Day-Ahead Commitment Process

​​The day-ahead commitment process (DACP) helps address reliability concerns through the advanced scheduling and commitment of resources required to meet tomorrow's expected level of demand. 


DACP for Dispatchable Generators

Dispatchable generators are required to submit their initial dispatch data between 06:00 and 10:00 EST day-ahead. The dispatch data submissions provide a declaration of the participant's capability and intent to submit dispatch data in real-time.

If their facility's real-time revenue does not cover the costs as offered for the hours included in the DACP schedule, they may receive a day-ahead production cost guarantee.


DACP for Importers

Importers that submit offers by 10:00 EST day-ahead and receive a schedule will also receive a day-ahead intertie offer guarantee to recover day-ahead as-offered costs. This is provided that their performance is consistent with their day-ahead commitment.

Importers will be subject to a day-ahead import failure charge if real-time flows are less than the megawatt quantity committed in DACP, except when conditions causing failure are outside of the importer's control.  


DACP for Dispatchable Loads

Dispatchable loads wanting to participate as dispatchable in real-time are required to submit dispatch data by 10:00 EST day-ahead.


DACP for Exporters

Exporters wanting to participate in DACP must submit their bids by 10:00 EST day-ahead. There is no financial guarantee for exports scheduled day-ahead. Exporters will be subject to a day-ahead export failure charge if real-time flows are less than the megawatt quantity committed in DACP, except when conditions causing failure are outside of the exporter's control.


Linked Wheels

Both legs of linked wheel transactions submitted in the DACP will be scheduled in equal amounts  that is the quantity that can economically navigate both interties. Day-ahead scheduled imports and exports from the same participant are considered to be implied day-ahead linked wheels for settlement purposes. Linked wheels are subject to a day-ahead linked wheel failure charge if real-time flows are less than the megawatt quantity committed in the DACP.
