Gas turbine inletThe power plant has seen many changes in its history—it has gone from being a coal-fired plant that supplied energy to the Kalamazoo Psychiatric Hospital in the early 1900s to being an efficient natural gas-fired plant that provides energy to all of Western Michigan University. Much of this change was due to the University's purchase of the plant in 1994, and the push from then-Vice President of Business and Finance Robert M. Beam to have a productive and environmentally friendly plant. For his efforts, the plant was named after Beam in 2007.

The Beam Power Plant is a combined cycle power plant, which means it uses both a gas turbine and a heat recovery steam generator to generate electricity. The plant has burned natural gas solely since 1999, and currently uses five boilers to generate steam and four turbines to generate electricity.

The plant is staffed by a small number of hardworking employees who work together to keep the planting running constantly.

Overview and summary


The plant's primary source of energy is 275 psig high pressure natural gas, purchased from Consumers Energy. In case of emergencies, the plant has a limited supply of oil to use on boilers 9 and 10 as a backup. The water used to create steam comes from the city of Kalamazoo.

Power plant electricity

Electricity is generated internally at 13,800 volts through two 5 megawatt gas combustion turbines and at 480 volts through one 900 kW steam turbine and one 800 kilowatt gas engine for black start and peak shaving. Electricity is distributed to campus at both 13,800 volts and 2,400 volts and to the Kalamazoo Psychiatric Hospital at 2,400 volts.

Steam generation

Steam is generated at 200 psig, 480 degrees Fahrenheit superheat through three boilers and two heat recovery steam generators and is reduced to 60 psig through a steam turbine or two reducing stations for distributions to campus and the Kalamazoo Psychiatric Hospital. Steam is further reduced to five psig for internal plant use for the deaerators, hot lime system and steam turbine feed pump as well as a separate heating line to the hospital.

Excess electricity

Western is classified as a "non utility generator" and sells back to consumers any excess electricity generated at approximately 2-3 cents per kilowatt-hour—Consumers' marginal cost of electricity production.

Water treatment

A hot lime system is utilized in conjunction with anthracite filters and zeolite softeners to achieve zero hardness makeup water to the boilers. The 800 gallons per minute capacity of the system is capable of full 100 percent makeup.

Condensate return

Approximately 85 percent of the steam sent out is returned to the plant as condensate and directed to the deaerators.
