co-generation

Eastern Michigan University

Eastern Michigan University flipped the switch on its new co-generation plant Friday, making the university the first in Michigan to meet close to 100% of its campus energy needs.

Cogeneration is an efficient way to use natural gas. The plant burns natural gas to spin a turbine, which creates electricity. The hot exhaust is then funneled to a generator that creates steam heat. 

John Donegan is vice president in charge of facilities. He says the plant will be able to produce 98% of the heat used on campus, and 93% of the electricity.  

"This is the most economical, most environmentally friendly way to mass produce large amounts of electricity and steam," he says.
