The campus is heated by the steam that is produced as a by-product of the production of electricity in the University's own power plant. Essentially heating the campus is "free". The plant and many of the utilidors through which the steam is distributed are old and in need of repairs that will cost close $100 million. In my 16 years on campus we had four major outages. A couple of times we got well into the evacuation process before things were repaired. Many homes use glycol in their heating systems, but it is not possible when using steam heat.
