MISO emergency event levels and what they mean

Step 1: All available resources are in use, including emergency-only generation.

Step 2: MISO is energy-deficient and needs to decrease demand, like through a public appeal to curtail customers’ energy usage.

Step 3: Operating reserves are depleted, and operators should continue actions to decrease demand.

Step 4: Emergency energy needs to be purchased from other regions, if available.

Step 5: Controlled power outages should be implemented.
