The sum of Capacity Supply Obligations (CSO) values of ISO-NE internal generators.This values is the same as Line 3a of the Morning Report.

Capacity that is anticipated to be unavailable due to cold temperatures.

The sum of capability of all generation either scheduled Out Of Service (OOS), forced OOS or reduced for the day, as known at the time of the Forecast development. Same item as item 3C on the Morning Report.

This is a manually entered value that represents the portion of a generator(s) that does not have a Capacity Supply Obligation but has elected to offer this capacity into the energy market. It shall be based on historical data.

Total Installed Capacity -PLUS- Anticipated De-List MW Offered -Minus- Other Generation Outages

The sum of Net Capacity deliveries from New York Power Pool (NYPP), New Brunswick (NB) and Hydro Quebec (HQ) in the projected peak load hour. Same as Item 3E in Morning Report.

Total Generation Available - PLUS- Imports at the Time of Peak

Peak Load Forecast for the day. Same as item 3G of the Morning Report.

In addition to the Operating Reserve Requirements, ISO will maintain a quantity of Replacement Reserves in the form of additional TMOR for the purposes of meeting the NPCC requirement to restore its Ten-Minute Reserve. The Replacement Reserve Requirement may be reduced to zero based upon ISO ability to restore Ten-Minute reserve within NPCC requirements. Same as Line 3K of the Morning Report.

The sum of capability required to cover 100% of first contingency loss within 10 minutes and 50% of the second contingency loss within 30 minutes. Same as item 3H on the Morning Report.

The sum of the Required Reserve and the Replacement Reserve.

Projected Peak Load -PLUS- Required Reserves. Same as Item 3I on Morning Report.

Total Available Generation and Imports -MINUS- Total Load plus Required Reserves. Same as Item 3L of the Morning Report.

This value represents the available relief that can be obtained from Real-time Demand Response Resources with Capacity Supply Obligations in the Forward Capacity Market. This capacity can be used when the available supply cannot meet the demand and reserve requirements. It is part of the initial OP-4 Action and is used to help maintain the ISO-NE 30 minute reserves. It can be activated in Real-time or in advance when OP-4 conditions are forecast.

This value represents the available relief that can be obtained from Real-time Emergency Generation Resources with Capacity Supply Obligations in the Forward Capacity Market. This capacity can be used only after ISO-NE has declared the OP-4 Action where a Power Watch is declared. It is used to help maintain ISO-NE 10 minute reserves, and can only be dispatched in Real-time.

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.
