Minnkota, members navigate Maximum Generation Event

On Saturday, Jan. 24, Minnkota and its members navigated through an extended Maximum Generation Event declared by Midcontinent Independent System Operator (MISO).

A Maximum Generation Event is an emergency signal that electricity demand is very high and may soon exceed the amount of power available on the MISO grid, which covers 15 states in the central U.S. When this happens, utilities are asked to run every available generating resource and reduce demand wherever possible to keep the electric system stable. MISO attributed the event to below-normal temperatures, forced generation outages and higher than forecasted load.

While the conditions were serious, the event passed without any major grid reliability problems. Utilities were not required to implement rotating outages or service interruptions.

During the event, energy market prices rose to extremely high levels as MISO managed limited power supplies. Minnkota utilized a variety of strategies and all available resources to limit exposure to these high prices. All of Minnkota’s coal-based generating units were running during the event. Hydroelectric resources were also operating, providing steady output. Wind generation operated at lower levels.

In addition to generation, Minnkota fully activated its demand response program. This program allows the cooperative to temporarily reduce off-peak electrical loads across its system, lowering overall demand during critical periods.

By using every available generating resource and managing demand carefully, Minnkota successfully navigated the Maximum Generation Event while working with its members to limit risks and maintain system stability.
