WEC Energy Group will sell its subsidiary Trillium CNG, a provider of compressed natural gas fueling services as well as a fueling station design, construction, operation and maintenance, said a Trillium spokeswoman representing both companies.

Trillium’s Lisa Prunty said WEC, which is based in Milwaukee, doesn't feel that Chicago-based Trillium is the “ideal company” to continue to own and that Trillium “will require additional investment for it to flourish and to develop.”

Trillium became part of WEC Energy Group on June 29, Prunty said.
