Montgomery County Executive Ike Leggett said he has withdrawn the county from a Maryland investigation into Pepco’s reliability problems, outraging County Council members who said the county needs to push the electric utility to get on the right track. Leggett said he would submit a county report about the county’s problems with Pepco as part of the state Public Service Commission’s investigation of the electric company’s reliability, but the county would not participate in the probe beyond that.

The report, published in February, detailed county residents’ problems with Pepco’s service, especially after several major storms knocked out residents’ power for days. According to the report, power outages cost Montgomery residents between $22.9 million and $114.6 million and businesses between $21.1 million and $211 million.
