Pepco plans to file for another rate increase this fall, parent company CEO Joseph Rigby said Tuesday, just hours before Montgomery County residents lined up to lambast the utility for its performance in restoring power after the June 29 derecho.

“We expect to file our next round of rate cases in Maryland in the fourth quarter of this year,” Rigby told shareholders in a conference call. “A fair and reasonable outcome in the next round of cases will be crucial to continue the pace of investment in Maryland.”
