Early last month, Greentech Media reported that NRG Energy, which owns retail electric supplier Energy Plus, would team up with Comcast in Pennsylvania to offer an electric service called Energy Rewards. Both companies are looking for new opportunities as revenue from their traditional businesses is eroding. The pilot for that partnership is now live in Duquesne Light’s service territory, which covers parts of Allegheny County around Pittsburgh and most of Beaver County, PA, serving about 580,000 people.
