Promote Sustainability Through Sports in Illinois
As the preferred energy choice of the Chicago Blackhawks and Chicago Bulls, Constellation has been the official energy provider of the Chicago United Center since 2011. It’s why we believe in helping home-team fans save energy each season by hosting the Go Green Games, and support Illinois energy users by donating Green-e Energy Certified Renewable Energy Certificates (RECs) each and every game day.
Constellation is proud to power the United Center and the Chicago Bulls and Chicago Blackhawks practice facilities.
