A federal judge has signed off on a more than $16.05 million class action settlement involving claims that Connecticut-based North American Power & Gas LLC overcharged customers.

The settlement signed off on Friday by U.S. District Judge Victor Bolden comes five weeks after another judge signed off on an $18.5 million class action settlement involving Viridian Energy. The plaintiffs in both class actions were represented by attorneys from West Hartford-based Izard Kindall & Raabe.
