In 1897, Bryan’s new steam-powered generators were started for the first time. Two 60-light Wood machines provided direct current for 63 arc street lights and 20 arc lamps used for inside lighting. By 1906, the utility abandoned steam power and installed two 225-hp American diesel engines powering 150-kilowatt generators. After a series of larger diesel engine generators, Bryan installed its first combustion turbine generator in 1962. The engine of the 5,500-kilowatt General Electric combustion turbine was basically a stationary jet engine capable of burning either natural gas or diesel fuel.
Today, Bryan Municipal Utilities has almost 40 megawatts of nameplate capacity from four generators:
- Two Westinghouse gas/diesel turbines rated at 15,730 kW each
- A dual shaft GE gas/diesel turbine rated at 5,700 kW
- A 3600 horsepower, 9-cylinder, Nordberg diesel rated at 2,500 kW
In addition, our Power Plant maintains six 1,825 kW diesel generators owned by AMP-Ohio that can be drawn on during heavy load periods.
Also tied to the network is the Auglaize Hydroelectric Plant. The Auglaize plant has six generators: five Westinghouse and one General Electric.
The Power Plant provides standby generation during peak load demand, emergencies and transmission line maintenance. Power Plant personnel start and place the generators on line when required. They also work to ensure that all equipment is in generation readiness and good operating condition.
Bryan’s electric distribution circuits are monitored from the Power Plant by a computer controlled SCADA system. Any problems or irregularities are immediately brought to the operator’s attention and appropriate action is taken.
We have seven substations: one that transforms 138,000 volts to 69,000 volts and six more that distribute the power on circuits to residents, commercial customers and industries. All of the substations have direct audio communications through the fiber optic system. The system node at the utility office allows our staff to access system information through the network.
