Action 9 of OP-4

Action 15 of OP-4

Days when Cold Weather Conditions are forecast to exist and the 7-Day Capacity Margin Forecast indicates a capacity margin greater than or equal to 1,000 MW.

Days when Cold Weather Conditions are forecast to exist and the 7-Day Capacity Margin Forecast indicates a capacity margin less than 1,000 MW. In addition, a Cold Weather Warning will be used for all future days within the 7-Day Capacity Margin Forecast when a capacity margin of less than or equal to 0 MW exists for days not yet declared as a Cold Weather Event.

Days when Cold Weather Conditions are forecast to exist and the 7-Day Capacity Margin Forecast indicates a capacity margin less than or equal to 0 MW for an Operating Day. Cold Weather Events are declared by 11:00 a.m. two days prior to the Operating Day. A Cold Weather Warning will be used for all future days within the 7-Day Capacity Margin Forecast when a capacity margin of less than or equal to 0 MW exists, until such time that the ISO declares a Cold Weather Event.

Energy emergencies may occur as a result of sustained, wide scale shortages in fuel availability to the region's generation resources.
