Oral arguments by the owner of the Sears Tower, and QST Energyagainst Commonwealth Edison (ComEd) were heard yesterday by theIllinois Commerce Commission (ICC). Tower Leasing and QST arefighting ComEd’s refusal to allow installation of a cogenerationsystem at the tower that would save tenants an estimated $2 millionor more a year in energy costs. So far, ComEd has refused to allowQST to acquire or lease Edison’s distribution system inside theSears Tower, a prerequisite to installing the cogeneration (seeNGI May 5, 1997).
