised against approval without significant concessions. (See Deadline Looms for Decisions in Exelon-Pepco Deal.)

Exelon says the merger would improve Pepco’s reliability. Opponents have said the deal will benefit Exelon shareholders more than ratepayers. If approved, the deal would create the Mid-Atlantic’s largest electric and gas utility.

RTO Insider will be at the PSC meeting to tell you of the decision as soon as it happens. Check our website Tuesday afternoon for full coverage.
