Duke sold the subsidiary involved, Duke Energy Retail Sales, to Houston-based Dynegy earlier this year.
While Duke asserted that all Ohio customers were treated fairly, the company agreed to pay up to $25 million to residential customers during the 2005-2008 period in question.
Duke will pay up to another $25 million to non-residential customers during that time, and $8 million will go to energy programs. Duke will also pay the plaintiffs’ legal fees and related costs.
The settlement has to be approved by a federal court in southern Ohio.
