Note: Binding transmission constraints can produce instances where more than one unit is marginal in the system. Consequently, more than one fuel may be on the margin; and since each marginal unit is included in the analysis, the percentage may sum to more than 100%.

Minimum Generation ActionsSupply surplus situations during light load periods when on-line resources need to operate at Emergency Minimum levels or be decommitted as to not over burden the interconnected system.
Maximum Generation ActionsSystem-wide or transmission contingency related capacity shortages that may jeopardize the reliable operation of all or part of the MISO system.
