Dual Fuel Generator at Macon Power Plant

MMU receives its energy across Northeast Missouri Electric Power Cooperative's transmission system at 69,000V. We have three transmission/distribution substations in which voltage is reduced to 12,470V for distribution over approximately 75 miles of primary circuitry throughout Macon.

Considerable planning, implementation, and expense has led to a very reliable and redundant electric system. In our dispatch center, staffed 24/7, system operators monitor system operating characteristics and manage our electric generation and distribution system via SCADA.

MMU's hourly system peak demand of 21 megawatts is further supported by 22 megawatts (nine (9) generators) of generation capacity. Each substation has generation capabilities for system diversity and to enhance reliability and redundancy.

In addition, MMU owns and operates the $7.6 million USD Macon Energy Center, a 10 megawatt co-gen facility located at NEMO Grain. This baseload facility operates 24/7 to provide energy to MJMEUC and steam to NEMO Grain's operation. Since its inception in May 2003, the Energy Center continues to be the most efficient gas turbine in the state and operates at an average annual capacity factor of 105 percent. In addition, it provides critical instantaneous back up power to NEMO's operation.
